Problem:

It's possible for updated NIC drivers to result in persistent network interface names changing after upgrade to Harvester v1.7.x, e.g. to add port numbers, so enp6s0f0 becomes enp6s0f0np0. This in turn breaks network configuration which is of course based on the original (pre-upgrade) interface names.

Solution:

Document the workaround for upgrades from v1.6.x to v1.7.0. Mention that the workaround is applied automatically when upgrading from v1.6.x to v1.7.1.

Bonus: mention that the workaround for another known v1.7.x upgrade issue is also automatically applied when upgrading to v1.7.1.
