From: shemminger@linux-foundation.org Date: Fri, 26 Jan 2007 19:38:39 +0000 (-0800) Subject: sky2: software rx/tx stats X-Git-Tag: v2.6.21-rc1~92^2~31^2~45 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2bf56fe25cef2a7652f7b2ab37ac14a336c76c75;p=linux-2.6 sky2: software rx/tx stats Maintain packet statistics in software rather than hardware. This is slightly slower, but allows easier debugging of problems where packets are still being received by PHY but not being handled by hardware.
