I'm using AOC-STGN-i2S and can confirm it works perfect with ix(4)

ix(4) doesn't list the ES variant of the chip, and a quick grep through the 
driver source doesn't mention it explicitly, either.  Are any of you running 
this board under >= 6.0 ?

82599ES is the the "standard" two-interface chip, which is used in Intel X520 
and many other boards.


82599EB is also a two-interface chip, but with XAUI interface only (no 10 Gb/s 
serial capability for directly connecting to SFP+). I didn't see any boards 
which use it, but it would be suitable for XENPAK or X2 transceivers. So 82599ES 
is essentialy 82599EB + serdes.


There is also 82599EN, which is a single port 82599ES.


These data can be found in the 82599 datasheet. I am familiar with them, because 
five years ago I worked on a 82599ES board design, but sadly my company didn't 
mananage to finish it on time. There was suddenly more and more boards on the 
market, the prices dropped, and we abandoned the almost-completed project.

We're looking to buy some 10-gig SFP+ boards, and are eyeing up 
Supermicro's 2-port boards (listed as the 'Intel 82599ES - AOC-STGN-i2S').


ix(4) doesn't list the ES variant of the chip, and a quick grep through 
the driver source doesn't mention it explicitly, either.  Are any of you
