Subject: [PATCH 2/4] net: sfp: allow to use also SFP modules which are detected as SFF
Date: Wed, 30 Dec 2020 16:47:53 +0100	[thread overview]
Message-ID: <20201230154755.14746-3-pali@kernel.org> (raw)
In-Reply-To: <20201230154755.14746-1-pali@kernel.org>

Some GPON SFP modules (e.g. Ubiquiti U-Fiber Instant) have set SFF phys_id
in their EEPROM. Kernel SFP subsystem currently does not allow to use
modules detected as SFF.

This change extends check for SFP modules so also those with SFF phys_id
are allowed. With this change also GPON SFP module Ubiquiti U-Fiber Instant
is recognized.
