From: Andrew Morton Date: Fri, 31 Mar 2006 10:30:47 +0000 (-0800) Subject: [PATCH] "3c59x collision statistics fix" fix X-Git-Tag: v2.6.17-rc1~87 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0000754c27f07d5656eff17367c05dc4cfb7d965;p=linux-2.6 [PATCH] "3c59x collision statistics fix" fix The pre-2.6.16 patch "3c59x collision statistics fix" accidentally caused vortex_error() to not run iowrite16(TxEnable, ioaddr + EL3_CMD) if we got a maxCollisions interrupt but MAX_COLLISION_RESET is not set. Thanks to Pete Clements for reporting and testing.
