Motivation:

Recent additions added support for UDP_SEGMENT and UDP_GRO on Linux. These are both configured via channel options. Enabing UDP_SEGMENT at the channel level means all datagrams sent will use the same segment size.

We can offer finer-grained control by allowing users to set the segment size at the datagram level by setting the option in the CMSG headers.

We can also recover the segment size on the receive side by reading the header value, this is possible for both methods of setting the segment size.

Modifications:

  • Add segmentSize to AddressedEnvelope.Metadata which sets the segment size on outbound messages and indicates the segment size the sender used on the receive side (assuming GRO is enabled).
  • Add tests

Results:

  • Finer grained control over UDP segmentation.
  • Users can recover the segment size used by the remote peer.

These are both configured via channel options. Enabing UDP_SEGMENT at
the channel level means all datagrams sent will use the same segment
size.

We can offer finer-grained control by allowing users to set the segment
size at the datagram level by setting the option in the CMSG headers.

We can also recover the segment size on the receive side by reading the
header value, this is possible for both methods of setting the segment
size.

Modifications:

- Add `segmentSize` to `AddressedEnvelope.Metadata` which sets the
  segment size on outbound messages and indicates the segment size the
  sender used on the receive side (assuming GRO is enabled).
- Add tests

Results:

- Finer grained control over UDP segmentation.
- Users can recover the segment size used by the remote peer.
