[openib-general] [PATCH] Add -m option to ping pong programs to set path MTU

[Roland Dreier]

Thanks, I applied my own version of this.  Please make sure that the
svn tree still works for you.

(This patch was the one that pushed me over the edge with code
duplication in the pingpong examples, so I put the MTU switch
statement into a new pingpong.c file...)
