Subject: [Patch net v3 0/2] ipv4: relax source validation check for loopback packets

This patchset fixes a corner case when loopback packets get dropped
by rp_filter when we route them from veth to lo. Patch 1 is the fix
and patch 2 provides a simplified test case for this scenario.

Cong Wang (2):
  fib: relax source validation check for loopback packets
  selftests: add a test case for rp_filter

---
v3: use dummy1 instead of dummy0 in the test case
v2: remove a redundant if check and add a test case
