2013-03-09tunneling: Add generic Tunnel segmentation.Pravin B Shelar1-3/+4
Adds generic tunneling offloading support for IPv4-UDP based tunnels. GSO type is added to request this offload for a skb. netdev feature NETIF_F_UDP_TUNNEL is added for hardware offloaded udp-tunnel support. Currently no device supports this feature, software offload is used. This can be used by tunneling protocols like VXLAN.

2013-02-15v4 GRE: Add TCP segmentation offload for GREPravin B Shelar1-1/+2
Following patch adds GRE protocol offload handler so that skb_gso_segment() can segment GRE packets. SKB GSO CB is added to keep track of total header length so that skb_segment can push entire header. e.g. in case of GRE, skb_segment need to push inner and outer headers to every segment. New NETIF_F_GRE_GSO feature is added for devices which support HW GRE TSO offload. Currently none of devices support it therefore GRE GSO always fall backs to software GSO.

2012-02-24net: Support RX-ALL feature flag.Ben Greear1-0/+2
This flag requests that network devices pass all received frames up the stack, even ones with errors such as invalid FCS (frame check sum). This will allow sniffers to see bad packets and perhaps give the user some idea how to fix the problem.

2012-02-24net: Support RXFCS feature flag.Ben Greear1-0/+2
When set on hardware that supports the feature, this causes the Ethernet FCS to be appended to the end of the skb. Useful for sniffing packets. Signed-off-by: Ben Greear <[email protected]> Tested-by: Aaron Brown <[email protected]> Signed-off-by: Jeff Kirsher <[email protected]>
2011-11-16net: remove NETIF_F_NO_CSUM feature bitMichał Mirosław1-3/+2
Only distinct use is checking if NETIF_F_NOCACHE_COPY should be enabled by default. The check heuristics is altered a bit here, so it hits other people than before. The default shouldn't be trusted for performance-critical cases anyway. For all other uses NETIF_F_NO_CSUM is equivalent to NETIF_F_HW_CSUM.

2011-11-16net: Define enum for net device features.Michał Mirosław1-40/+93
Define feature values by bit position instead of direct 2**i values and force the values to be of type netdev_features_t. Cleaned and extended from patch by Mahesh Bandewar <[email protected]>: + added netdev_features_t casts + included bits under NETIF_F_GSO_MASK + moved feature #defines out of struct net_device definition Signed-off-by: Michał Mirosław <[email protected]> Signed-off-by: David S.

2011-11-16net: split netdev features to separate headerMichał Mirosław1-0/+90
Move features definitions to separate header so that linux/skbuff.h won't need to include linux/netdevice.h after netdev_features_t is introduced. Signed-off-by: Michał Mirosław <[email protected]> Acked-by: Ben Hutchings <[email protected]> Signed-off-by: David S. Miller <[email protected]>
