+ * LIPP/LEPP, and then uses "tile_net_open_inner()" to register all
+ * the tiles, provide buffers to LIPP, allow ingress to start, and
+ * turn on hypervisor interrupt handling (and NAPI) on all tiles.
+ *
+ * If registration fails due to the link being down, then "retry_work"

+ *
+ * If "ifconfig DEVICE down" is called, it uses "tile_net_stop()" to

+ * We start out with the ingress interrupt enabled on each CPU. When

+ * the actual packet, plus 62 bytes of empty padding, plus some
+ * padding and the "struct skb_shared_info".
+ *
+ * With 64K pages, a large buffer thus needs 32+92+4+2+1536+62+88

+ *
+ * With 4K pages, a large buffer thus needs 32+92+4+2+1536+62+268
