slave_dev->name is only populated at this stage if it was specified
through a label in the device tree. However that is not mandatory.
When it isn't, the error message looks like this:

[    5.037057] fsl_enetc 0000:00:00.2 eth2: error -19 setting up slave PHY for eth%d
[    5.044672] fsl_enetc 0000:00:00.2 eth2: error -19 setting up slave PHY for eth%d
[    5.052275] fsl_enetc 0000:00:00.2 eth2: error -19 setting up slave PHY for eth%d
[    5.059877] fsl_enetc 0000:00:00.2 eth2: error -19 setting up slave PHY for eth%d

which is especially confusing since the error gets printed on behalf of
the DSA master (fsl_enetc in this case).

Printing an error message that contains a valid reference to the DSA
port's name is difficult at this point in the initialization stage, so
at least we should print some info that is more reliable, even if less
user-friendly. That may be the driver name and the hardware port index.

After this change, the error is printed as:

This patch is born out of an investigation into which IEEE statistics
correspond to which struct rtnl_link_stats64 members. Turns out that
there seems to be reasonable consensus on the matter, among many drivers.
To save others the time (and it took more time than I'm comfortable
admitting) I'm adding comments referring to IEEE attributes to
struct rtnl_link_stats64.

Up until now we had two forms of documentation for stats - in
Documentation/ABI/testing/sysfs-class-net-statistics and the comments
on struct rtnl_link_stats64 itself. While the former is very cautious
in defining the expected behavior, the latter feel quite dated and
may not be easy to understand for modern day driver author
(e.g. rx_over_errors). At the same time modern systems are far more
complex and once obvious definitions lost their clarity. For example
- does rx_packet count at the MAC layer (aFramesReceivedOK)?
packets processed correctly by hardware? received by the driver?
or maybe received by the stack?

I tried to clarify the expectations, further clarifications from
others are very welcome.

The part hardest to untangle is rx_over_errors vs rx_fifo_errors
vs rx_missed_errors. After much deliberation I concluded that for
modern HW only two of the counters will make sense. The distinction
between internal FIFO overflow and packets dropped due to back-pressure
from the host is likely too implementation (driver and device) specific
to expose in the standard stats.

Now - which two of those counters we select to use is anyone's pick:

sysfs documentation suggests rx_over_errors counts packets which
did not fit into buffers due to MTU being too small, which I reused.
There don't seem to be many modern drivers using it (well, CAN drivers
seem to love this statistic).

Of the remaining two I picked rx_missed_errors to report device drops.
bnxt reports it and it's folded into "drop"s in procfs (while
rx_fifo_errors is an error, and modern devices usually receive the frame
OK, they just can't admit it into the pipeline).

Of the drivers I looked at only AMD Lance-like and NS8390-like use all
three of these counters. rx_missed_errors counts missed frames,
rx_over_errors counts overflow events, and rx_fifo_errors counts frames
which were truncated because they didn't fit into buffers. This suggests
that rx_fifo_errors may be the correct stat for truncated packets, but
I'd think a FIFO stat counting truncated packets would be very confusing
to a modern reader.

v2:
 - add driver developer notes about ethtool stat count and reset
 - replace Ethernet with IEEE 802.3 to better indicate source of attrs
 - mention byte counters don't count FCS
 - clarify RX counter is from device to host
 - drop "sightly" from sysfs paragraph
 - add examples of ethtool stats
 - s/incoming/received/ s/incoming/transmitted/

sfc: ethtool for EF100 and related improvements

This series adds the ethtool support to the EF100 driver that was held
 back from the original submission as the lack of phy_ops caused issues.
Patch #2, removing the phy_op indirection, deals with this.  There are a
 lot of checkpatch warnings / xmastree violations but they're all in
 pure code movement so I've left the code as it is.
While patch #1 is technically a fix and possibly could go to 'net', I've
 put it in this series since it only becomes triggerable with the added
 'ethtool --reset' support.

Originally there were several implementations of PHY operations for the

Thus, there is no need to indirect through function pointers in
 efx->phy_op; we can simply call the efx_mcdi_phy_* functions directly.

This also hooks up these functions for EF100, which was previously using

net: bridge: mcast: initial IGMPv3/MLDv2 support (part 1)

This patch-set implements the control plane for initial IGMPv3/MLDv2
support which takes care of include/exclude sets and state transitions
based on the different report types.
Patch 01 arranges the structure better by moving the frequently used
fields together, patch 02 factors out the port group deletion code which is
used in a few places. Patches 03 and 04 add support for source lists and
group modes per port group which are dumped. Patch 05 adds support for
group-and-source specific queries required for IGMPv3/MLDv2. Then patch 06
adds support for group and group-and-source query retransmissions via a new
rexmit timer. Patches 07 and 08 make use of the already present mdb fill
functions when sending notifications so we can have the full mdb entries'
state filled in (with sources, mode etc). Patch 09 takes care of port group
expiration, it switches the group mode to include and deletes it if there
are no sources with active timers. Patches 10-13 are the core changes which
add support for IGMPv3/MLDv2 reports and handle the source list set
operations as per RFCs 3376 and 3810, all IGMPv3/MLDv2 report types with
their transitions should be supported after these patches. I've used RFCs
3376, 3810 and FRR as a reference implementation. The source lists are
capped at 32 entries, we can remove that limitation at a later point which
would require a better data structure to hold them. IGMPv3 processing is
hidden behind the bridge's multicast_igmp_version option which must be set
to 3 in order to enable it. MLDv2 processing is hidden behind the bridge's
multicast_mld_version which must be set to 2 in order to enable it.
Patch 14 improves other querier processing a bit (more about this below).
And finally patch 15 transforms the src gc so it can be used with all mcast
objects since now we have multiple timers that can be running and we
need to make sure they have all finished before freeing the objects.
This is part 1, it only adds control plane support and doesn't change
the fast path. A following patch-set will take care of that.

Here're the sets that will come next (in order):
 - Fast path patch-set which adds support for (S, G) mdb entries needed
   for IGMPv3/MLDv2 forwarding, entry add source (kernel, user-space etc)
   needed for IGMPv3/MLDv2 entry management, entry block mode needed for
   IGMPv3/MLDv2 exclude mode. This set will also add iproute2 support for
   manipulating and showing all the new state.
 - Selftests patches which will verify all state transitions and forwarding
 - Explicit host tracking patch-set, needed for proper fast leave and
   with it fast leave will be enabled for IGMPv3/MLDv2

Not implemented yet:
 - Host IGMPv3/MLDv2 filter support (currently we handle only join/leave
   as before)
 - Proper other querier source timer and value updates
 - IGMPv3/v2 MLDv2/v1 compat (I have a few rough patches for this one)

v4: move old patch 05 to 02 (group del patch), before src lists
    patch 02: set pg's fast leave flag when deleting due to fast leave
    patch 03: now can use the new port del function
              add igmpv2/mldv1 bool which are set when the entry is
              added in those modes (later will be passed as update_timer)
    patch 10: rename update_timer to igmpv2_mldv1 and use the passed
              value from br_multicast_add_group's callers
v3: add IPv6/MLDv2 support, most patches are changed
v2:
 patches 03-04: make src lists RCU friendly so they can be traversed
                when dumping, reduce limit to a more conservative 32
                src group entries for a start
 patches 11-13: remove helper and directly do bitops

                group timers have finished before freeing the port

Since each entry type has timers that can be running simultaneously we need
to make sure that entries are not freed before their timers have finished.
In order to do that generalize the src gc work to mcast gc work and use a

types and limits them only when multicast_igmp_version == 3 or
multicast_mld_version == 2 respectively. Now that IGMPv3/MLDv2 handling
functions will be managing timers we need to delay their activation, thus
a new argument is added which controls if the timer should be updated.
We also disable host IGMPv3/MLDv2 handling as it's not yet implemented and
could cause inconsistent group state, the host can only join a group as
EXCLUDE {} or leave it.

The wrappers in include/linux/pci-dma-compat.h should go away.

The patch has been generated with the coccinelle script below and has been
hand modified to replace GFP_ with a correct flag.
It has been compile tested.

When memory is allocated in 'vnic_dev_classifier()', 'vnic_dev_fw_info()',
'vnic_dev_notify_set()' and 'vnic_dev_stats_dump()' (vnic_dev.c) GFP_ATOMIC
must be used because its callers take a spinlock before calling these
functions.

When memory is allocated in '__enic_set_rsskey()' and 'enic_set_rsscpu()'
GFP_ATOMIC must be used because they can be called with a spinlock.
The call chain is:
  enic_reset                         <-- takes 'enic->enic_api_lock'
    --> enic_set_rss_nic_cfg
      --> enic_set_rsskey
        --> __enic_set_rsskey        <-- uses dma_alloc_coherent
      --> enic_set_rsscpu            <-- uses dma_alloc_coherent

When memory is allocated in 'vnic_dev_init_prov2()' GFP_ATOMIC must be used
because a spinlock is hidden in the ENIC_DEVCMD_PROXY_BY_INDEX macro, when
this function is called in 'enic_set_port_profile()'.

When memory is allocated in 'vnic_dev_alloc_desc_ring()' GFP_KERNEL can be
used because it is only called from 5 functions ('vnic_dev_init_devcmd2()',
'vnic_cq_alloc()', 'vnic_rq_alloc()', 'vnic_wq_alloc()' and
'enic_wq_devcmd2_alloc()'.

  'vnic_dev_init_devcmd2()': already uses GFP_KERNEL and no lock is taken
     in the between.
  'enic_wq_devcmd2_alloc()': is called from ' vnic_dev_init_devcmd2()'
     which already uses GFP_KERNEL and no lock is taken in the between.
  'vnic_cq_alloc()', 'vnic_rq_alloc()', 'vnic_wq_alloc()': are called
     from 'enic_alloc_vnic_resources()'
'enic_alloc_vnic_resources()' has only 2 call chains:

  1) enic_probe
      --> enic_dev_init
        --> enic_alloc_vnic_resources
'enic_probe()' is a probe function and no lock is taken in the between

  2) enic_set_ringparam
      --> enic_alloc_vnic_resources
'enic_set_ringparam()' is a .set_ringparam function (see struct
ethtool_ops). It seems to only take a mutex and no spinlock.

So all paths are safe to use GFP_KERNEL.

It's nice if the phy is online before we register the netdev
so try to do that first.

Stop trying to do "second tried" to register the phy, it
works perfectly fine the first time.

Stop remvoving the phy in uninit. Remove it when the
driver is remove():d, symmetric to where it is added, in
probe().

This implements the missing MTU setting for the RTL8366RB
switch.

Apart from supporting jumboframes, this rids us of annoying
boot messages like this:
realtek-smi switch: nonfatal error -95 setting MTU on port 0
