Subject: [U-Boot] How do I use AM335x eth1 rather than eth0 ?

We have a dual Ethernet board (based on the BeagelBone) but with both Ethernet ports connected.

I'm wanting to use eth1 (rather than eth0), so in my board.c file, I changed:-

static struct cpsw_slave_data cpsw_slaves[] = {
	{
		.slave_reg_ofs	= 0x208,
		.sliver_reg_ofs	= 0xd80,
		.phy_id		= 0,
	},
	{
		.slave_reg_ofs	= 0x308,
		.sliver_reg_ofs	= 0xdc0,
		.phy_id		= 1,
	},
};

... to ...

static struct cpsw_slave_data cpsw_slaves[] = {
	{
		.slave_reg_ofs	= 0x308,
		.sliver_reg_ofs	= 0xdc0,
		.phy_id		= 1,
	},
	{
		.slave_reg_ofs	= 0x208,
		.sliver_reg_ofs	= 0xd80,
		.phy_id		= 0,
	},
};

... assuming that eth0 would now be ignored (as only 1 slave is configured).

But (eg) dhcp still only responds on eth0 !?!

What else do I have to change ?
