However Artur Skawina <art.08.09@gmail.com> has shown that it can happen in reverse order as well.

Roel Kluin reported a bug in two error paths where skbs were wrongly
being freed using kfree(). He provided a fix where it was replaced to
kfree_skb(), as it should be.
However, in i2400mu_rx(), the error path was missing returning an
indication of the failure. Changed to reset rx_skb to NULL and return
it to the caller, i2400mu_rxd(). It will be treated as a transient
error and just ignore the packet.
Depending on the buffering conditions inside the device, the data
packet might be dropped or the device will signal the host again for
data-ready-to-read and the host will retry.

Contrary to what the docs say, the 'extended interrupt cause' bit in
the interrupt cause register (bit 1) appears to not be maskable on at
least some of the mv643xx_eth platforms, making writing zeroes to the
interrupt mask register but not the extended interrupt mask register
insufficient to stop interrupts from occuring. Therefore, also write
zeroes to the extended interrupt mask register when shutting down the
port.
This fixes the interrupt storm seen on the Pegasos board when shutting
down the interface.

Commit 66e63ffbc0 ("mv643xx_eth:
implement ->set_rx_mode()") cleaned up mv643xx_eth's multicast filter
programming, but broke it as well.
The non-special multicast filter table (for multicast addresses that
are not of the form 01:00:5e:00:00:xx) consists of 256 hash table
buckets organised as 64 32-bit words, where the 'accept' bits are
in the LSB of each byte, so in bits 24 16 8 0 of each 32-bit word.
The old code got this right, but the referenced commit broke this by
using bits 3 2 1 0 instead. This commit fixes this up.

This patch modifies how the tg3 driver handles device firmware.
The patch starts by consolidating David Woodhouse's earlier patch under
the same name. Specifically, the patch moves the request_firmware call
into a separate tg3_request_firmware() function and calls that function
from tg3_open() rather than tg3_init_one().
The patch then goes on to limit the number of devices that will make
request_firmware calls. The original firmware patch unnecessarily
requested TSO firmware for devices that did not need it. This patch
reduces the set of devices making TSO firmware patches to approximately
the following device set : 5703, 5704, and 5705.
Finally, the patch reduces the effects of a request_firmware() failure.
For those devices that are requesting TSO firmware, the driver will turn
off the TSO capability. If TSO firmware becomes available at a later
time, the device can be closed and then opened again to reacquire the
TSO capability.

In rare cases when an underrun occur, all macb buffers where consumed
and the netif_queue was stopped infinitely. This happens then the TGO
(transfer ongoing) bit in the TSR is set (and UND). It seems like
clening up after the underrun makes the driver and the macb hardware
end up in an inconsistent state. The result of this is that in the
following calls to macb_tx no TX buffers are released -> the
netif_queue was stopped, and never woken up again.
The solution is to disable the transmitter, if TGO is set, before
clening up after the underrun, and re-enable the transmitter when the
cleaning up is done.

A pointer to wm8400_regulator_probe is passed to the core via

.init sections are discarded. Otherwise (if also having HOTPLUG=y)
unbinding and binding a device to the driver via sysfs will result in an
oops as does a device being registered late.
An alternative to this patch is using platform_driver_probe instead of
platform_driver_register plus removing the pointer to the probe function
from the struct platform_driver.
