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.

RDMA/cxgb3: Set the max_qp_init_rd_atom attribute.
Attribute max_qp_init_rd_atom is not getting set. Version 1.0.4 of
librdmacm now validates the user's requested initiator and responder
resources vs the max supported by the device. Since iw_cxgb3 wasn't
setting this attribute (and it defaulted to 0), all rdma_connect()s fail
if there are initiator resources requested by the app.
