Subject: ixgbe: Fix Tx Hang issue with lldpad on 82598EB
From: Jacob Keller <[email protected]>
commit 1eb9ac14c34a948bf1538bfb9034e8ab29099a64 upstream.
This patch fixes an issue with the 82598EB device, where lldpad is causing Tx
Hangs on the card as soon as it attempts to configure DCB for the device. The
adapter will continually Tx hang and reset in a loop.
