bonding: Bonding driver does not consider the gso_max_size/gso_max_segs setting of slave devices.
Patch sets the lowest gso_max_size and gso_max_segs values of the slave devices during enslave and detach. Signed-off-by: Sarveshwar Bandi <sarveshwar.bandi@emulex.com> Acked-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
