Subject: [PATCH 19/63] NET: bcm63xx_enet: move phy_(dis)connect into probe/remove
|
|
|
|
Only connect/disconnect the phy during probe and remove, not during any
|
|
open/close. The phy seldom changes during the runtime, and disconnecting
|
|
the phy during close will prevent it from keeping any configuration over
|
|
a down/up cycle.
