Add UDP ports configuration to IXIA traffic profile
- Implemented handling of UDP source and destination ports from IXIA traffic profile. - UDP ports can be defined as a single value or as a random range. Ports range is configured with two parameters 'fixed_bits' and 'mask_bits'. - For example '8-48' range definition will create a repeatable pattern of four values that fall within the range of 8 and 56.
