Subject: [PATCH 0/2] fix kernel crash with macvtap on top of LRO
Date: Thu, 7 Feb 2013 01:02:38 +0200	[thread overview]
Message-ID: <cover.1360191528.git.mst@redhat.com> (raw)

At the moment, macvtap crashes are observed if macvtap is attached
to an interface with LRO enabled.
The crash in question is BUG() in macvtap_skb_to_vnet_hdr.
This happens because several drivers set gso_size but not gso_type
in incoming skbs.
The following patches fix this for
Additionally, cbf1de72324a8105ddcc3d9ce9acbc613faea17e is required
to fix this for broadcom - would it make sense to cherry-pick
this patch into 3.8?

I tested that the patch fixes the crash for ixgbe but
don't have qlogic hardware to fix.  I also only tested TCP.

Feedback wellcome.

  ixgbe: fix gso type
  qlcnic: set gso_type
