MACIOC_SETALLMCA(7mdi)
MACIOC_SETALLMCA --
MDI deliver multicast frames ioctl
Description
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.
Parameters
None.
Data returned
The MDI driver should fail this ioctl
if the adapter is not capable of receiving
all multicast addresses.

to support this ioctl.
