Subject[PATCH AUTOSEL 4.19 069/158] qed: iWARP - Fix tc for MPA ll2 connection
Date
From: Michal Kalderon <michal.kalderon@marvell.com>

[ Upstream commit cb94d52b93c74fe1f2595734fabeda9f8ae891ee ]

The driver needs to assign a lossless traffic class for the MPA ll2
connection to ensure no packets are dropped when returning from the
driver as they will never be re-transmitted by the peer.

Fixes: ae3488ff37dc ("qed: Add ll2 connection for processing unaligned MPA packets")
