I have four fxp's in a Dell Dimension P100t (well, P75t, but I had this
extra processor...) and had to go through the manual process of adding
each card in separately, recording the Ethernet address, and checking
FreeBSD's detection/numbering of the devices by the Ethernet addresses.
It turned out that there wasn't a simple ordering of the devices. If the
top of the screen corresponds to the rear of the computer, looking from
above, I ended up with:
e ffff
p xxxx
0 pppp
3012
I suppose that maybe fxp3 is out of order because it's a shared slot or
something. I don't know much about how that works. But it seems
reasonable to assume that this could vary by PCI chipset, and so it's not
safe to assume any particular ordering; one could really mess up one's
static routing if one assumed wrongly.
But you already know from your existing setup what the Ethernet addr of
your existing fxp is, so when you change de to fxp, you will know whether
you need to adjust your rc.conf. It's a lot easier with one addition!
