[PATCH 4.4 050/101] net: bgmac: Start transmit queue in bgmac_open

From: Greg Kroah-Hartman
Date: Mon Jul 03 2017 - 11:05:19 EST

4.4-stable review patch. If anyone has any objections, please let me know.


From: Florian Fainelli <f.fainelli@xxxxxxxxx>

commit c3897f2a69e54dd113fc9abd2daf872e5b495798 upstream.

The driver does not start the transmit queue in bgmac_open(). If the
queue was stopped prior to closing then re-opening the interface, we
would never be able to wake-up again.
