      qed: implement devlink info request · 53916a67
      由 Igor Russkikh 提交于 
      Here we return existing fw & mfw versions, we also fetch device's
serial number:

~$ sudo ~/iproute2/devlink/devlink  dev info
pci/0000:01:00.1:
  driver qed
  board.serial_number REE1915E44552
  versions:
      running:
        fw.app 8.42.2.0
      stored:
        fw.mgmt 8.52.10.0

MFW and FW are different firmwares on device.
Management is a firmware responsible for link configuration and
various control plane features. Its permanent and resides in NVM.

Running FW (or fastpath FW) is an embedded microprogram implementing
all the packet processing, offloads, etc. This FW is being loaded
on each start by the driver from FW binary blob.

The base device specific structure (qed_dev_info) was not directly
available to the base driver before. Thus, here we create and store
a private copy of this structure in qed_dev root object to
access the data.

      qed/qede: make devlink survive recovery · 755f982b
      由 Igor Russkikh 提交于 
      Devlink instance lifecycle was linked to qed_dev object,
that caused devlink to be recreated on each recovery.

Changing it by making higher level driver (qede) responsible for its
life. This way devlink now survives recoveries.

qede now stores devlink structure pointer as a part of its device
object, devlink private data contains a linkage structure,
qed_devlink.

      chelsio: switch from 'pci_' to 'dma_' API · 9ab90179
      由 Christophe JAILLET 提交于 
      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 'free_rx_resources()' and
'alloc_tx_resources()' (sge.c) GFP_KERNEL can be used because it is
already used in these functions.

Moreover, they can only be called from a .ndo_open	function. So it is
guarded by the 'rtnl_lock()', which is a mutex.

While at it, a pr_err message in 'init_one()' has been updated accordingly
(s/consistent/coherent).

      mlxsw: spectrum_ethtool: Remove internal speeds from PTYS register · 5bf01b57
      由 Danielle Ratson 提交于 
      The PTYS register is used to report and configure the port type and
speed. Currently, internal bits in the register are used the same way
other bits are used.

Using the internal bits can cause bad parameter firmware errors. For
example, trying to write to internal bit 25 returns:

EMAD reg access failed (tid=53e2bffa00004310,reg_id=5004(ptys),type=write,status=7(bad parameter))

Remove the internal bits from the PTYS register, so that it is no longer
possible to pass them to firmware.

      由 Ido Schimmel 提交于 
      On the Spectrum-{2,3} ASICs the minimum burst size of the packet trap
policers needs to be 40% of the configured rate. Otherwise, intermittent
drops are observed even when the incoming packet rate is slightly lower
than the configured policer rate.

Adjust the burst size of the registered packet trap policers so that
they do not violate above mentioned limitation.

      net: atheros: switch from 'pci_' to 'dma_' API · 85eb5bc3
      由 Christophe JAILLET 提交于 
      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 'atl1e_setup_ring_resources()' (atl1e_main.c),
'atl1_setup_ring_resources()' (atl1.c) and 'atl2_setup_ring_resources()'
(atl2.c) GFP_KERNEL can be used because it can be called from a .ndo_open.

'atl1_setup_ring_resources()' (atl1.c) can also be called from a
'.set_ringparam' (see struct ethtool_ops) where sleep is also allowed.

Both cases are protected by 'rtnl_lock()' which is a mutex. So these
function can sleep.

      ipvlan: advertise link netns via netlink · 0bad834c
      由 Taehee Yoo 提交于 
      Assign rtnl_link_ops->get_link_net() callback so that IFLA_LINK_NETNSID is
added to rtnetlink messages.

Test commands:
    ip netns add nst
    ip link add dummy0 type dummy
    ip link add ipvlan0 link dummy0 type ipvlan
    ip link set ipvlan0 netns nst
    ip netns exec nst ip link show ipvlan0

Result:
    ---Before---
    6: ipvlan0@if5: <BROADCAST,MULTICAST> ...
        link/ether 82:3a:78:ab:60:50 brd ff:ff:ff:ff:ff:ff

    ---After---
    12: ipvlan0@if11: <BROADCAST,MULTICAST> ...
        link/ether 42:b1:ad:57:4e:27 brd ff:ff:ff:ff:ff:ff link-netnsid 0
