Because of the logic in place, SW_HUGE_PACKET can never be set.
(If the first condition is true, then the 2nd one is also true, but is not
executed)

Change the logic and update each bit individually.

Since ksz8_w_sta_mac_table() is only used within ksz8795.c, make it static
to limit its scope.

Prepare for the next patch by ensuring that ksz8_r_sta_mac_table() does
not use error codes for empty entries. This change will enable better
handling of read/write errors in the upcoming patch.

As ksz8_r_sta_mac_table() is only used within ksz8795.c, there is no need
to export it. Make the function static for better encapsulation.

Add support for add/del_fdb operations and utilize the refactored static
MAC table code. This resolves kernel warnings caused by the lack of fdb
add function support in the current driver.

Move static MAC table operations to separate functions in order to reuse
the code for add/del_fdb. This is needed to address kernel warnings
caused by the lack of fdb add function support in the current driver.
