Oh, that was a legacy code, the idea is it used spare area in dev->data array to
keep permanently 8 bytes for mcast filter request.
But the truth is usbnet_write anyway preallocates the data buffer and copies the data in there.
Therefore its really better to just allocate m_filter on stack to make the code clean.
