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.
