Sean,
Here is a to fix a bug in service_id/service_mask
handling in CM.
Previously, if you tried to listen on service_id:
service_mask of 0x00:0x0F, followed by a listen
on 0xF0:0xF0, the second listen would fail because
the two ranges overlap (0xF0 appears in both ranges).
But, if you tried the

This patch keeps a reference count on the doorbell pages that are
mapped into userspace for direct verbs access. This prevents a
buggy/malicious app from closing its context but keeping a doorbell
page mapped, and then improperly accessing the doorbell page after it

I dont see why, the new input param to dat_rmr_bind (lmr_handle) come
in order that we will be able to remove the hash table so this is one

There's no reason it shouldn't work with the latest code. I've not
tried it, but the only reason that mthca would not provide the FMR
functions would be if the FW is burned with

This patch removes the last remaining typedef enums (minus bool
which /might/ justify it).

Itamar,
Can you seperate the RMR api change and hash table removal into a
seperate patch?
Merging the HCA and IA code into the dapl_ia.[ch] files doesn't feel
right to me. I think of the HCA as a DAT object just like IAs, EPs,
LMRs, etc, and hence it should have its own file.

[IPoIB] Add support for MTU module parameter. This is so there can be a
non default MTU at boot up if the administrator so desires (prior to
being able to invoke ifconfig).
