Date: Fri, 14 Mar 2014 17:57:59 -0700 From: ebiederm@...ssion.com (Eric W. Biederman) To: David Miller <davem@...emloft.net> Cc: eric.dumazet@...il.com, netdev@...r.kernel.org, xiyou.wangcong@...il.com, mpm@...enic.com, satyam.sharma@...il.com Subject: [PATCH net-next 01/16] bnx2x: 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.
