If a DDP broadcast packet is sent out to a non-gateway target, it is also looped back. There is a potential for the loopback device to have a longer hardware header length than the original target route's device, which can result in the skb not being created with enough room for the loopback device's hardware header. This patch fixes the issue by determining that a loopback will be necessary prior to allocating the skb, and if so, ensuring the skb has enough room. This was discovered while testing a new driver that creates a LocalTalk network interface (LTALK_HLEN = 1). It caused an skb_under_panic.
