[PATCH net v2 4/6] net: dsa: microchip: ksz8: ksz8_fdb_dump: avoid extracting ghost entry from empty dynamic MAC table.

From: Oleksij Rempel
Date: Fri Mar 24 2023 - 04:07:10 EST


If the dynamic MAC table is empty, we will still extract one outdated
entry. Fix it by using correct bit offset.

Fixes: 4b20a07e103f ("net: dsa: microchip: ksz8795: add support for ksz88xx chips")
