Subject: wifi: iwlwifi: mvm: Remove NAN support
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4459dd6d85b9fbcdbc3803603fba9d78c1cec2c4;p=thirdparty%2Flinux.git

wifi: iwlwifi: mvm: Remove NAN support

NAN is not officially supported on any of the MVM devices so there
is no need to maintain it.
