Subject: [PATCH] cdc_ether: Partially revert "usbnet: Set link down initially ..."
|
|
|
|
commit 71cc1fa9f2d71eb2eba9b8e71e27cff9863e55f3 upstream.
|
|
|
|
Commit 37e8273cd30592d3a82bcb70cbb1bdc4eaeb6b71 ("usbnet: Set link down
|
|
initially for drivers that update link state") changed the initial link
|
|
state in cdc_ether and other drivers based on the understanding that the
|
|
devices they support generate link change interrupts. However, this is
|
|
optional in the CDC Ethernet protocol, and two users have reported in
|
|
<http://bugzilla.kernel.org/show_bug.cgi?id=14791> that the link state
|
|
for their devices remains down. Therefore, revert the change in
|
|
cdc_ether.
