So, can someone give an estimation as to how soon that may be and how soon it may make it to 8-stable?  If it's going to be a while I may look into adding a card using a different driver to test.

igb(4) in HEAD would be more stable but I haven't had time to
experiment it. Last time I tried previous igb(4) driver which was
shipped with 8.0-RELEASE showed several issues under high network
loads as you might know. I have a patch which could be applied to
8.0-RELEASE or stable/8.

The patch would fix unresponsive system under high network load as
well as reducing number of interrupts. The patch also contains
bus_dma(9) and watchdog timeout fix.
