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

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 ?
After much experimenting, I've managed to get it to work.
Based on the original board.c file copied from the TI starter kit, I
simply changed the slaves count to 2, and set CONFIG_PHY_ADDR to 1 in my
board config file.
Simple.
