[openib-general] Re: [PATCH] [CM] 1/2 Fix CM redirection

[John Kingman]

Second attempt; sent this last night.  I apologize if it is a duplicate.

Here's an updated change.  Took the suggestions and it should be cleaner.  
Not the be-all, end-all answer for redirection, of course, but it works 
for my situation.  

Any chance of inclusion as an interim fix?
