Thanks, The "internal IRQ number plus 16" part is the info I was lacking. However by 'internal IRQ' do you mean DMA? I just asked the hardware engineer and that's what he thought you may have meant. So in '1d' the first cell is the irq and the second cell is the sense level, how is the '1' calculated from 'internal IRQ number plus 16' . Thanks for you patience, I'm just not getting that part yet. > > > - how do I > > know what to use for my external interupts 1,2 for phy's 0,1 using a > > 88E1121R and for external interupts 3,4 for phy's 2,3 using a 88E1111 > > ? > > I thought it was interrupts 0-3, not 1-4?

Do the 0-3 irq's in the mdio node influence in any way the ethernet nodes irq's - the <1d 2 1e 2 22 2> in this example ? Thanks!
