- What I did
Add the feature to detect the Optical Module I2C bus recovery on Fishbone32, Fishbone48, and Phalanx. This prevent whole I2C bus lockup when a single optical module is hanging up.
- How I did it
Update the BSP driver to detect the bus stuck when doing I2C transfer.
If the bus stuck found, report error to kernel log. Then trying to recovery by resetting the I2C switch chip.
- How to verify it
SDAof SFP port1 to logic low.sfputil show eeprom -p Ethernet0sfputil show eeprom -p Ethernetxwith success.- Description for the changelog
