Short description

Over UDP we call HarvestDestinationAddress() to get the real destination address via IP_PKTINFO, but this only sets the destination address, not the destination port. Therefore since
7cea4e3 the destination port was always 0 when bound to an "any" address.

Checklist

I have:

  • read the CONTRIBUTING.md document
  • compiled and tested this code
  • included documentation (including possible behaviour changes)
  • documented the code
  • added or modified regression test(s)
  • added or modified unit test(s)

Over UDP we call `HarvestDestinationAddress()` to get the real
destination address via `IP_PKTINFO`., but this only sets the destination
address, not the destination port. Therefore since
7cea4e39a78ef981ee461b49bbc193fa9903f56dit the destination port was always
0 when bound to an "any" address.
