If anyone has any objections, please let me know. ------------------ From: Anton Nayshtut [ Upstream commit f5e2dc5d7fe78fe4d8748d217338f4f7b6a5d7ea ] Before commit 3900f29021f0bc7fe9815aa32f1a993b7dfdd402 ("bonding: slight optimizztion for bond_slave_override()") the override logic was to send packets with non-zero queue_id through the slave with corresponding queue_id, under two conditions only - if the slave can transmit and it's up. The above mentioned commit changed this logic by introducing an additional condition - whether the bond is active (indirectly, using the slave_can_tx and later - bond_is_active_slave), that prevents the user from implementing more complex policies according to the Documentation/networking/bonding.txt.
