Re: Intel PRO/10GbE CX4? General 10Gb tips?

My understanding is that ixgb in CVS is quite far behind the vendor driver.

Unfortunately, for high performance 10GigE on FreeBSD the only options
worth looking at the moment are cxgb (Chelsio T3) and mxge (Myricom).
Chelsio is selling eval kits right now:
http://www.chelsio.com/evalkits.php

Myricom nominally sells their cards directly, but they've dropped both
a support request and a PO request from me, so I don't think its
worthwhile contacting them directly unless you're a large customer.
Bell Micro sells both the Chelsio and the Myricom cards.

at the driver in the source tree shows that it does some
hardware-specific checks for the SR adapter, because they "support two
different types of XPAK optics....." (ixgb_hw.c). There's no mention of
the CX4, and the dates on the source suggest they're from '04. I see
Intel has an updated version of this driver from '06 which explicitly
lists the CX4.

Are any of you familiar with these cards and, if so, do you know if the
6.2-RELEASE or later drivers will work with the CX4?

On a related note, do you have any suggestions for 10Gb hardware? I
lean towards the Intel stuff because, at least with the 1Gb stuff (and
aside from the weird and atypical em(4) problems earlier in 6-RELEASE),
the Intel stuff just works. That said, I'm open to suggestions for
other 10Gb stuff if you've got them.

Besides the tuning stuff discussed here before (around mid-December,
2006), are there knobs that I should tweak for ridiculously fast packet
capture?

As always, thanks in advance!
