RE: [Xen-devel] RE: changeset 16405: Add e100 NIC support.
I don't read e1000 spec. it's an igbx card so I think it works with less port
IO and MMIO access. This will benefit current QEMU
device model.
Seems Longhorn released with no e100 driver, but e1000 driver
should be included. Somebody implements an e1000 emulator is really appreciated.
Good good study,day day up ! ^_^
