[Bug]: The random udp port in VxlanHashTest could be out of range

[congh-nvidia]

Issue Type

Bug Report

Description

The range of udp port is [0, 65535], but in the test the random range is [0, 65536], which could cause failure:

ValueError: While dissecting field 'sport': Incorrect type of value for field sport:
struct.error(''H' format requires 0 <= number <= 65535')
To inject bytes into the field regardless of the type, use RawVal. See help(RawVal)

That's a good catch! Also saw the same issue in our test.
