Add ieee80211_get_operstate() function to get the operstate of the netdevice. This is needed for drivers that need to know when the interface is IF_OPER_UP (e.g. wl12xx), and block notifiers can't be used (e.g. because the interface is already IF_OPER_UP, like after resuming from suspend) Signed-off-by: Eliad Peller <redacted> --- include/net/mac80211.h | 10 ++++++++++ net/mac80211/mlme.c | 7 +++++++ 2 files changed, 17 insertions(+), 0 deletions(-)
