[PATCH] ipv6: Revert optional address flusing on ifdown.

This reverts the following three commits: 70af921db6f8835f4b11c65731116560adb00c14 799977d9aafbf0ca0b9c39b04cbfb16db71302c9 f1705ec197e705b79ea40fe7a2cc5acfa1d3bfac The feature was ill conceived, has terrible semantics, and has added nothing but regressions to the already fragile ipv6 stack. Fi

[net-next PATCH 8/8] mlx5e: Fix IPv6 tunnel checksum offload

The mlx5 driver exposes support for TSO6 but not IPv6 csum for hardware encapsulated tunnels. This leads to issues as it triggers warnings in skb_checksum_help as it ends up being called as we report supporting the segmentation but not the checksumming for IPv6 frames. This patch corrects that an

[net-next PATCH 4/8] vxlan: Add checksum check to the features check function

We need to perform an additional check on the inner headers to determine if we can offload the checksum for them. Previously this check didn't occur so we would generate an invalid frame in the case of an IPv6 header encapsulated inside of an IPv4 tunnel. To fix this I added a secondary check to

[net-next PATCH 0/8] Fix Tunnel features and enable GSO partial for Mellanox adapters
