From 8581145f39c39b00cd1b6a2dcb4ce5bf7d8d6070 Mon Sep 17 00:00:00 2001 From: Alexander Duyck Date: Sat, 23 Jan 2010 01:35:00 -0800 Subject: igb/igbvf: cleanup exception handling in tx_map_adv After removing the skb_dma_map/unmap calls the exception handling in igb_tx_map_adv is not correct. The issue is that the count value was not being correctly handled so as a result we were not rewinding the ring as back as we should have been.

The following patch fixes the check for IPv6 GSO packet in Intel ethernet drivers to use skb_is_gso_v6(). SKB_GSO_DODGY is also set when packets are forwarded from a guest.
