Looks like the SFP numbers are reversed, since GPIOs were mapped
to SFP numbers, the need to be reversed too. This fixes swapped
display of SFP stats on the webpage.
Added support for all leds on the device.
Stock port sets are slightly differently configured, where additional
LED0 on SET_0 and LED1&LED2 where configured for link/collisions/duplex.
This has not been reproduced as those lines are probably not connected
anywhere.
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
