[ofa-general] IPoIB CM (NOSRQ) [PATCH 0]

[Pradeep Satyanarayana]

The patches to follow is a roll up of a couple of patches. These patches
have been tested against 2.6.23-rc1 kernel on ppc64 machines.

PATCH 1 -this is a combined patch of V8 and the misc patch along with 
some minor changes.

PATCH 2 -this enables a fall back to UD mode when there are not enough
resources to operate in CM mode. This is the same as the previous patch,
except that it has been updated for the newer kernel.

These patches do not address the following issues that will be worked upon
subsequently:

a) this does not handle the case when a packet is received on the receive 
queue of the tx_qp (RFC compliance)

b) Previous comment from Roland regarding event_handler in ipoib_cm_create_rx_qp()
I have reproduced the problem and a tests like netperf error out. Have not had a chance
to dig deeper to get at the root cause.
