Yea CX4 will work, its the chipset that matters. But CX4 is short range and superseded, and by using SFP+ you can pick and choose your transceivers for fibre or CAT cabling etc.

Unfortunately on the Cisco part I don't SFP+.
I have XENPACK option only which give me 3 options:

SR ~ 3K GPL
LRM ~ 1.5K GPL (I can't find any LRM GBIC for Intel side)
CX4 ~ 600 GPL

I'd avoid CX4, you wont find a CX4 NIC working well with OpenBSD
nor would you want one tbh.. Stick with well known supported cards
for OpenBSD..

Thanks for all the replies Andy.

Are we totally sure about this?
I'm talking about Intel - CX4 support on OpenBSD with ix(4).

The manual page lists these:
            o   Intel 82598EB 10GbE Adapter (10GbaseCX4)
            o   Intel 82598EB Dual Port 10GbE Adapter (10GbaseCX4)
            o   Intel 82599EB 10GbE Adapter (10GbaseCX4)


CX4 should work fine but has mostly been replaced by
SFP+ direct attach/copper and 10GBase-T with new cards.
