[Openib-windows] [PATCH] cl_timer

[Yossi Leybovich]

Fab

Attached patch for supporting nsec in timer stamp and provide way to get the
CPU freq
We use this in our performance tests (I hope that we upload them, to the
OpenIB in the near future)

(I left the cl_get_time_stamp_sec as is so we will not require to change old
code)
