[Qemu-devel] [PULL 21/21] hw/net/ne2000: Extract the PCI device from the chipset common code

[Paolo Bonzini]

From: Philippe Mathieu-Daudé <address@hidden>

The ne2000.c file contains functions common the the ISA and PCI
devices. To allow to build with one or another, extract the PCI
specific part into a new file.

This fix an issue where the NE2000_ISA Kconfig had to pull the
full PCI core objects.
