[Qemu-devel] [PATCHv2 0/3] e1000: multi-buffer packet support

[Michael S. Tsirkin]

e1000 supports multi-buffer packets larger than rxbuf_size.

This fixes the following (on linux):
- in guest: ifconfig eth1 mtu 16110
- in host: ifconfig tap0 mtu 16110
           ping -s 16082 <guest-ip>

Red Hat bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=602205

Changes from v1:
        fix buffer overflow reported by Kevin
        added a patch to fix EOP spec violation reported by Juan
        added a patch to fix spec violation noted by myself


Michael S. Tsirkin (3):
  e1000: multi-buffer packet support
  e1000: clear EOP for multi-buffer descriptors
  e1000: verify we have buffers, upfront
