Mesh: Accept auth attempts from PLINK_BLOCKED nodes?

We are using TI wl18xx and Mesh with wpa_supplicant 2.10. This module is 
limited to 10 nodes, so it is very common to see that all slots (iw dev 
wlan0_mesh station dump) ends up in the "mesh plink: BLOCKED" state, which 
prevents formation of the mesh. Blocking happens due to SAE auth failures, 
either due to "bad" nodes that should not use this mesh (expected), and 
sometimes even for nodes which should use this mesh and have correct SAE 
credentials (unknown why).

I found the kernel patch on 
which clarifies the NL80211_PLINK_BLOCKED comment and Felix Fietkau 
mentioned a hostapd follow up patch, but I cannot find any such patch? 

The plink blocking does not seem very useful to me; what drawbacks are 
there to setting a very short duration?
