Also, I note your are runnign RELENG_7 and not RELENG_7_0 - any idea what changes there might have been in that ? One of the things I thought about trying was enabling polling, and also possibly turning off MSI and going back to regular interrupts. But these are just wild stabs in the dark as I am assuming that it is losing connectivity due to it losing signaling back to the kernel somehow.

I have applied those settings by hand just now, and will see if it helps. Not quite sure how to get them into rc.conf yet - I am using ipv4_addrs_re0="195.144.8.6/28 195.144.8.4/28" and am not sure how an ifconfig_re0 line might interact with it as yet. I dont want to edit rc.conf in case it reboots... -pete.
