The if statement:
if (port >= DSAF_GE_NUM)
return;
limits the value of port less than DSAF_GE_NUM (i.e., 8).
However, if the value of port is 6 or 7, an array overflow could occur:
port_rst_off = dsaf_dev->mac_cb[port]->port_rst_off;
because the length of dsaf_dev->mac_cb is DSAF_MAX_PORT_NUM (i.e., 6).
To fix this possible array overflow, we first check port and if it is
greater than or equal to DSAF_MAX_PORT_NUM, the function returns.
