Does this work? Has anyone seen it work?
I'm testing it on a pair of mlx4 MT25418 and I'm trying to get down to
2.5Gbps and I can't see any effect from twiddling the static_rate AH
attribute for an RC QP. The value seems to be working, I put 30 in to
a ibv_modify_qp with IBV_QP_AV and 2 comes back (the max, it looks
like..)
Anyone know?
Jason

Static rate is not implemented on ConnectX
