packet(7) specifies many socket options, fanout, rx_ring, etc. We should look into adding them.

Which socket options should go first?

probably PACKET_ADD_MEMBERSHIP/PACKET_DROP_MEMBERSHIP

  • PACKET_AUXDATA is for recvmsg() which we don't currently support
  • PACKET_FANOUT seems a bit complicated
  • PACKET_STATISTICS doesn't look very useful
  • PACKET_QDISC_BYPASS only makes sense after write support is done

everything else depends on RXRING/TXRING, which I haven't yet figured out how to use
