Revision e5c0bc4ff5b067075e477e983e9d9007e0a920c9 authored by Frank Jungclaus on 30 November 2022, 20:22:42 UTC, committed by Greg Kroah-Hartman on 14 December 2022, 10:37:30 UTC
[ Upstream commit 918ee4911f7a41fb4505dff877c1d7f9f64eb43e ]
We don't get any further EVENT from an esd CAN USB device for changes
on REC or TEC while those counters converge to 0 (with ecc == 0). So
when handling the "Back to Error Active"-event force txerr = rxerr =
0, otherwise the berr-counters might stay on values like 95 forever.
Also, to make life easier during the ongoing development a
netdev_dbg() has been introduced to allow dumping error events send by
an esd CAN USB device.
