Subject: [PATCH 12/26] net: dsa: hellcreek: Fix insertion of static FDB
entries
Git-commit: 4db4c3ea56978086ca367a355e440de17d534827
Patch-mainline: v5.17-rc1
References: git-fixes
The insertion of static FDB entries ignores the pass_blocked bit. That bit is
evaluated with regards to STP. Add the missing functionality.
Fixes: e4b27ebc780f ("net: dsa: Add DSA driver for Hirschmann Hellcreek switches")
