Subject: alloc_netdev_mq() and multiqueues

Hello,
I have a short question about multiqueues  and I will appreciate if
somebody can answer shortly in 2-3 sentences.
When talking about multiqueues  I refer for example, to
http://nfws.edenwall.com/nfws_userday/David-Miller_Linux-Multiqueue-Networking.pdf,
alloc_netdev_mq() and friends.

1) Does an ordinary network driver code can be adjusted to use
multiqueues ? or do we need some
special hardware feature ?
2) How can I know if a certain device support multiqueus?\

3) Can anybody name some network cards which support  multiqueues?

Regards,
Kevin
