Subject: [PATCH] mka: Pass full structures down to macsec drivers' packet
number ops
Clean up the driver interface by passing pointers to structs transmit_sa
and receive_sa down the stack to get_receive_lowest_pn(),
get_transmit_next_pn(), and set_transmit_next_pn() ops, instead of
passing the individual arguments.
