[PATCH 2/3] Remove in-code externs for some functions from net/core/dev.c

[Pavel Emelyanov <xemul@openvz.org>]

Inconsistent prototype and real type for functions may have
worse consequences, than those for variables, so move them
into a header.

Since they are used privately in net/core, make this file
reside in the same place.
