    net: dsa: microchip: ksz8: fix ksz8_fdb_dump()
    
    [ Upstream commit 88e943e83827a349f70c3464b3eba7260be7461d ]
    
    Before this patch, the ksz8_fdb_dump() function had several issues, such
    as uninitialized variables and incorrect usage of source port as a bit
    mask. These problems caused inaccurate reporting of vid information and
    port assignment in the bridge fdb.
