net: allow gro_max_size to exceed 65536
Allow the gro_max_size to exceed a value larger than 65536.
There weren't really any external limitations that prevented this other
than the fact that IPv4 only supports a 16 bit length field. Since we have
the option of adding a hop-by-hop header for IPv6 we can allow IPv6 to
exceed this value and for IPv4 and non-TCP flows we can cap things at 65536
via a constant rather than relying on gro_max_size.
[edumazet] limit GRO_MAX_SIZE to (8 * 65535) to avoid overflows.
