2016-01-10ipv4: Namespecify tcp_keepalive_probes sysctl knobNikolay Borisov5-10/+12

2016-01-10ipv4: Namespaceify tcp_keepalive_time sysctl knobNikolay Borisov5-10/+14
Different net namespaces might have different requirements as to the keepalive time of tcp sockets. This might be required in cases where different firewall rules are in place which require tcp timeout sockets to be increased/decreased independently of the host.

It may happen that we get notification for FDB entry for object (port, lag, vport), which does not exist. Currently we ignore that, which only causes this being re-sent in next notification. The entry will never disappear. So get rid of it by simply removing it using SFD register.

2016-01-09batman-adv: increase BLA wait periods to 6Simon Wunderlich1-1/+1
If networks take a long time to come up, e.g. due to lossy links, then the bridge loop avoidance wait time to suppress broadcasts may not wait long enough and detect a backbone before the mesh is brought up. Increasing the wait period further to 60 seconds makes this scenario less likely.

2016-01-08ixgbe: Make ATR recognize IPv6 extended headersMark Rustad1-10/+37
Right now ATR is not handling IPv6 extended headers, so ATR is not being performed on such packets. Fix that by skipping extended headers when they are present. This also fixes a problem where the ATR code was not checking that the inner protocol was actually TCP before setting up the signature rules. Since the protocol check is intimately involved with the extended header processing as well, this all gets fixed together.
