Subject: [PATCH 07/19] net: dsa: mxl862xx: warn about old firmware default PCE
|
|
rules
|
|
|
|
Firmware versions older than 1.0.80 install global PCE rules at
|
|
boot that redirect link-local frames (BPDUs, LLDP, LACP) to port 0
|
|
(the on-chip microcontroller) instead of the DSA CPU port. With
|
|
port 0 disabled under DSA, these rules silently drop matching
|
|
traffic.
|
|
|
|
Log a warning when old firmware is detected so users know to update.
