OK, did some testing, this re-init with link transition will happen on both
the 1G
drivers as well as ixgbe, its due to the stack/ioctl behavior when you do
the

So, what are you comparing this to that DOESN'T do this?? If this were to
be kept from happening I'm not sure where the responsible code would be
but I'm pretty sure its not in the driver :)
Long standing behaviour when adding aliases is that no interruption is
expected
on the main address. Now this probably doesn't happen too often, but
it'd be
really annoying to have services interrupted on systems that add and
subtract
aliases regularly. (I have had such systems on load-sharing setups)
Things could have changed and I suspect that it's harder and harder to
achieve as chips get smarter,
never the less, all the dumber chips I've used give this behaviour.

I will have to look into this, thanks for the report.

Please give me the exact steps that are performed that create this, not
sure what you mean by "manipulate ip aliases", if you mean ifconfig ix0
address,
then this has always caused a reinit of the device, the same behavior is
in the
1G devices. Or do you mean something else?
Oh, and while at it, pciconf -lv

Subject: Intel ix (X520) disconnects when manipulating ips?
Seems there's an issue with the intel ix driver which causes
it to bin connections when you manipulate ip aliases.
This causes issues on boot when jails start as it bins other
active sessions.
Is this a know issue?
Running 8.2-RELEASE amd64 here.
