Yeah, maybe we should update chelsio kernel drivers instead of using
these strange modprobe files...

I'm not totally clear either, TBH. The overall topic is to move files
out of redhat/ and into the common directory. This requires removing
the redhat-isms and making sure the redhat solution is what we really
want upstream.
eg it seems rdma.cxgb[3]4.sys.modprobe is probably best done by patching
the kernel instead, not copying the modprobe files.
rdma.kernel-init does:
- Load extra ULP modules
* /etc/rdma/rdma.conf is not appropriate for Debian
* 'TECH_PREVIEW' is a RedHat concept
- Obsolete mttr/errata stuff. This is in the kernel now (delete it)
- Yet another go at loading extra driver kernel modules (move to
kernel)
- Something about SRIOV (?)
For ULP modules, I think we are loading too many by hand, again, the
kernel really needs fixing to autoload our stuff on first use. So, I
suggest a quick pass over that idea to see how much kernel code can be
fixed up.
So the stuff to move to common user space code might just be the port
configuration and sriov? But someone needs to study this entire topic
with a broad view including the kernel.
