Subject: [PATCH net-next 0/2] nexthop: sysctl to skip route notifications on nexthop changes

From: Roopa Prabhu <roopa@...ulusnetworks.com>

Route notifications on nexthop changes exists for backward
compatibility. In systems which have moved to the new
nexthop API, these route update notifications cancel
the performance benefits provided by the new nexthop API.
This patch adds a sysctl to disable these route notifications

We have discussed this before. Maybe its time ? 

Roopa Prabhu (2):
  ipv4: add sysctl to skip route notify on nexthop changes
  ipv6: add sysctl to skip route notify on nexthop changes
