From 5a49dfe51f2291c19e97ad7fd23cc00c4c1aca26 Mon Sep 17 00:00:00 2001 From: Ido Schimmel Date: Fri, 13 Nov 2020 18:05:51 +0200 Subject: [PATCH] mlxsw: spectrum_router: Move IPv4 FIB info into a union in nexthop group struct Instead of storing the FIB info as 'priv' when the nexthop group represents an IPv4 nexthop group, simply store it as a FIB info with a proper comment. When nexthop objects are supported, this field will become a union with the nexthop object's identifier.
