Subject: [PATCH net-next v2 03/16] ipv6: Extend notifier info for multipath routes
Date: Tue, 18 Jun 2019 18:12:45 +0300
Message-ID: <20190618151258.23023-4-idosch@idosch.org> (raw)
In-Reply-To: <20190618151258.23023-1-idosch@idosch.org>

From: Ido Schimmel <idosch@mellanox.com>

Extend the IPv6 FIB notifier info with number of sibling routes being
notified.

This will later allow listeners to process one notification for a
multipath routes instead of N, where N is the number of nexthops.
