Bits/sec rate fails to compute correct throughput after editing existing streams.

[zeus10000]

Steps to reproduce the issue:

• Create a new traffic stream with 1000 packet/sec. (Note: enter the packets/sec value without commas).
• Save the traffic stream.
• Edit the same traffic stream by increasing the packets/sec rate by adding a 0 to the trailing end (Note, this time the packets/sec value displays with comma).

You should see that the bits/sec rate displays as 0 rather than showing the correct traffic rate. Removing the comma resolves the issue and correct bits/sec value is displayed.
