Marek Vasut 8262e6f9b1 net: ks8851-ml: Fix IO operations, again ... This patch reverts 5829210483 ("net: ks8851-ml: Fix 16-bit IO operation") and edacb098ea ("net: ks8851-ml: Fix 16-bit data access"), because it turns out these were only necessary due to buggy hardware. This patch adds a check for such a buggy hardware to prevent any such mistakes again. While working further on the KS8851 driver, it came to light that the KS8851-16MLL is capable of switching bus endianness by a hardware strap, EESK pin. If this strap is incorrect, the IO accesses require such endian swapping as is being reverted by this patch. Such swapping also impacts the performance significantly. Hence, in addition to removing it, detect that the hardware is broken, report to user, and fail to bind with such hardware.
