Subject: [PATCH net-next 0/2] nexthop: Support large scale nexthop flushing

From: Ido Schimmel <idosch@...dia.com>

Patch #1 fixes a day-one bug in the nexthop code and allows "ip nexthop
flush" to work correctly with large number of nexthops that do not fit
in a single-part dump.

Patch #2 adds a test case.

Targeting at net-next since this use case never worked, the flow is
pretty obscure and such a large number of nexthops is unlikely to be
used in any real-world scenario.

Tested with fib_nexthops.sh:

Tests passed: 219
Tests failed:   0

Ido Schimmel (2):
  nexthop: Restart nexthop dump based on last dumped nexthop identifier
  selftests: fib_nexthops: Test large scale nexthop flushing
