[pve-devel] [PATCH 1/3] pass bridge value to vznetcfg script

[Alexandre DERUMIER]

>>And how do we get new value for vlan tag (if vlan changed)?

vlan tag is defined in bridge name:

vmbrXvY


(and also firewall enable|disable)

vmbrX(v(\d+))?(f)?


like this, it also don't break current user configs.
