virNetDevBridgeSetSTPDelay accepts delay in milliseconds,
but BSD implementation was expecting seconds. Therefore,
it was working correctly only with delay == 0.

Does FreeBSD really not allow setting a delay less than 4 seconds ?
That would make PXE boot fairly unreliable, because QEMU will start
and iPXE will run significantly before that 4 second network delay
has expired causing the PXE packets to be lost.
