From d951f7250305adaea5f25398b70023681183d0cb Mon Sep 17 00:00:00 2001 From: Tom Herbert Date: Wed, 5 May 2010 18:15:21 +0000 Subject: [PATCH] forcedeth: Account for consumed budget in napi poll Repeated calls to nv_rx_process in napi poll routine do not take portion of budget that has been consumed in previous calls. Fix by subtracting the number of packets processed. Signed-off-by: Tom Herbert Signed-off-by: David S.
