From 6fb5ff63b35b7e849cc8510957f25753f87f63d2 Mon Sep 17 00:00:00 2001 From: Horatiu Vultur Date: Sat, 26 Jul 2025 16:03:07 +0200 Subject: [PATCH] phy: mscc: Fix parsing of unicast frames According to the 1588 standard, it is possible to use both unicast and multicast frames to send the PTP information. It was noticed that if the frames were unicast they were not processed by the analyzer meaning that they were not timestamped. Therefore fix this to match also these unicast frames.
