From: Rasmus Villemoes <linux@xxxxxxxxxxxxxxxxxx>
Subject: linux/net.h: use unique identifier for each struct _ddebug
Changes on x86-64 later in this series require that all struct _ddebug
descriptors in a translation unit uses distinct identifiers. Realize
that for net_dbg_ratelimited by generating such an identifier via
__UNIQUE_ID and pass that to an extra level of macros.
No functional change.
