Re: [RFC net-next v2 00/18] net: introduce ipxlat stateless IPv4/IPv6 translation

[Xavier HSINYUAN]

Hi Ralf,

Thanks for your v2 series!

Here is a question about netfilter hooks in ipxlat-lwt. In RFC v1,
netdev-based ipxlat allows POST_ROUTING rules to be applied for
original-family before translation. Currently LWT path translates first
and does not check nf_hooks_lwtunnel to optionally run original-family
POST_ROUTING before translation.

Is this difference intentional since it keeps LWT path simple and leave
such cases to netdev path, or would an optional pre-translation pass in
LWT path also be worth considering?

Best regards,
Xavier
