[ofa-general] [PATCH 2.6.24] RDMA/cxgb3: Set the max_qp_init_rd_atom attribute.

[Steve Wise]

Hey Vlad,

Can you pull this in for  1.3 beta?  Roland has merged it for 2.6.24, so 
it can be removed if we rebase and get it that way, but rping and most 
other rdma/iwarp apps are dead over chelsio without this fix.

Please pull from:

git://git.openfabrics.org/~swise/ofed-1.3 stevo

Thanks,

Steve.
