Hi Yongseok,

Only discussing here question, other comments are address, as I don't
have any objection I'll make the modification for them.

By the time it was as this Mellanox OFED was the latest GA 4.3-3.0.2.1,
this is no more the case today as it cannot be downloaded anymore. A
verification is still necessary.  If the issue is not present anymore
I'll remove the comment with the test.

Already added, the same issue occurs also with UDP/TCP.  If the user
uses some protocol it must match the following layer, otherwise its
request won't be respected which is a bug.
