Hi,

I was going through the mlx4 code for Secure Host and MAD_DEMUX feature.

I had a few queries..hoping that i can get these clarified.


If i understand correctly mlx4 codebase (mlx4_core/mlx4_en/mlx4_ib
drivers) take care of both RoCE and Infiniband adapters ( in both
dedicated and shared/SRIOV mode)


(1) After reading through the RoCE standard, I understood that Subnet
Management features are not supported in RoCE(they are part of
Infiniband)

(2) Also, as i understand MAD_DEMUX mechanism is used to control which
management traffic is passed to the host.

So by correlating these two( 1 & 2), am I correct in my understanding
when i say that MAD_DEMUX feature is not required to be
supported/implemented in Mellanox RoCE Drivers?

It is required only for Infiniband drivers?


I would be really thankful to get my understanding clarified.


Thanks so much....


Best Regards,
Bob
