The new cpsw-switch driver reserves VLAN 1 for internal use, which conflicts with the default network configuration of OpenWrt. Switch back to the older cpsw driver to make the network connection on the affected devices (BeagleBone Black and AM335x EVM) usable again. Signed-off-by: Jan Hoffmann <jan@3e8.eu>

Subject: ARM: dts: Use cpsw ethernet driver for some am335x devices
|
|
|
|
The new cpsw-switch driver requires a vid for every port which is
|
|
reserved for internal usage (defaulting to 1 and 2). As a result, some
|
|
network configurations are impossible, such as a bridge with
|
|
default_pvid of 1 (even if it is not vlan aware).
|
|
|
|
As a simple workaround, the ti,dual-emac-pvid property could be changed
|
|
to another value, but that would just shift the problem. Instead, switch
|
|
some devices back to the older cpsw ethernet driver.
|
|
|
|
(This patch is not suitable for upstreaming, it just makes the affected
|
|
devices in OpenWrt usable again with the default network config.)
