4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Nikolay Aleksandrov <nikolay@xxxxxxxxxxxxxxxxxxx>
commit 1288aa7af20cfa25cb00cf0d77f94d1891644c83 upstream.
We need to explicitly zero is_sticky when creating a new fdb, otherwise
we might get a stale value for a new entry.
Fixes: 435f2e7cc0b7 ("net: bridge: add support for sticky fdb entries")
