Subject: [PATCH 1/1] net: sfp: add support for HALNy GPON SFP
|
|
|
|
Add a quirk for the HALNy HL-GSFP module, which appears to have an
|
|
inverted RX_LOS signal, and maybe uses TX_FAULT as a serial port
|
|
transmit pin. Rather than use these hardware signals, switch to
|
|
using software polling for these status signals.
