net: fix netpoll crash with bnxt

Rob run into crashes when using XDP on bnxt. Upon investigation
it turns out that during driver reconfig irq core produces
a warning message when IRQs are requested. This triggers netpoll,
which in turn accesses uninitialized driver state. Same crash can
also be triggered on this platform by changing the number of rings.

Looks like we have two missing pieces here, netif_napi_add() has
to make sure we start out with netpoll blocked. The driver also
has to be more careful about when napi gets enabled.

Tested XDP and channel count changes, the warning message no longer
causes a crash. Not sure if the memory barriers added in patch 1
are necessary, but it seems we should have them.

Netpoll can try to poll napi as soon as napi_enable() is called.
It crashes trying to access a doorbell which is still NULL:

napi_disable() makes sure to set the NAPI_STATE_NPSVC bit to prevent
netpoll from accessing rings before init is complete. However, the
same is not done for fresh napi instances in netif_napi_add(),
even though we expect NAPI instances to be added as disabled.

This causes crashes during driver reconfiguration (enabling XDP,
changing the channel count) - if there is any printk() after
netif_napi_add() but before napi_enable().

To ensure memory ordering is correct we need to use RCU accessors.

Set the skb's network_header before it is passed to the underlying

This patch fixes the following issue:

When we use this driver with AF_PACKET sockets, there would be error
messages of:
   protocol 0805 is buggy, dev (Ethernet interface name)
printed in the system "dmesg" log.

This is because skbs passed down to the Ethernet device for transmission
don't have their network_header properly set, and the dev_queue_xmit_nit
function in net/core/dev.c complains about this.

Reason of setting the network_header to this place (at the end of the
Ethernet header, and at the beginning of the Ethernet payload):

Because when this driver receives an skb from the Ethernet device, the
network_header is also set at this place.

Since commit 9c66d156 ("taprio: Add support for hardware

to the hardware:

In software mode, the gate masks are specified in terms of traffic
classes, so if say "sched-entry S 03 20000", it means that the traffic
classes 0 and 1 are open for 20us; when taprio is offloaded to
hardware, the gate masks are specified in terms of hardware queues.

The idea here is to fix hardware offloading, so schedules in hardware
and software mode have the same behavior. What's needed to do is to
map traffic classes to queues when applying the offload to the driver.

The recent changes to support user-defined RSS map assume that RX
rings are always reserved and the default RSS map is set after the
RX rings are successfully reserved.  If the firmware spec is older
than 1.6.1, no ring reservations are required and the default RSS
map is not setup at all.  In another scenario where the fw Resource
Manager is older, RX rings are not reserved and we also end up with
no valid RSS map.

Fix both issues in bnxt_need_reserve_rings().  In both scenarios
described above, we don't need to reserve RX rings so we need to
call this new function bnxt_check_rss_map_no_rmgr() to setup the
default RSS map when needed.

Without valid RSS map, the NIC won't receive packets properly.

There are no VF rings available during probe when the device is configured
using the Minimal-Static reservation strategy. In this case, the RSS
indirection table can only be initialized later, during bnxt_open_nic().
However, this was not happening because the rings will already have been
reserved via bnxt_init_dflt_ring_mode(), causing bnxt_need_reserve_rings()
to return false in bnxt_reserve_rings() and bypass the RSS table init.

Solve this by pushing the call to bnxt_set_dflt_rss_indir_tbl() into
__bnxt_reserve_rings(), which is common to both paths and is called
whenever ring configuration is changed. After doing this, the RSS table
init that must be called from bnxt_init_one() happens implicitly via
bnxt_set_default_rings(), necessitating doing the allocation earlier in
order to avoid a null pointer dereference.

The fix is to clear the BNXT_STATE_IN_FW_RESET flag and then cancel
the delayed workqueue in bnxt_remove_one().  bnxt_queue_fw_reset_work()
also needs to check that this flag is set before scheduling.  This

In preparation for removing myself from the PHYLIB entry, add the UniMAC
MDIO controller files (DT binding, driver and platform_data header) to
the GENET entry. The UniMAC MDIO controller is essential to the GENET
operation, therefore it makes sense to group them together.

When the DT binding was added in aab5127d ("Documentation: add
Device tree bindings for Broadcom GENET"), the file was not explicitly
listed under the GENET MAINTAINERS section, do that now.

When the binding was added with 967dd82f ("net: dsa: b53: Add
support for Broadcom RoboSwitch"), it was not explicitly added to the
B53 MAINTAINERS file section, add it now.
