From cb013ea12cf71fe5ec2f7939909cec4491409724 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Fri, 14 Mar 2014 18:03:50 -0700 Subject: [PATCH] ibmveth: Don't receive packets when the napi budget == 0 Processing any incoming packets with a with a napi budget of 0 is incorrect driver behavior. This matters as netpoll will shortly call drivers with a budget of 0 to avoid receive packet processing happening in hard irq context. Signed-off-by: "Eric W. Biederman" Signed-off-by: David S.
