Hi,
All these functions in net/core/dev.c are very similar.
__netdev_walk_all_upper_dev
netdev_walk_all_upper_dev_rcu
netdev_walk_all_lower_dev
__netdev_walk_all_lower_dev
netdev_walk_all_lower_dev_rcu
Can they be merged in one function? Are they a hot path?
Regards,
Vinicius

check when DX_DEBUG is set. This allows the
function to be used in other parts of the code.
Suggestions from: Andreas, Christoph, Nathan, Nick and Ted.

About the unreachable code in "if (0)" I think it could be removed.
It seems to be doing an extra check.

Changing favors concise usage.
