Don't pass protocol numbers/addresses to methods in ingress path
ghananigans opened this issue · comments
Similar to #6537, we might be able to drop protocol numbers/addresses from the ingress path and hold it in the packet buffer.
However, this may require repurposing pkt.{Network, Transport}ProtocolNumber to mean different things in ingress/egress packets.
For outgoing packets, they will be the protocol number for a header that is set by the protocol before being passed to the lower protocol.
For incoming packets, they will be the protocol number for the next-layer protocol where the header may not yet be set. Note that pkt.{Network, Transport}ProtocolNumber is currently only set when parsing succeeds on the ingress path. This would need to be updated so that the next-layer protocol number is set when the previous layer successfully parses.
