From 1b0ecb28b0cc216535ce6477d39aa610c3ff68a1 Mon Sep 17 00:00:00 2001 From: Vlad Yasevich Date: Tue, 30 Sep 2014 19:39:37 -0400 Subject: [PATCH] bnx2: Correctly receive full sized 802.1ad fragmes This driver, similar to tg3, has a check that will cause full sized 802.1ad frames to be dropped. The frame will be larger then the standard mtu due to the presense of vlan header that has not been stripped. The driver should not drop this frame and should process it just like it does for 802.1q.
