[openib-general] [PATCH] vendor: identify rmpp mads

[Ofer Gigi]

Hi Hal,

RMPP mad can only sent in 4 kinds of mad:
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. 

Thanks

Ofer G.
