Remove IP version and next header checks for raw sockets

[KingCol13]

RawSocket will currently only send and receive packets which match the given ip_version and ip_protocol. I think the current behaviour tries to match linux sockets. It could be useful to accept all packets, independent of IpVersion and IpProtocol via the same socket however.

Currently if I want to receive Ipv4 and Ipv6 packets for TCP, UDP and ICMP the only way I can see to do this is to create 6 different sockets with 6x the number of buffers (please let me know if I'm missing something).

Perhaps the ip_version and ip_protocol fields could be made Options, or another ExtraRaw socket created if we don't want to change existing behaviour.

this sounds reasonable, yes. A PR would be welcome.
