Hi,
I am trying to get at the current monitor flags setting of a wireless
monitor mode virtual interface. I have tried to do this by hacking
the
iw source. However I never see a NL80211_ATTR_MNTR_FLAGS attribute
returned in response to the
TOPLEVEL(info, NULL, NL80211_CMD_GET_INTERFACE, 0, CIB_NETDEV,
handle_interface_info,
"Show information for this interface.");
command in iw's interface.c code.
Questions.
1. Am I wasting my time? (e.g. the rt2800usb driver never returns
this
info, or there is another easy way of viewing this info, etc)
Looks like it's never set in the corresponding kernel code.

Thanks Johannes, that was my conclusion, but I was not sure if that was
true in all cases. I tried another chipset and got the same results. I
am trying to debug a problem with an adapter only seeing broadcast and
multicast packets in monitor mode, and the significance of the setting
of the otherbss flag in this case. It would be really helpful if iw
could return the complete state of an interface, but it looks like that
would require a kernel patch. This seems like a can of worms to me.
