This is based on timing and the double invocation of some routines. The phy_exit() call needs to be run after the network device has been closed and unregistered from the system. Also, the phy_exit() does not need to invoke phy_stop() since that will be called as part of the device closing, so remove that call. Signed-off-by: Tom Lendacky Signed-off-by: David S.
