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

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

------------------

From: Florian Fainelli <f.fainelli@...il.com>

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.

Fixes: dd4544f05469 ("bgmac: driver for GBit MAC core on BCMA bus")
