Message-ID: <20240605235155.116468-8-o-takashi@sakamocchi.jp>

Subject: [PATCH 07/11] firewire: core: add common inline functions to serialize/deserialize self ID packet
Within FireWire subsystem, the serializations and deserializations of phy
packet are implemented in several parts. They includes some redundancies.
This commit adds a series of helper functions for the serializations and
deserializations of self ID packet with a Kunit test suite.
