Subject[PATCH 4.18 019/168] nl80211: Fix nla_put_u8 to u16 for NL80211_WMMR_TXOP
Date
4.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Haim Dreyfuss <haim.dreyfuss@intel.com>

[ Upstream commit d3c89bbc7491d5e288ca2993e999d24ba9ff52ad ]

TXOP (also known as Channel Occupancy Time) is u16 and should be
added using nla_put_u16 instead of u8, fix that.

Fixes: 50f32718e125 ("nl80211: Add wmm rule attribute to NL80211_CMD_GET_WIPHY dump command")
