Background: We have VS21 and SR1621 appliances connected over a pair of
dedicated switches to 5 Linux hosts. All Linux hosts use jumbo frames
and version 7.5 of the aoe driver. Each host has two interfaces for aoe
traffic, plugged into separate switches, as do the VS21 and SR1621.
We see about 0.2% packet loss regularly (judging from the rate of
retransmits), so I'm trying to understand why. We've already enabled
hardware flow control on all host and switch ports carrying aoe traffic.
