Subject: are IB port counters functioning over --IB-- with the RDMAoE  patch set?
Date: Thu, 27 May 2010 12:04:55 +0300	[thread overview]
Message-ID: <4BFE35B7.80009@voltaire.com> (raw)

Hi Eli, Vlad, 

Using some lab node here, I noticed that the IB port counters were not functioning over --IB-- with the RDMAoE patches present in an OFED drop named OFED-RDMAoE-1.5-rc6, see below.

Was/is this a known issue? if yes, was it fixed? is/was there an ofa bz case open for this? I didn't find such... I was told that under ofed 1.5.1 this doesn't happen, but I wanted to 1st clarify with you.

Or.
