[pve-devel] [RFC pve-network 4/6] sdn: dhcp: subnet: add DHCP options to subnet configuration

[DERUMIER, Alexandre]

I think that some common options could also be declared at subnet level
or even at zone level.

(I'm think about static routes for example, they could be defined at
subnet level,   maybe dnsserver,ntpserver could be defined at zone
level, ....)

to avoid to redefined them each time for each range.


So maybe be able to defined them at uppper level, and be able to
override them at range level.
