A new option '--kmod-options' is added which takes a string which will be
passed to modprobe when loading the module.
This for instance allows easy override of things like the random seed when
trying to reproduce failures.
Anyway we can simply extend the option parsing locally? (Just find it
unsightly to have test specific options in libigt.)
Well.. it is not test specific but kmod specific but point still stands.
Stashing argc/argv in igt_subtest_init_parse_opts() and then being able
to run getopts inside igt_main {}?
Yep, I didn't know we have this already.
I also had in mind an env for module options, which may be also useful
for the module reloading and autoloading.
In that case, since modprobe(8) supports MODPROBE_OPTIONS, we could
perhaps emulate that in igt_kmod? Or add support directly to libkmod?
With either we wouldn't even need the command line pass through. Adding
Lucas for an opinion since kmod seems to be his baby.

Tvrtko
