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.

When one end receives the packet it appears on its pair and vice
versa. The vxcan can be used for cross namespace communication.
- In opposite to vcan loopback devices the vxcan only forwards CAN
- frames to its pair and does *not* provide a local echo of sent
- CAN frames. To disable a potential echo in af_can.c the vxcan driver
- announces IFF_ECHO in the interface flags. To have a clean start
- in each namespace the CAN GW hop counter is set to zero.

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