MDI deliver multicast frames ioctl
This ioctl requests that the MDI driver
begin delivering frames sent
to all multicast MAC addresses
in addition to the adapter's MAC address,
the broadcast address, and existing multicast addresses.
The driver will continue to receive frames
on all multicast MAC addresses
until either a MACIOC_DELALLMCA ioctl request
is received or the MDI device is closed.
The MDI driver should fail this ioctl
if the adapter is not capable of receiving
all multicast addresses.
Do not set promiscuous mode and filter out unicast addresses
to support this ioctl.
Acknowledgement should be one of the following:
ioc_count to zero.
ioc_count to zero,
ioc_rval to -1,
ioc_error to one of the following:
Device does not use MAC addresses
