Same technique than some Intel drivers, for arches where PAGE_SIZE = 4096 In most cases, pages are reused because they were consumed before we could loop around the RX ring. This brings back performance, and is even better, a single TCP flow reaches 30Gbit on my hosts. v2: added full memset() in mlx4_en_free_frag(), as Tariq found it was needed if we switch to large MTU, as priv->log_rx_info can dynamically be changed.
