[ofa-general] [PATCH ibverbs] Do not use enum object types for bitfields

[Roland Dreier]

Thanks... I guess we can take a stab at doing this and see if anyone
breaks because of it.

I do notice that this patch doesn't update the man pages and therefore
leaves them out of sync with the actual code.  And that makes me notice
that by going from "enum ibv_foo foo" to "int foo" we lose the nice
self-documenting property of the API that it tells you what set of flags
are supposed to be used there.  I guess we should make sure that at
least all the interfaces in verbs.h used by applications (as opposed to
driver stuff in driver.h) document what enum contains the flags that go
into each parameter.
