Currently, hash_item() processes the 6-byte Ethernet address and the 2-byte session ID byte-wise to compute a hash. Optimize this by using 16-bit word operations: XOR three 16-bit words from the Ethernet address and the 16-bit session ID, then fold the result. This reduces the total number of loads and XORs. The Ethernet addresses in a skb and struct pppoe_addr are both 2-byte aligned, so the u16 pointer cast is safe.
