From 94a9c981f7bdfdb6d092d1f92546bf61552c95d7 Mon Sep 17 00:00:00 2001 From: Julian Wiedmann Date: Tue, 6 Jun 2017 14:33:43 +0200 Subject: [PATCH] s390/qeth: remove skb_is_nonlinear() check on IQD 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.
