Richard Gobert 3271f19bf7 net: gso: restore ids of outer ip headers correctly ...

Currently, NETIF_F_TSO_MANGLEID indicates that the inner-most ID can
be mangled. Outer IDs can always be mangled.

Make GSO preserve outer IDs by default, with NETIF_F_TSO_MANGLEID allowing
both inner and outer IDs to be mangled.

This commit also modifies a few drivers that use SKB_GSO_FIXEDID directly.
