## Overview

In the Linux kernel, the following vulnerability has been resolved:

net: atlantic: fix aq_vec index out of range error

The final update statement of the for loop exceeds the array range, the
dereference of self->aq_vec[i] is not checked and then leads to the
index out of range error.
Also fixed this kind of coding style in other for loop.

v2. fixed "warning: variable 'aq_vec' set but not used"

v3. simplified a for loop
