    net: dsa: microchip: ksz8: fix ksz8_fdb_dump() to extract all 1024 entries
    
    [ Upstream commit 5d90492dd4ff50ad65c582c76c345d0b90001728 ]
    
    Current ksz8_fdb_dump() is able to extract only max 249 entries on
    the ksz8863/ksz8873 series of switches. This happened due to wrong
    bit mask and offset calculation.
    
    This commit corrects the issue and allows for the complete extraction of
    all 1024 entries.
