Subject: wifi: iwlwifi: mld: Handle rate selection for NAN interface
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=dbbeebece03050cd510073ce89fee83844e06b00;p=thirdparty%2Fkernel%2Flinux.git

wifi: iwlwifi: mld: Handle rate selection for NAN interface

Frames transmitted over a NAN interface might not have channel
information assigned to them. In such cases assign the lowest
OFDM to the frame.
