[openib-general] GRH Validation on Incoming Packets

You're exempt from checking it. Check out IB spec:
C8-19: The network layer shall silently discard, with the exception of
adjusting any applicable management counters specified elsewhere in this
specification, packets that meet any of the following conditions:

* Value of IPVer is not 6.

* The value of DGID does not equal one of the GID values assigned to the
port that received the packet.

Hi,

I have a question about whether any GRH validation is done on incoming GSI
packets which contain GRHs. If so, is the IP version field validated or does
that need to be done by the MAD layer or clients (like PMA) ?

Thanks.
