...and it is stable for you ? I will defintely go and turn these off in
that case! 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. WHich
is a total guess.

This is extermely interesting! 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...
