[pve-devel] [PATCH manager] ui: firewall: rule: maxlength for source and dest

[Aaron Lauterer <a.lauterer@proxmox.com>]

Limiting the length of the source and dest paramters helps to avoid
problems with iptables-restore which would not apply a rule if a
parameter is larger than the parameter buffer (1024)[0]. As the API is
already limiting this, we should also reflect that in the GUI and give
people a hint that IP sets are most likely the better approach.

This one "needs" the firewall patch 'fix #967: source: dest: limit length'

As always when it comes to messages, someone might have a better idea
how to phrase the maxLengthText.
