ifr_flags can contain one or more of the symbolic constants below (defined in
pna.h), in the following syntax:
IFF_BROADCAST | IFF_RAWMEM
Symbolic Constant Description
IFF_BROADCAST NI can broadcast.
IFF_EXTLOOPBACK NI uses external loopback.
IFF_INITDOWN Initialize an interface in the DOWN state. By default interfaces
are installed in the UP state. This flag may only be
specified when initially adding an interface. Note that this
is not an attribute of the NI.
IFF_MULTICAST NI supports multicast.
IFF_NOARP NI does not have ARP.
IFF_POINTTOPOINT NI is point-to-point driver.
IFF_POLL pNA+ polls NI at regular intervals.
IFF_RAWMEM NI passes packets as mblks.
IFF_UNNUMBERED NI is an unnumbered link.
IFF_UP NI is UP.
Memory-Related Operations
SIOCGMBSTAT Gets the statistics for mblks (memory blocks) configured
in the system. A pointer to the mbstat structure is
passed via the arg parameter of the ioctl() call. mbstat
is defined as follows:
