Subject: hw/virtio: fix double use of a virtio flag
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=631a4387554d53a0d19dd7973851ed760a5bff97;p=qmiga%2Fqemu.git

hw/virtio: fix double use of a virtio flag

Commits 1811e64c and a6df8adf use the same virtio feature bit 4
for different features.

Fix it by using different bits.
