Subject: [PATCH 3.15 062/109] r8152: fix r8152_csum_workaround function

3.15-stable review patch.  If anyone has any objections, please let me know.

------------------

From: hayeswang <hayeswang@...ltek.com>

[ Upstream commit a91d45f1a343188793d6f2bdf1a72c64015a8255 ]

The transport offset of the IPv4 packet should be fixed and wouldn't
be out of the hw limitation, so the r8152_csum_workaround() should
be used for IPv6 packets.
