add patch for igc tx timeout issue
There were several reports about issues related to igc and tx timeout
and while the issue couldn't be reproduced locally, the hope is that
this fix Friedrich found will resolve the issue for the users. The
kernel versions in the reports would match with when 9b275176270e
("igc: Add ndo_tx_timeout support"), i.e. the one fixed by this
commit, landed.

Subject: [PATCH] igc: Fix Kernel Panic during ndo_tx_timeout callback
|
||||||
|
|
||||||
|
The Xeon validation group has been carrying out some loaded tests
|
||||||
|
with various HW configurations, and they have seen some transmit
|
||||||
|
queue time out happening during the test. This will cause the
|
||||||
|
reset adapter function to be called by igc_tx_timeout().
|
||||||
|
Similar race conditions may arise when the interface is being brought
|
||||||
|
down and up in igc_reinit_locked(), an interrupt being generated, and
|
||||||
|
igc_clean_tx_irq() being called to complete the TX.
|
||||||
|
|
||||||
|
When the igc_tx_timeout() function is invoked, this patch will turn
|
||||||
|
off all TX ring HW queues during igc_down() process. TX ring HW queues
|
||||||
|
will be activated again during the igc_configure_tx_ring() process
|
||||||
|
when performing the igc_up() procedure later.
|
||||||
|
|
||||||
|
This patch also moved existing igc_disable_tx_ring_hw() to avoid using
|
||||||
|
forward declaration.
