documentation seems a bit unclear

hi,

this part of the documentation seems unclear for https://www.cni.dev/plugins/current/main/bridge/

vlan (int, optional): assign VLAN tag. Defaults to none.
preserveDefaultVlan (boolean, optional): indicates whether the default vlan must be preserved on the veth end connected to the bridge. Defaults to true.
vlanTrunk (list, optional): assign VLAN trunk tag. Defaults to none.

how to :
– allow packets for/from a vlan and keep incoming tagged aka bridge vlan add vid x dev x ?
– allow packets for/from a vlan and untag incoming aka bridge vlan add vid x dev x untagged ?
– force outgoing untagged packet to be tagged aka bridge vlan add vid x dev x pvid ?
– allow packets for/from a vlan and untag incoming and force outgoing untaged aka bridge vlan add vid x dev x pvid untagged ?

I hope you will understand my issue is not about understanding vlans or linux, but about understanding the doc for transposing a wellknown standard linux command to manage bridges and vlans to a cni configuration

@nathanaelle, please have a look at containernetworking/cni.dev#134

there is also another issue about the same. #939
