Subject[30/35] net: filter: Use WARN_RATELIMIT
2.6.32-longterm review patch.  If anyone has any objections, please let us know.

------------------


From: Joe Perches <joe@perches.com>

[ Upstream commit 6c4a5cb219520c7bc937ee186ca53f03733bd09f ]

A mis-configured filter can spam the logs with lots of stack traces.

Rate-limit the warnings and add printout of the bogus filter information.
