Subject: Similar functions in net/core/dev.c

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
