From ff734ef4bca05fd5cd51b83d2e2a9f008b64f9a3 Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Tue, 29 Jan 2013 23:33:14 +0000 Subject: [PATCH] sfc: Wrap __efx_rx_packet() with efx_rx_flush_packet() The pipeline mechanism will need to change a bit for scattered packets. Add a wrapper to insulate efx_process_channel() from this.
