Subject: [PATCH] net: phy: b53: switchdev driver for Broadcom BCM53xx switches
BCM53xx is series of Broadcom Ethernet switches that can be found in
various (mostly home) routers.
They are quite simple switches with mainly just support for:
1) Tagging incoming packets (PVID)
2) Untagging outgoing packets
3) Forwarding all packets across a single VLAN
This driver is split into common code (module) and bus specific code.
Right now only PHY (MDIO) support is included, other could follow after
accepting this driver. It was successfully tested on BCM4706 SoC with
BCM53125.
You could notice it's yet another try of submitting b53 driver. This
time it was modified to use recently introduced switchdev API which
hopefully make it possible to accept it mainline.
Signed-off-by: Rafał Miłecki <zajec5@...il.com>
---
Example usage. My BCM4706 router has switch with 6 ports:
0: WAN port
1-4: LAN ports
8: CPU connected port (on-SoC Ethernet device)
I decided to use VLAN 1 for WAN and VLAN 2 for LAN. I was able to
successfully configure it using:
bridge vlan add vid 1 dev sw0p1 pvid untagged
bridge vlan add vid 1 dev sw0p2 pvid untagged
bridge vlan add vid 1 dev sw0p3 pvid untagged
bridge vlan add vid 1 dev sw0p4 pvid untagged
bridge vlan add vid 1 dev sw0p8
bridge vlan add vid 2 dev sw0p0 pvid untagged
bridge vlan add vid 2 dev sw0p8
