10 GbE network drivers

[Brook Milligan <brook%nmsu.edu@localhost>]

Does anyone have recommendations on 10 GbE network interfaces that are
well supported by NetBSD drivers?  I am aware that there are drivers
for the Chelsio N320E card, but as far as I can tell there is no
documentation, which makes me nervous.  Would the Intel 82597EX 10
Gigabit Ethernet (dge(4)) be a better choice?

Thanks for your help.

Cheers,
Brook
