Driver did a poor job in managing its Tx queues: Sometimes it could stop tx queues due to link down condition in aq_nic_xmit - but never waked up them. That led to Tx path total suspend. This patch fixes this and improves generic queue management: - introduces queue restart counter - uses generic netif_ interface to disable and enable tx path - refactors link up/down condition and introduces dmesg log event when link changes. - introduces new constant for minimum descriptors count required for queue wakeup Signed-off-by: Pavel Belous <Pavel.Belous@aquantia.com> Signed-off-by: Igor Russkikh <igor.russkikh@aquantia.com> Signed-off-by: David S.
