[OmniOS-discuss] infiniband

[Ian Kaufman]

I have had an issue with the Hermon driver and Mellanox ConnectX2 QDR
cards. On one system, I saw this in the log:

massive02-a hermon: [ID 492207 kern.info] hermon1: CQE RNR retry
counter exceeded

and the card went offline. Now, the interface does not even come up.
Three other identical systems are fine, as are two other systems with
the same card running Illumian 1.0a. I haven't found a way to reset
the RNR counter.
