From 0c14e5ced264620284bd96f888614768c9bd0976 Mon Sep 17 00:00:00 2001 From: Ariel Elior Date: Wed, 17 Apr 2013 22:49:06 +0000 Subject: bnx2x: Fix status blocks configuration This fixes 2 issues regarding bnx2x's status blocks: 1. ethtool -c caused corruption of status blocks in FW RAM. 2. when using multi-CoS, the configuration of the timeout values of status blocks is incorrect, harming the coalescing of interrupts for such CoSs.
