[pve-devel] [PATCH firewall] fix #2358: allow --<opt> in firewall rule config files

[Mira Limbeck <m.limbeck@proxmox.com>]

The docs mention --<opt> as valid syntax for firewall rules, but the
code that parses the .fw files only accepts -<opt>. To make it
consistent with the docs and the API, also accept --<opt>.

In addition allow 'proto' as option, not only '-p'.
