Hi,

the problem here is that CONFIG_BRIDGE is set to 'm' (leading to
inclusion of the two functions above in the kernel module) while
CONFIG_ROCKER is set to 'y', requiring the functions at link time.

Is the attached patch sufficient to fix this?

Regards,

Andreas

Subject: [PATCH] net: ethernet: rocker: Add select to CONFIG_BRIDGE in Kconfig

In a configuration with CONFIG_BRIDGE set to 'm' and CONFIG_ROCKER
set to 'y', undefined references occur at link time:

This patch fixes these by selecting CONFIG_BRIDGE from CONFIG_ROCKER.
