[openib-general] [PATCH] OpenSM - osm_vendor_mlx_svc.h fix for branch1.0

[Yael Kalka]

Hi Hal,

Attached is a patch for branch 1.0, for the osm_vendor_mlx_svc.h that
was applied on the trunk but not on the branch 1.0.

OpenSM/osm_vendor_mlx_svc.h: Identify RMPP MADs

RMPP mads can only sent in 4 MAD classes:
1. IB_MCLASS_SUBN_ADM 
2. IB_MCLASS_DEV_MGMT 
3. BIS 
4. DevAdm

If the packet is not 1 or 2 - the mad is not checked and returned in advance as not a rmpp packet. 

Since 3,4 are not management classes (see 13.4.4 page 720 in the spec),
I don't know whether they are defined as constants or not, so I didn't
handle them.
