If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From foo@baz Fri Jun 2 09:29:55 JST 2017 From: Vlad Yasevich <vyasevich@xxxxxxxxx> Date: Tue, 23 May 2017 13:38:42 -0400 Subject: be2net: Fix offload features for Q-in-Q packets From: Vlad Yasevich <vyasevich@xxxxxxxxx> [ Upstream commit cc6e9de62a7f84c9293a2ea41bc412b55bb46e85 ] At least some of the be2net cards do not seem to be capabled of performing checksum offload computions on Q-in-Q packets. In these case, the recevied checksum on the remote is invalid and TCP syn packets are dropped. This patch adds a call to check disbled acceleration features on Q-in-Q tagged traffic.
