Subject: aoe: increase default cap on outstanding AoE commands in the network
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.
