2017-08-17rsi: security enhancements for AP modePrameela Rani Garnepudi
Station id should be set in load key frame configured to device. For WEP mode, key is configured once from mac80211. This key is saved and configured to device every time a station is connected.

The MAC stats command takes a port ID, which doesn't exist on pre-ef10 NICs (5000- and 6000- series). This is extracted from the NIC specific data; we misinterpret this as the ef10 data structure, causing us to read potentially unallocated data.

2017-08-15ipv6: fib: Provide offload indication using nexthop flagsIdo Schimmel
IPv6 routes currently lack nexthop flags as in IPv4. This has several implications. In the forwarding path, it requires us to check the carrier state of the nexthop device and potentially ignore a linkdown route, instead of checking for RTNH_F_LINKDOWN. It also requires capable drivers to use the user facing IPv6-specific route flags to provide offload indication, instead of using the nexthop flags as in IPv4. Add nexthop flags to IPv6 routes in the 40 bytes hole and use it to provide offload indication instead of the RTF_OFFLOAD flag, which is removed while it's still not part of any official kernel release. In the near future we would like to use the field for the RTNH_F_{LINKDOWN,DEAD} flags, but this change is more involved and might not be ready in time for the current cycle.

2017-08-14mlxsw: spectrum_router: Add support for nexthop group consolidation for IPv6Arkadi Sharshevsky
Due to limited ASIC resources the maximum number of routes is limited by the nexthop resource. In order to improve the routing scale nexthop consolidation should be performed. This patch adds support for IPv6 neighbor consolidation. The hash value is calculated based on the nexthop set, by performing bitwise xor on the ifindexs of the nexthops, in a similar way to IPv4's kernel implementation. In case of collision a full match is performed between the sets which include address and ifindex comparison. Non gateway nexthop groups are not inserted to the hash table due to lack of nexthop device (ifindex).
