MACIOC_GETMCA(7mdi)
MACIOC_GETMCA --
MDI return active multicast addresses ioctl
Description (Not in UnixWare version)
This ioctl requests that the MDI driver
return current set of active multicast addresses.
Parameters
The
ioctl(S)
data contains space into which the MDI driver
should copy its multicast address table. The MAC user
will usually issue a
MACIOC_GETMCSIZ(MDI)
ioctl before this to determine the size of the buffer to send
down.
Data returned
The MDI driver should fill the ioctl
data area with its multicast address table. If the ioctl data
area is smaller than is needed, the MDI driver
should copy as many entries as possible from its table. If the
ioctl data area is larger than is needed, the MDI
driver should copy its entire table, and adjust the
b_wptr
and ioc_count
fields to match the
size of the data written into the ioctl data.
