In the above, several request messages come. From the SPEC, msn should
increase based on the number of request messages.
Hi Yanjun，
Current logic shows that posting a WQE on SQ increases SSN (SSN++) and
processing a WQE on responder successfully increases MSN (MSN++).
I think current SoftRoce doesn't implement the rule you metioned.
To be honest, the rule is not clear for me. when and how many
acknowledges of several request messages can we coalesce?
Hi, Jason Gunthorpe && Leon Romanovsky
In Mellanox RDMA NIC, how this rule is implemented?
Thanks a lot.

Can your commit handle the above case?
No.
