It accelerates networking :)
It allows guests direct but safe access to a portion of the NIC, thus
avoiding going over the usual netback/netfront mechanism, and can result
in significant performance increase, particularly on receive. It's
aimed at 10Gbps.

Yes, you need a NIC with plugin drivers which support the architecture.
Right now there is just one option: the SMC TigerCard (available on
Amazon).

It was merged for 3.2.
Cheers,
Greg
