[Qemu-devel] [PATCH v5 0/3] make mac programming for virtio net more robust

[Amos Kong]

Currenly mac is programmed byte by byte. This means that we
have an intermediate step where mac is wrong. 

Third patch introduced a new vq control command to set mac
address, it's atomic.

V2: check return of sending command, delay eth_mac_addr()
V3: restore software address when fail to set hardware address
V4: split eth_mac_addr, fix error handle
V5: rebase patches to net-next tree

Amos Kong (2):
  move virtnet_send_command() above virtnet_set_mac_address()
  virtio-net: introduce a new control to set macaddr

Stefan Hajnoczi (1):
  net: split eth_mac_addr for better error handling
