Reproducible igb related panic 11.0-ALPHA4

OS: FreeBSD 11.0-ALPHA4 #6 r302022

Hi,

Kernel panics within a few seconds with heavy network load. Using
"iperf -c another_host" is sufficient to induce the problem.  Setting
hw.igb.enable_msix=0 in loader.conf "solves" the problem.  Below is the
first few pages of crashinfo, + dmesg.  The problem occurs on 2 instances
of similar hardware (with same motherboards).

I was not able to reproduce this on my hardware. Can you use 'pciconf -lv' to find your card and get more specifics on which model of igb(4) it is?

I am guessing by the C224 chipset, that it is haswell-ish
