Upstream commit [1] caused regression in IPv4 routing which can cause some
routes becoming broadcast even though they should be routed as unicast, e.g.:
# ip route get 1.1.1.1
broadcast 1.1.1.1 via 192.168.122.1 dev enp0s3 src 192.168.122.204 uid 0
cache <local,brd>
It's not entirely clear yet why it happens but this behavior seems to be
triggered for instance when the SSDP integration sends the broadcast packet on
HA startup. While this behavior is not described in the regression report [1],
the commit cherry-picked from Linux master fixes the problems for us as well.
Patches moved to version-specific folder, as this one shouldn't be applied on
Raspberry Pi targets.
