OK, so i think you guys have posted some patches recently for support on 
regular adopters? So can i pull in that git tree? if so do you have a private 
tree or the net-next tree? I dont intend to use IB or iWARP in vm as i dont 
have the adopter in the physical machine. So i can only test with regular 
ethernet cards.

but if iam to choose a git tree kernel with regular card support shouldnt i go 
with development tree for rds-tools?
