Subject: hw/net/xen_nic.c: Set 'netdev->mac' to NULL after free it
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=a39d97c7becca5fd679d70d17ae5b1d62b9b5da6;p=qemu.git

hw/net/xen_nic.c: Set 'netdev->mac' to NULL after free it

Since net_init() checks whether 'netdev->mac' is NULL, before alloc it;
net_release() also need set 'netdev->mac' to NULL after free it.
