Subject: [PATCH 07/11] can: lin: Add special frame id for rx offload config
Date: Mon, 22 Apr 2024 08:51:10 +0200 [thread overview]
Message-ID: <20240422065114.3185505-8-christoph.fritz@hexdev.de> (raw)
In-Reply-To: <20240422065114.3185505-1-christoph.fritz@hexdev.de>
A LIN bus supports up to 64 identifiers in one byte. This commit adds a
special frame ID, beyond the actual LIN identifiers, for signaling RX
offload configuration requests. This ID will be utilized in future LIN
enhancements to the CAN broadcast manager.
