Subject: [PATCH] networkd: Consider linkLocalAddressing state while
configuring ndisc. (#7012)
If linkLocalAddressing is disabled in for the interface still then
we look for ndisc configured or not in link_check_ready.
Link local is used automatic address configuration and neighbor discovery protocol.
If link local is disabled we should not configure ndisc.
Fixes #2713, #6441, #5841.
(cherry picked from commit 702c979fefc6d3e69c5982b8469ec8a47792d62f)
