[PATCH 3/8] aoe: increase default cap on outstanding AoE commands in the network

From: Ed Cashin
Date: Thu Nov 22 2012 - 15:39:36 EST


The aoe driver will never be waiting for more than aoe_maxout AoE
commands from a given remote network port on an AoE target.
Increasing the cap increases performance. Users can tighten the
setting to reduce the amount of memory used for handling AoE
traffic or the network bandwidth used for AoE.
