| Subject: qed: iWARP - Fix tc for MPA ll2 connection |
| |
| [ 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") |
