| |
3.2.91-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Nathan Sullivan <nathan.sullivan@ni.com>
commit 49d52e8108a21749dc2114b924c907db43358984 upstream.
If the PHY is halted on stop, then do not set the state to PHY_UP. This ensures the phy will be restarted later in phy_start when the machine is started again.
Fixes: 00db8189d984 ("This patch adds a PHY Abstraction Layer to the Linux Kernel, enabling ethernet drivers to remain as ignorant as is reasonable of the connected PHY's design and operation details.")
