ibv_detach_mcast(). I didn't really test them, so please let me know

The max_inline_data changes are now checked in. You can pass a
request for a max_inline_data value into ibv_create_qp() via
qp_attr.cap.max_inline_data, and the actual value (guaranteed to be at
least as much as you requested) will be returned in the same location.

The following patch will reject stale connection requests.
It also fixes a couple of minor error handling cleanup issues
found during testing, and fixes a bug handling a stale
connection reject message where the cm_id would access an
invalid timewait pointer.

Use of virt_to_phys looks wrong in sdp_recv and sdp_send.
Must not the DMA API be used to get the physical address
to be put in ib_sge?

Note that this change will need a coordinated change to OpenSM and some

once this patch is accepted.
