Subject: [net 13/27] can: isotp: Explain PDU in CAN_ISOTP help text
Date: Tue, 3 Nov 2020 23:06:22 +0100 [thread overview]
Message-ID: <20201103220636.972106-14-mkl@pengutronix.de> (raw)
In-Reply-To: <20201103220636.972106-1-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.
