net: Add netif_get_gro_max_size helper for GRO

Browse source

Add a small netif_get_gro_max_size() helper which returns the maximum IPv4
or IPv6 GRO size of the netdevice.

We later add a netif_get_gso_max_size() equivalent as well for GSO, so that
these helpers can be used consistently instead of open-coded checks.
