Subject: [PATCH 4/4] net: sfp: add mode quirk for GPON module Ubiquiti U-Fiber Instant
Date: Wed, 30 Dec 2020 16:47:55 +0100 [thread overview]
Message-ID: <20201230154755.14746-5-pali@kernel.org> (raw)
In-Reply-To: <20201230154755.14746-1-pali@kernel.org>
SFP GPON module Ubiquiti U-Fiber Instant has in its EEPROM stored nonsense
information. It claims that support all transceiver types including 10G
Ethernet which is not truth. So clear all claimed modes and set only one
mode which module supports: 1000baseX_Full.
This change finally allows to detect and use SFP GPON module Ubiquiti
U-Fiber Instant on Linux system.
EEPROM content of this SFP module is (where XX is serial number):
