Subject: hyperv: Fix a bug in netvsc_start_xmit()
From: KY Srinivasan <[email protected]>
[ Upstream commit dedb845ded56ded1c62f5398a94ffa8615d4592d ]
After the packet is successfully sent, we should not touch the skb
as it may have been freed. This patch is based on the work done by
Long Li <[email protected]>.
In this version of the patch I have fixed issues pointed out by David.
David, please queue this up for stable.
