myri10ge: updates for 2.6.19

Jeff,

Here's 2 patches for myri10ge for 2.6.19.

1) use netif_msg_link
As you requested after I sent my first patch to make link status change reporting configurable, I reworked the code to use netif_msg_link. I sent this new version last week without getting any complains, so I hope it is ok to get merged now.

2) use multicast support in the firmware

Please apply.

Thank you,
Brice Goglin
