Hi,
Doing HCA query (using ibv_devinfo on a system with two HCAs, memfull
Arbel and connectx, see details below), I have noticed that the value
of the max_qp_wr attribute is different, 64K on Arbel and 16K on connectx.
I thought that its possible that on the mlx4 case some filter function is
applied on the values returned by the FW, but I could not find an evidence
for that in the code - Roland, am I right and you return the FW values?
Jack, if this is not the case, can you confirm that the connectx supported
value is indeed 16K, is it FW depedent?
In mlx4 (and in other HCAs too) this value comes from the FW using the
command QUERY_DEV_CAP.
