That's not a good patch - one change is mac80211 and the other
cfg80211.
- .ht_opmode = IEEE80211_HT_OP_MODE_PROTECTION_NONHT_MIXED,
+ .ht_opmode = IEEE80211_HT_OP_MODE_PROTECTION_NONE,
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.

Good point, this changed should be removed.
The reason for this change was that we've noticed a difference between mesh beacon (built by the mac80211) and mesh actions (built by the supplicant) in the HT information IE.
In beacons the HT operational mode is Mixed Mode (0x11) while in actions it is None (0x00).
After a second look, it seems that it's the Supplicant that doesn't set the default value correctly.
We'll send an updated patch for it.
Thanks,
Yaniv
