net: dsa: microchip: correct KSZ8795 static MAC table access
[ Upstream commit 4bdf79d6 ] The KSZ8795 driver code was modified to use on KSZ8863/73, which has different register definitions. Some of the new KSZ8795 register information are wrong compared to previous code. KSZ8795 also behaves differently in that the STATIC_MAC_TABLE_USE_FID and STATIC_MAC_TABLE_FID bits are off by 1 when doing MAC table reading than writing. To compensate that a special code was added to shift the register value by 1 before applying those bits. This is wrong when the code is running on KSZ8863, so this special code is only executed when KSZ8795 is detected.
