DSA switch port vlan tagging - untagging

Try @lan4.1 notation, such as config interface 'vlan1000' option type 'bridge' option stp '1' option ifname 'eth0.1000 @gt95.1000 @gt96.1000 @gt97.1000 @gt98.1000' option proto 'none' option auto '1' option delegate '0'

WRT3200ACM and DSA

Hey Everyone! I'd like some help and to discuss a issue that has been in my head for some time. I'd like to know why Openwrt isn't using DSA instead of swconfig. I see that DSA is the chosen one upstream (linux kernel), and that this is disabled with a patch. I believe that I can revert this patch by myself, although I have few knowledge in these topics, so I'm here asking for help, opinions and hopefully to start a discusion about this! Thanks!
