It should still be 64 bytes.
struct netdev_tc_txq {
u16 count;
u16 offset;
};
struct netdev_tc_txq (4 octets) and TC_MAX_QUEUE = 16, so 4*16 = 64
+ struct netdev_tc_txq tc_to_txq[TC_MAX_QUEUE]; => 64 octets
+ u8 prio_tc_map[TC_BITMASK+1]; => 16 octets
All together 80 bytes this is certainly in the 512 unused bytes.Good ;) Considering a single TCP socket is larger than a net_device, I think its OK to not worry too much ;)
