Subject[PATCH 4.16 38/81] net: sched: ife: signal not finding metaid
Date
4.16-stable review patch.  If anyone has any objections, please let me know.

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

From: Alexander Aring <aring@mojatatu.com>


[ Upstream commit f6cd14537ff9919081be19b9c53b9b19c0d3ea97 ]

We need to record stats for received metadata that we dont know how
to process. Have find_decode_metaid() return -ENOENT to capture this.
