I'm not sure what you mean. Do you have source code for QEMU emulation
of the network card?
If you have some other source code like a driver for the card, or
emulation for the card but not for QEMU, then a lot more work would be
necessary to emulate the card in QEMU.

QEMU uses mechanisms to send raw packets from userspace, like the
tun/tap driver that many OSes have. Therefore the physical NIC doesn't
matter, it's abstracted by the tun/tap interface that the host kernel
provides.
