Broadly, this change: * Enables sockets to be created via `socket(AF_INET, SOCK_RAW, IPPROTO_ICMP)`. * Passes the network-layer (IP) header up the stack to the transport endpoint, which can pass it up to the socket layer. This allows a raw socket to return the entire IP packet to users. * Adds functions to stack.TransportProtocol, stack.Stack, stack.transportDemuxer that enable incoming packets to be delivered to raw endpoints. New raw sockets of other protocols (not ICMP) just need to register with the stack. * Enables ping.endpoint to return IP headers when created via SOCK_RAW.

IP_MULTICAST_LOOP controls whether or not multicast packets sent on the default route are looped back. In order to implement this switch, support for sending and looping back multicast packets on the default route had to be implemented. For now we only support IPv4 multicast.

Having raw socket code together will make it easier to add support for other raw network protocols. Currently, only ICMP uses the raw endpoint. However, adding support for other protocols such as UDP shouldn't be much more difficult than adding a few switch cases.

The code here appears to be vestigial, so removing it and allowing a nil waker to be passed seems appropriate.
