Subject: [PATCH] net: sfp: add potron quirk to the H-COM SPP425H-GAB4 SFP+ Stick
Date: Tue, 13 Jan 2026 18:29:57 -0500 [thread overview]
Message-ID: <20260113232957.609642-1-someguy@effective-light.com> (raw)
This is another one of those XGSPON ONU sticks that's using the
X-ONU-SFPP internally, thus it also requires the potron quirk to avoid tx
faults. So, add an entry for it in sfp_quirks[].
