Subject: [PATCH net 01/19] can: vxcan: Kconfig: fix description stating no local echo provided
Date: Thu, 16 Jul 2026 17:47:26 +0200	[thread overview]
Message-ID: <20260716155528.809908-2-mkl@pengutronix.de> (raw)
In-Reply-To: <20260716155528.809908-1-mkl@pengutronix.de>

From: Alexander Hölzl <alexander.hoelzl@gmx.net>

The Kconfig description of the vxcan kernel module erroneously states the
the vxcan interface does not provide a local echo of sent can frames.
However this behavior changed in commit 259bdba27e32 ("vxcan: enable local
echo for sent CAN frames") and vxcan interfaces now provide a local echo.

Change the description of the vxcan module in the Kconfig to reflect this
change.

 	  This driver can also be built as a module.  If so, the module
 	  will be called vxcan.
