[PATCH 4.18 020/168] nl80211: Pass center frequency in kHz instead of MHz
From: Greg Kroah-Hartman
Date:  Mon Oct 08 2018 - 14:46:18 EST
4.18-stable review patch.  If anyone has any objections, please let me know.
------------------
From: Haim Dreyfuss <haim.dreyfuss@xxxxxxxxx>
[ Upstream commit b88d26d97c41680f7327e5fb8061ad0037877f40 ]
freq_reg_info expects to get the frequency in kHz. Instead we
accidently pass it in MHz.  Thus, currently the function always
return ERR rule. Fix that.
Fixes: 50f32718e125 ("nl80211: Add wmm rule attribute to NL80211_CMD_GET_WIPHY dump command")
