From fd47cc3fe1685379208ba05aaf3897548a25de3a Mon Sep 17 00:00:00 2001 From: Scott Murray Date: Tue, 20 Dec 2022 14:20:33 -0500 Subject: systemd-conf-canbus: Add link configuration Add a .link file to set the transmit queue length to 1000 for physical CAN devices. This matches the default used for vcan devices, and in testing fixes the transmit buffer overflows when running the simulator script against an interface.
