Hi Bob,
QCN (IEEE 802.1 based Ethernet congestion control mechanism) can apply
for IBoE traffic, in the same manner it would for FCoE, IP etc. Is
there a specific reason you wanted to apply the IB mechanism and not
use the Ethernet one? Yep, PFC is helpful.
Or.
Hi Or,
As I mentioned I did not pursue this. I was curious to see if I could
force a ConnectX device to slow down from a remote application. But
since the MADs have been crippled for IBOE there is no way to configure it.
