Subject: mlxsw: spectrum: router: Squash the default route table to main
Patch-mainline: v4.15-rc1
Git-commit: 7e50d435759accec4e17764a8d5a1ef63b79ffd6
References: bsc#1112374

Currently, the mlxsw Spectrum driver offloads only either the RT_TABLE_MAIN
FIB table or the VRF tables, so the RT_TABLE_LOCAL table is squashed to the
RT_TABLE_MAIN table to allow local routes to be offloaded too.

By default, multicast MFC routes which are not assigned to any user
requested table are put in the RT_TABLE_DEFAULT table.

Due to the fact that offloading multicast MFC routes support in Spectrum
router logic is going to be introduced soon, squash the default table to
MAIN too.
