[Intel-wired-lan] ixgbe 4.2.1-k initiating reset due to tx timeout

[Vasiliy Tolstov]

Hi! I'm using 4.4.x stable kernel and have errors in SFP+ network card
on two servers.

filename:
/lib/modules/4.4.x/kernel/drivers/net/ethernet/intel/ixgbe/ixgbe.ko
version:        4.2.1-k
license:        GPL
description:    Intel(R) 10 Gigabit PCI Express Network Driver
author:         Intel Corporation, <linux.nics at intel.com>

Does Intel own driver already have fix for this issue? What i need to
do to fix this?
