[ Upstream commit 1833d8a26f057128fd63e126b4428203ece84684 ]
According to the Marvell datasheet the 88E6361 has two VTU pages (4k VIDs per page) so the max_vid should be 8191, not 4095.
In the current implementation mv88e6xxx_vtu_walk() gives unexpected results because of this error. I verified that mv88e6xxx_vtu_walk() works correctly on the MV88E6361 with this patch in place.
