Enquiry on GetTimerPeriod function in Ping.c

[twooi <tzy.way.ooi@intel.com>]

Hi,

I am enabling an UEFI ethernet driver in our platform. While I tried to
test the driver with ping command, I noticed that ping operation is
aborted due to the GetTimerPeriod function return a value 0.

In the function GetTimerPeriod in ping.c, the function will return the
value of StallCounter/RttTimerTick once it completed all the
operations. However, the value return in my platform is zero due to
StallCounter is having smaller value than RttTimerTick.

I am not sure what is the usage of GetTimerPeriod function and how it
works. The GetTimerPeriod function will return 0 if any of the
operation having an error during the execution. However, I suspect that
this function should not return 0 when StallCounter is having less
value than RttTimerTick? This is because the function actually did not
encounter any error. Please correct me if I m wrong.

Thank you

Best regards,
