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.
