diijkstra 95cbc1a2e0 TEG-S562: Correctly assign SFP
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.

# TrendNet TEG-S562
Following is documentation for unmanaged switch marked as `TEG-S563/EU H/W: V1.0R`.
Original software is running UART on 57600 baud rate. The software does not allow to
do anything fancy via serial. There is `IP` configuration which can be printed as well.
There might be also some flash upload procedure, but using SPI clamp in-board seems to
be easier method.
The memory chip is `Winbond W25Q16JV` with 16M-bit size.
## What does work
1. 2.5G ports on all advertised speeds.
2. SFP+ communication.
3. Serial, Web UI.
4. All LEDs
## Known issues
None.
## PCB
Manufacturer information be found [on the product page](https://www.trendnet.com/support/support-detail.asp?prod=105_TEG-S562).

### SW1 GPIO switch?
Not populated but looks like a switch for selecting
GPIO level. Missing resistors in place.
GPIO mapping unknown.
### S2 Reset ciruit
Not populated but looks like a button can be added on `S2` connector,
requires additional `R571` resistor which will pull signal to ground.
GPIO mapping unknown.

## Power supply
Input power is delivered via barell plug, `12V 1A` adapter was provided.
Board has two supply rails. `0.95` and `3.3` volt.
### `0.95` Core Voltage
Voltage is made by a `APW8713` (U3).
### `3.3` Voltage
Voltage is crated regulated by chip marked as `GoIAT` (U2).
## SFP SPI
There is separate clock and data lines for both SFP modules. MSDA/MSCK 0 and 1 need to be enabled.
SFP1 slot is connected to SPI0. SFP2 slot is connected to SPI1.
