We are the owner of the current buffer that is being processed, so the refcount will be at least 1. If the current owner of the buffer at the diametrically opposed index in the RX ring (i.o.w, the other half of this page) has not yet called kfree(), this page's refcount could even be 2. enetc_page_reusable(
