I'm currently looking at a problem where I might need a network device
to use a "pseudo" device of sorts (or a nexus/leaf relationship not
reflected in the PROM tree) or possibly using a device where the PPA
(network interface number) is not something that can be determined just
by looking at the device tree. (Basically, I've a situation with one
PCI function that has multiple physical ethernet ports, and I need to be
able to AI install over *both* of them.)
Under the old NFS boot/Jumpstart, this required the PROM to tell us more
information, and there was a hand off of the device path to the newly
booted installation kernel.
I *think* under PXE its likely that this is not needed anymore, but I'd
like confirmation.
Will AI work with a device like this without user intervention? How
does it select the interface to use? Does it just try to DHCP on every
one of them and pick the first one that gives an acceptable answer?
Does it just use NWAM to auto select an interface?
I'd really like to understand what requirements a NIC driver must meet,
if any, to work properly with AI.
Thanks.
