[Qemu-devel] [PATCH for-1.4] e1000: unbreak the guest network migration to 1.3

2013-02-14 Thread Michael S. Tsirkin
QEMU 1.3 does not emulate the link auto negotiation, so if migrate to a 1.3 machine during link auto negotiation, the guest link will be set to down. Fix this by just disabling auto negotiation for 1.3. Signed-off-by: Michael S. Tsirkin --- hw/e1000.c | 25 + hw/pc_piix
