Added new `vlan show` command to dump current VLAN settings.
Supports printing PVID & ingress filtering per port.
Added new `ingress [p]<mode>` command to setup ingress filtering.
Added wrappers for enabling/disabling vlan filtering. Currently
not configurable, but state in console is read via ASIC registers.
Full VLAN dump & web support of new commands will be added later.
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.)
Currently 5 Bytes are used by the port and vlan configuration:
--------------------------------------------------------
; internal ram data
;--------------------------------------------------------
.area DSEG (DATA)
_port_ingress_filter_PARM_2:
.ds 1
_vlan_create_PARM_2:
.ds 2
_vlan_create_PARM_3:
.ds 2
They are used for passing parameters. Use __xdata to pass the
parameters instead.
RTL has up to 3 SCL pins and up to 4 SDA pins. Lets allow configuring
I2C with individual BUS numbers instead of 0/1 I2C.
This enables support for devices where SCL line is not shared between
SFP modules. MUX registry is now initialized depending on needed
pin function.
More over, some SFP pins require special MUX settings, lets initialize
those depending on SFP configuration. This adds TX Disable pin,
which right now is set to low at startup.
Caveats:
- We may still override MUX registry later
- Not sure how to handle invalid bus definitions
- Without SFP is it fine to *not* initialize anything?
- Do to RAM limitation we do inititalize output GPIO to low
This fixes handling of the SFP ports in the stat command.
The output of the command now is for physical ports, which however are
not shown in sequence.
