Subject: [PATCH 2/5] net: ethernet: stmicro: stmmac: first disable all queues
and disconnect in release
Disable all queues and disconnect before tx_disable in stmmac_release to
prevent a corner case where packet may be still queued at the same time
tx_disable is called resulting in kernel panic if some packet still has
to be processed.
