Subject: [net-rfc 08/16] can: isotp: Explain PDU in CAN_ISOTP help text
Date: Mon, 19 Oct 2020 21:05:16 +0200
Message-ID: <20201019190524.1285319-9-mkl@pengutronix.de> (raw)
In-Reply-To: <20201019190524.1285319-1-mkl@pengutronix.de>

From: Geert Uytterhoeven <geert+renesas@glider.be>

The help text for the CAN_ISOTP config symbol uses the acronym "PDU".  However,
this acronym is not explained here, nor in Documentation/networking/can.rst.

Expand the acronym to make it easier for users to decide if they need to enable
the CAN_ISOTP option or not.
