Hi Andrew,

here a short dump of the first chip registers:
> Chip ID0 00
> Chip ID1_2 9893 Chip ID 9893
> Chip ID3 60 Revision ID 6 Reset
> normal
> Chip ID4 1C SKU ID 1C
In ksz9477_switch_detect(), the 32 bit value is built from only
the 2 middle bytes: 0x00989300. The number of port (3) is also
assigned within this function:
> if ((id_lo & 0xf) == 3) {
> /* Chip is from KSZ9893 design. */
> dev->features |= IS_9893;
> /* Chip does not support gigabit. */
> if (data8 & SW_QW_ABLE)
> dev->features &= ~GBIT_SUPPORT;
> dev->mib_port_cnt = 3;
> dev->phy_port_cnt = 2;
> } ...
The chip id 0x00989300 does already exist in ksz9477_switch_chips:
> {

But my chip is really a KSZ9563.
