Subject: [PATCH v1 03/26] net: dsa: microchip: ksz8: ksz8_fdb_dump: fix not complete fdb extraction
Current ksz8_fdb_dump() is able to extract max 249 entries on
the ksz8863/ksz8873 series of switches. This happened due to wrong
bit mask and offset calculation.
With this patch, we will be able to extract all possible 1024 entries.
