Merge branch 'ipv4-invalidate-broadcast-neigh-upon-address-addition'
Ido Schimmel says:
====================
ipv4: Invalidate neighbour for broadcast address upon address addition
Patch #1 solves a recently reported issue [1]. See detailed description
in the changelog.
Patch #2 adds a matching test case.
Targeting at net-next since as far as I can tell this use case never
worked.
There are no regressions in fib_tests.sh with this change:
# ./fib_tests.sh
...
Tests passed: 186
Tests failed: 0
