[dpdk-dev] [PATCH 3/5] net/sfc/base: reject automatic filter creation by users

[Andrew Rybchenko]

From: Igor Romanov <igor.romanov at oktetlabs.ru>

The automatic filter priority may only be used by filter implementation,
so reject the attempts to create such filters by client drivers.

Fixes: f9565517ff4f ("net/sfc/base: import filters support")
