ath10k: MESH points are associated ,but not pinging each other

[kavitam]

Hi,

I have  used  backport-4.4.2-1. I have downloaded it from the following 
link(16 Feb 2016):

https://www.kernel.org/pub/linux/kernel/projects/backports/stable/v4.4.2/

I thought this is the latest stable version. Is this correct?

Thanks & Regards,
Kavita
