Ahhh, thank you!
I didn’t realise this had changed and now the drivers are written with
full knowledge of the interface.
That is an overstatement but we know for sure a lot more about these
cards
then many other less open ones.
So that would make Intel Server NICs (i350 for example) some of the
best
1Gbe cards nowadays then?
They are well supported by OpenBSD as are many other server nics like
bge
and bnx. I would not call them best, when it comes to network cards it
seems to be a race to the bottom. All chips have stuff in them that is
just not great. em(4) for example needs a major workaround because the
buffersize is specified by a bitfield.
My view is more pessimistic, all network cards are shit there are just
some that are less shitty. Also I prefer to use em(4) over most other
gigabit cards.

Amen to that!! Especially Intel EIG44ET2 4-port GbE Nic.
