[PATCH] IB: userspace SRQ support
Add SRQ support to userspace verbs module. This adds several commands and associated structures, but it's OK to do this without bumping the ABI version because the commands are added at the end of the list so they don't change the existing numbering. There are two cases to worry about: 1. New kernel, old userspace. This is OK because old userspace simply won't try to use the new SRQ commands. None of the old commands are changed. 2. Old kernel, new userspace. This works perfectly as long as userspace doesn't try to use SRQ commands. If userspace tries to use SRQ commands, it will get EINVAL, which is perfectly reasonable: the kernel doesn't support SRQs, so we couldn't do any better.
