From d0a59722135ec77e637097ef99edb6865bc38929 Mon Sep 17 00:00:00 2001 From: Florin Coras Date: Sun, 15 Oct 2017 17:41:21 +0000 Subject: Revert "Enforce FIB table creation before use" This reverts commit f9342023c19887da656133e2688a90d70383b0c5. Reverting to unblock master. No idea why jjb +1ed this patch! On closer inspection it looks like it -1ed it and subsequently changed opinion. CSIT tests should be fixed before re-merging.
