That's not a good patch - one change is mac80211 and the other
cfg80211.

How are you planning to comply with 802.11 now?

The HT Protection field in a mesh STA may be set to no protection mode
only if
— All STAs detected in the primary or the secondary channel are HT
  STAs, and
— All mesh STA members of this MBSS that are one-hop neighbors of the
  transmitting mesh STA are either:
  — 20/40 MHz HT mesh STAs in a 20/40 MHz MBSS, or
  — 20 MHz HT mesh STAs in a 20 MHz MBSS.
