Title:
  lan9118 bug peeked received message size not equal to actual received
  message size

Status in QEMU:
  Fix Committed

Bug description:
  peeked message size is not equal to read message size

  Bug in the code at line:
  https://github.com/qemu/qemu/blob/master/hw/net/lan9118.c#L1209

  s->tx_status_fifo_head should be s->rx_status_fifo_head

  Could also be a security bug, as the user could allocate a buffer of
  size peeked data smaller than the actual packet received, which could
  cause a buffer overflow.

  Thanks,

  Alfred
