[LEDE-DEV] ath10k ct ack timeout/coverage class

[Nick Dennis]

Thanks. i did see something in mail-archive (don't know what source)

https://www.mail-archive.com/search?l=ath10k@lists.infradead.org&q=subject:%22request%5C%3A+ACK+timing+setting+required%22&o=newest&f=1

Does the debugfs setting get overwritten by the ini settings during 
resets and have to be re-done ?

In the past, I just set the ack timeout register without adjusting any 
others and it worked, so I'll try that first.
