Hello,
I just imported ix(4), a driver for the Intel 82598EB 10 Gigabit

Ethernet adapters. It is based on Intel's ixgbe FreeBSD driver, with

many local changes for OpenBSD.
The driver is fully-operational and survived some long-time tests, I

had to work on borrowed hardware from another company since Intel

didn't provide us any cards. It is currently not sure how to maintain

the driver in the future without having cards in the project.
John Ronciak from Intel told me told me that they don't have more

cards to give away. It is purely a business case issue; a lot of

customer have asked for FreeBSD, they got two cards, but nobody asked

for an OpenBSD driver. He told me that they're doing the right for

their customers. But of course I could still buy them on the open

market.
Anyway, have fun with ix(4), it may become more common on the market.
