Re: [PATCH net-next 0/3] ip: add RECVFRAGSIZE cmsg

On IP datagrams and raw sockets, when packets arrive fragmented,
expose the largest received fragment size through a new cmsg.

Protocols implemented on top of these sockets may use this, for
instance, to inform peers to lower MSS on platforms that silently
allow send calls to exceed PMTU and cause fragmentation.

Looks good, series applied, thanks Willem.
