[PATCH net-next v1 0/9] selftests: rds: Add ROCE support to rds selftests

[Allison Henderson <achender@kernel.org>]

Currently the rds selftests only tests the tcp transport.  This means
most of rds_rdma.ko has no testing coverage.  This series refactors the
rds self tests to add an rdma option when running tests.  When used,
the test creates a pair of ROCE interfaces to run the payloads through.

Most of this set is refactoring the existing test.py module.  Since most
of this code is one long procedure, it is difficult to modularize it
without creating a lot of pylint complaints about lengthy functions
with too many variables or branches.  The first seven patches address
this by breaking down test.py into helper functions.  After we have
modularized the send/recv packet logic, we introduce the new ROCE
equivalent network configurations, add the new command line flags to
build and run the test with rdma support.  

Questions, comments and feedback appreciated!

Thanks everyone!
Allison
