being used anywhere outside in the tree, I get this warning for unused function. Ideally I should delete it. If I delete it, then I end up deleting all other functions also. But this rtems_3c509_driver_attach() stores references to different handlers & calls them by passing a ifnet structure to if_attach(). I think it's a very important method & I don't think I should delete it.</span></div><div style="color: rgb(0, 0, 0); font-size: 13px; font-family: arial, helvetica, sans-serif; background-color: transparent; font-style: normal;"><span><br></span></div><div style="color: rgb(0, 0, 0); font-size: 13px; font-family: arial, helvetica, sans-serif; background-color: transparent; font-style: normal;"><span>But this function </span><span style="font-size: 10pt;">rtems_3c509_driver_attach() is neither called locally , nor globally.</span></div><div style="color: rgb(0, 0, 0); font-size: 10pt; font-family: arial, helvetica, sans-serif;
