[Qemu-devel] is it just me or is ne2k broken in qemu?

I performed several tests of various emulated NICs booting with iPXE, and discovered that ne2k_pci (*) emulated device does not quite work, for quite some time already, at least with linux guests. The NIC works for a while, but after a few packets, or a few 1000s of packets, it stalls. In tcpdump
