When running the tests with this patch-set on OL6 I've encountered with 
failed tests
due to not supported ip options:

icmp-uni-basic 1 TINFO : - IPcomp [ transport ]
Error: argument "transport" is wrong: unknown

icmp-uni-basic 1 TINFO : - IPcomp [ tunnel ]
Error: argument "tunnel" is wrong: unknown

Have you tried running them on RHEL6?

It seems that iproute there requires some value passed after "... comp 
deflate ??? mode ..."
