From f55c3ec42a97bca408f0208ec08e3382340c7be7 Mon Sep 17 00:00:00 2001 From: Yuval Shaia Date: Fri, 14 Dec 2018 08:05:49 -0800 Subject: [PATCH] IB/rxe: Reuse code which sets port state MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Same code is executed in both rxe_param_set_add and rxe_notify functions. Make one function and call it from both places. Since both callers already have a rxe object use it directly instead of deriving it from the net device.
