But the else-if block which I removed in v2 of this patch had nothing
in the block.
It was not assigning any value to "phtpriv->ampdu_enable". ( basically
it was empty and useless)
Now as per your suggestion if I do the change then the value of
"phtpriv->ampdu_enable" will be changed to true when we have
"pregistrypriv->ampdu_enable == 2" condition. But in real it should be
the same as it was by default coming from the start of the function.
( This is because the else-if block was empty and doing nothing )
Please let me know if I was able to make you understand my point of
view here. Also, please correct me if I am wrong.
Thanks
