Add station uptime parameter in debugfs. This will be helpful to get a
measure of stability of connection and also during stress testing.

I think jiffies can easily overflow. Maybe it would be better to get a
timeval from the monotonic clock.
Thanks, yes thats true and I assumed this will work fine for 49 days
assuming 32 bit(please correct me if my calculations are wrong). will
the overflow will take place in less than this time?.
Yes, but there are people that deploy point to point links that can last
longer than that ;)
I will dig more into it by looking at the time val.
Thanks.
