Modification required for Broadcom based FlexLOM cards (530/533FLR)

[halmartin]

The HPE 530FLR-SFP+ and 533FLR-T cards are based on the Broadcom BCM57810. These cards do not work with the adapter without modification.

The KCORES FlexibleLOM Adapter appears to have a more accurate pinout of the FlexLOM connector:

The following modifications to the adapter make it compatible with the Broadcom-based FlexibleLOM cards:

1. Cut the trace between Vdet (to make pin B1 N/C)
2. Cut the trace connecting PERST to pin A1 (between the center/right solder pads)
3. Bridge the PERST left/center solder pads so PERST is connected to A14
4. Bridge 3.3V pad to pin A1
5. Connect 3.3V pad to A10/A11
6. Bridge GND between pins A4/A5/A6/A7/A8

With the above changes, the 533FLR-T adapter is working for me: lspci output
