[openib-general] [PATCH 0/3] iWARP CM

[Tom Tucker]

This is a repost of the iWARP CM and changes to CMA. This 
patch represents the modifications per the latest review from 
Sean and others. The most significant change is that the 
event handling model has been modified per Sean's recommendations 
and the iw_destroy_cm_id function will not return until the 
last reference on the cm_id has been removed. 

These changes have been tested with AMSO1100, Chelsio, and 
Mellanox HCA's. The testing consisted of multiple instances (3) of 
the krping application with an iteration count of 1 running in a 
loop in order to stress connection setup and tear-down. The test
platform consisted of two-way, hyper threaded, Intel platforms. 
Periodically the client and/or server side would be interrupted 
with ctrl-C and restarted to test abortive tear-down. 

This patchset defines the modifications to the CMA 
and header files to support iWARP devices. This 
patchset is a prerequisite of both the AMSO1100 
and Chelsio RNIC device drivers. 

The patchset consists of three patches:
        1 - Header files
        2 - Modifications to the CMA and uCMA
        3 - Implementation of the IW CM
