ixgbevf: 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: - 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 Signed-off-by: Michał Mirosław <mirq-linux@rere.qmqm.pl> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
