Subject: [PATCH net-2.6] cdc_ether: Partially revert "usbnet: Set link down initially ..."
Date: Thu, 28 Jan 2010 23:18:44 +0000 [thread overview]
Message-ID: <1264720725.373.550.camel@localhost> (raw)
In-Reply-To: <omZ8aBZReyD.A.rz.COlSLB@chimera>
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.
