Subject: [PATCH] [PATCH net-next] net: sfp: add quirk for OEM SFP+ONU-XGSPON
Date: Tue, 3 Nov 2026 01:18:42 +0000 [thread overview]
Message-ID: <20261103011849.181392-1-romit@romitsagu.com> (raw)
This XGS-PON ONU stick (vendor OEM, part SFP+ONU-XGSPON)
needs the same handling as other Potron-based modules. Without it,
the module fails to connect and the kernal shows these errors:
sfp sfp1: module transmit fault indicated
sfp sfp1: module persistently indicates fault, disabling
This module requires TX_FAULT/LOS behaviour and boot delay tuning.
Add a quirk using the existing sfp_fixup_potron.
