From 009dd872d753f854cf13c8334e0055092f539b38 Mon Sep 17 00:00:00 2001 From: Padmanabh Ratnakar Date: Tue, 10 May 2011 05:12:17 +0000 Subject: [PATCH] be2net: Handle error completion in Lancer In Lancer if a frame is DMAed partially due to lack of RX buffers, an error completion is sent with packet size as zero and num_recvd indicating number of used buffers. These buffers need to be freed and packet dropped. Signed-off-by: Padmanabh Ratnakar Signed-off-by: David S.
