dapl: endpoint pending request count is wrong
The code assumes every cookie allocated during posting of
requests gets completed. This incorrect assumption results in
wrong pending count. Remove request_pending field and replace
with direct call, dapl_cb_pending, to provide accurate
data to consumer.
Add debug print if consumer overruns request queue.

dapl: Fix long delays with the cma provider open call when DNS is not configured on server.
Open call should default to netdev names when resolving local IP address for cma binding to match dat.conf settings. The open code attempts to resolve with IP or Hostname first and if there is no DNS services setup the failover to netdev name resolution is delayed for as much as 20 seconds.

At load time the symbol was resolved but with the

remove unnecessary assert from dapl_ep_free.
dat_ep_free must handle the case where a consumer calls
free in CONNECTED or DISCONNECT_PENDING states. After
free calls disconnect, there may be a pending event,
in which case the providers dapls_ib_qp_free will block
accordingly and handle pending events.

The OFA dapl provider is checking for incorrect return code
from rdma_bind_addr and rdma_listen calls. This causes an error
to be returned back to the consumer instead of correctly
incrementing the seed port and re-calling the OFA provider
until a valid port is issued. The seed value (1000) is also
incorrect and should start a non-privledged port (1024) to
avoid EPERM errors when seeding the starting port value.

Use inet_ntoa instead of open coding it. IP addresses were being
reversed on PowerPC.
On PowerPC the timebase ticks at a different frequency to the CPU.
dapltest currently assumes a 1:1 relationship, and gives bogus values
when scaling timebase to real time.
To fix this, look at the timebase field in /proc/cpuinfo instead. To
keep things consistent with x86, scale that value to MHz.

r10074: Added support for new ib verbs client register event. No extra processing required at the uDAPL

Fix some issues supporting create qp without recv cq handle or recv qp resources. IB verbs assume a

Fix some timeout and long disconnect delay issues discovered during scale-out testing. Added support
to retry rdma_cm address and route resolution with configuration options. Provide a disconnect call
when receiving the disconnect request to guarantee a disconnect reply and event on the remote side.
The rdma_disconnect was not being called from dat_ep_disconnect() as a result of the state changing
