Any comment?! is this going in for 3.13?
Note that without this series which enables flow-steering also on IB
ports, folks that have VPI environments, e.g dual ported HCA with one
port playing Ethernet and the 2nd port IB, can't enjoy flow-steering
since we have only one dev cap bit and the flow-steering patches that
went into 3.12 only implemented the feature for raw qps, so the driver
(mlx4) could enable the device capability when both ports are IB.
that was late nightish comment with a typos, to make it clear: the flow
steering patches
that were merge in 3.12 lack the support for IB UD QPs and hence the low
level driver could
enable the verbs level dev cap bit for flow steering only when both
ports are Ethernet.
Or.
