I noticed that entering some vlan config, clicking "Update/Create", then clicking "Get Configuration" resulted in Tagged/Untagged/PVID displaying completely wrong data. It looks like the parisng in fetchVLAN() in vlan.js was just completely disconnected from the layout of the registers read by vlan_get() in rtl837x_port.c. Who knows how that happened. 1. Fix fetchVLAN() member/untag parsing: the old code read bits [9:0] as untagged and bits [10:19] as tagged, but the VLAN table register layout is members in [9:0] and untag in [19:10]. Now correctly derives tagged (member && !untag) and untagged (member && untag). 2. Add PVID to vlan.json response: PVID is stored per-port in separate PVID registers (RTL837x_PVID_BASE_REG), not in the VLAN table entry. The old code nonsensically tried to read it from bits [20:29] of the VLAN table. Add port_pvid_get() and build a pvid bitmask in send_vlan() so the JS can parse it correctly. 3. Remove auto-PVID logic from setC(): setC() is called by fetchVLAN() while it's loading existing config, and so this logic mangled the display of the existing config. Also, it doesn't make sense to auto-set the PVID for tagged members (PVID relates to untagged ingress.)
