This patch series is meant to allow us to get the best performance possible
for Mellanox ConnectX-3/4 adapters in terms of VXLAN tunnels.
The first few patches address issues I found when just trying to collect
performance numbers. Specifically I was unable to get rates of any more
than 1 or 2 Mb/s if I was using a tunnel that ran over IPv6. In addition I
found a few other items related to GSO_PARTIAL and the TSO_MANGLEID that
needed to be addressed.
The last 4 patches go through and enable GSO_PARTIAL for tunnels that have
an outer checksum enabled, and then enable IPv6 support where we can. In
my tests I found that the mlx4 doesn't support outer IPv6 but the mlx5 did
so the code is updated to reflect that in the patches that enable IPv6
support.

Alexander Duyck (8):
net: Disable segmentation if checksumming is not supported
gso: Only allow GSO_PARTIAL if we can checksum the inner protocol
net: Fix netdev_fix_features so that TSO_MANGLEID is only available with
TSO
vxlan: Add checksum check to the features check function
mlx4: Add support for UDP tunnel segmentation with outer checksum offload
mlx4: Add support for inner IPv6 checksum offloads and TSO
mlx5e: Add support for UDP tunnel segmentation with outer checksum offload
mlx5e: Fix IPv6 tunnel checksum offload
