Subject: [PATCH net] ibmvnic: Wait until reset is complete to set carrier on
Date: Tue, 13 Feb 2018 15:32:50 -0600 [thread overview]
Message-ID: <1518557570-31845-1-git-send-email-tlfalcon@linux.vnet.ibm.com> (raw)
Pushes back setting the carrier on until the end of the reset
code. This resolves a bug where a watchdog timer was detecting
that a TX queue had stalled before the adapter reset was complete.
