Subject: [PATCH 3.16 244/305] net: bgmac: Remove superflous netif_carrier_on()

3.16.37-rc1 review patch.  If anyone has any objections, please let me know.

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

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

commit 3894396e64994f31c3ef5c7e6f63dded0593e567 upstream.

bgmac_open() calls phy_start() to initialize the PHY state machine,
which will set the interface's carrier state accordingly, no need to
force that as this could be conflicting with the PHY state determined by
PHYLIB.

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