From mboxrd@z Thu Jan 1 00:00:00 1970 From: Andrew Boyer Subject: [PATCH 4/7] IB/rxe: Unblock loopback by moving skb_out increment Date: Fri, 18 Nov 2016 09:36:46 -0500 Message-ID: <1479479809-10798-4-git-send-email-andrew.boyer@dell.com> References: <1479479809-10798-1-git-send-email-andrew.boyer@dell.com> Return-path: In-Reply-To: <1479479809-10798-1-git-send-email-andrew.boyer-8PEkshWhKlo@public.gmane.org> Sender: linux-rdma-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org To: monis-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org, linux-rdma-u79uwXL29TY76Z2rM5mHXA@public.gmane.org Cc: Andrew Boyer List-Id: linux-rdma@vger.kernel.org skb_out is decremented in rxe_skb_tx_dtor(), which is not called in the loopback() path. Move the increment to the send() path rather than rxe_xmit_packet().
