Description
Use proper multiplier while converting HCA core clock frequency into Hz.
What
Fix IB clock converter inaccuracy
Why ?
Invalid value for hca core clock frequency was used in time_converter_ib_ctx::calculate_delta.
How ?
We used hca_core_clock for clock conversion from HW timestamp to system clock. But the value for hca_core_clock variable is converted from device capabilities as it's in MHz (multiplied to 1000000=USEC_PER_SEC). That's look wrong because ibv_device_attr_ex.hca_core_clock is in Khz.
