This patch adds padding to the start of frames to make room for headroom for us to eventually start using build_skb. Right now we guarantee at least NET_SKB_PAD + NET_IP_ALIGN, however we allocate more space if more is available. For example on x86 the headroom should be 192 bytes. On systems that have too large of a cache line size to support storing 1.5K padding and shared info we default to using 3K buffers and reserve everything that isn't used for skb_shared_info or the data buffer for headroom.
