Subject: [PATCH v2 05/15] IB/srp: Skip host settle delay
Date: Fri, 28 Jun 2013 14:50:37 +0200	[thread overview]
Message-ID: <51CD869D.2090006@acm.org> (raw)
In-Reply-To: <51CD856A.3010102-HInyCGIudOg@public.gmane.org>

The SRP initiator implements host reset by reconnecting to the SRP
target. That means that communication with the target is possible
as soon as host reset finished. Hence skip the host settle delay.
