From 24715bb93ab385ab4a2b7d7114150b2f9fe767e9 Mon Sep 17 00:00:00 2001 From: Andrew Rybchenko Date: Tue, 13 Oct 2020 14:45:32 +0100 Subject: [PATCH] net/sfc: support datapath logs which may be compiled out Add datapath log level which limits logs included in build since on datapath it is too expensive to dive into rte_log() function even if it does nothing.
