zigbee: Adjust pedantic LinkCost check and Malformed RREP command

Alberto Gallegosrequested to merge
shattered.feelings/ns-3-dev:zigbeeRREPfix into master

This MR introduces 2 changes:

  • It adjust the existing pedantic requirement of a minimum LinkCost during the Network Joining process. A linkcost of 3 is recommended but after some realistic test, this requirement causes the network join to fail 1 out 3 times. This makes it very unreliable. Therefore, I have made the adjustment to take any network as long as it fulfill the remaining requirements and favor the network with the lowest LinkCost.

  • The second change fixed the current malformed RREP command header. This command has a missing portion (Command Options) that is not serialized with the rest of the header. This was detected in Wireshark during a recent test.

Changes and release note will be added before the merge.
