Hi Doug,
This patchset adds completion timestamping supports for verbs consumers.
Timestamping is used by applications in order to know when a WQE was
received/transmitted by the HW. The value is given is HCA hardware cycles,
but could be easily converted

Hi Doug,
This patchset adds completion timestamping supports for verbs consumers.
Timestamping is used by applications in order to know when a WQE was
received/transmitted by the HW. The value is given is HCA hardware cycles,
but could be easily converted as the hardware's core clock frequecny
