Subject: [PATCH 0/2] Replacements for patches 2 and 7 in Big TCP series

This patch set is meant to replace patches 2 and 7 in the Big TCP series.
>From what I can tell it looks like they can just be dropped from the series
and these two patches could be added to the end of the set.

With these patches I have verified that both the loopback and mlx5 drivers
are able to send and receive IPv6 jumbogram frames when configured with a
g[sr]o_max_size value larger than 64K.

Note I had to make one minor change to iproute2 to allow submitting a value
larger than 64K in that I removed a check that was limiting gso_max_size to
no more than 65536. In the future an alternative might be to fetch the
IFLA_TSO_MAX_SIZE attribute if it exists and use that, and if not then use
65536 as the limit.
