Subject: nl80211: remove TCP WoWLAN information
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=162589f7b162b916ac377753c086e3ba76a9f33d;p=linux-beck.git

nl80211: remove TCP WoWLAN information

Just like the radar information, the TCP WoWLAN capability
data can increase the wiphy information and make it too
big. Remove the TCP WoWLAN information; no driver supports
it and new userspace tools will be required as well.
