Date: Wed, 15 Dec 2010 23:24:30 +0100 (CET)

Subject: [RFC PATCH 10/12] Intel net drivers: convert to ndo_fix_features
Private rx_csum flags are now duplicate of netdev->features & NETIF_F_RXCSUM.
Removing this needs deeper surgery.
Since ixgbevf doesn't change hardware state on RX csum enable/disable
its reset is avoided.
Things noticed:
- e1000, e1000e and ixgb have RX csum disabled by default
- HW VLAN acceleration probably can be toggled, but it's left as is
- the resets on RX csum offload change can probably be avoided
- there is A LOT of copy-and-pasted code here
