Subject: [PATCH net-next 2/9] s390/qeth: remove skb_is_nonlinear() check on IQD
Date: Tue, 6 Jun 2017 14:33:43 +0200 [thread overview]
Message-ID: <20170606123350.13781-3-jwi@linux.vnet.ibm.com> (raw)
In-Reply-To: <20170606123350.13781-1-jwi@linux.vnet.ibm.com>
qeth doesn't advertise NETIF_F_SG for L3 IQDs. So trust the stack to
not hand us any nonlinear skbs, and remove an always-true condition.
With the fact that data_offset < 0 is no longer possible on IQDs,
apply a small cleanup to subsequent code.
