[Linuxptp-devel] [PATCH v4 2/2] ptp4l: Allow advertisement of legacy PTP 2.0 protocol

2023-11-10 Thread Maciek Machnikowski
Some hardware can't properly timestamp packets with the new PTP header version 2.1. This patch adds legacy_ptp_ver config option that allows advertising of the legacy 2.0 protocol. Additionally, forcing PTP minor version to be nonzero causes interoperability issues with some legacy grandmasters.
