Hello,
There seems to be a bug in qemu in the e1000 emulation, which triggers
an issue with the Linux driver.
What happens in Linux is the following:
- e1000_open
- e1000_configure
- e1000_setup_rctl
- enables E1000_RCTL_EN
- e1000_configure_rx
- sets RDT/RDH to 0
- al

Well, it's not with an actual physical device, but with the kvm
emulat
At high traffic rate, the rx ring may get completely filled before we
manage to consume it. After it is filled, the kernel and device indexes
are not synchronized any more, so we have to reset them, otherwise the
kernel will be stuck waiting for the wrong slot to be filled.
