One part is managing the need to setup multi-protocol ports on
boot. This seems like a general requirement for mlx4/5 so maybe it
should get some more common solution..

cxgb is a multi-kernel module driver, those scripts are an attempt to
load the other parts when the main driver is loaded. I'm not sure why
cxgb is special enough to get these files but mlx/etc are not.

I suspect it is old cruft because redhat/rdma.kernel-init handles
things uniformly on systemd environments.

I've been thinking we should patch the kernel to solve this problem
instead of using this ugly userspace solution..

Yes, pulling something like openibd into rdma-core is the idea here..

I think rdma-core is fine..

Maybe Leon's team will try to tackle some of this? It is complicated,
the RH scripts do quite a bit stuff :\

But this doesn't seem particularly urgent for Debian packaging, right?
