Motivation:
While adding support for GRO (b05fdf3ff8889c09dbea12d3844116b5489844c6) we broke support for IP_RECVORIGDSTADDR when using the native transport. Beside this we also didnt correctly handle IP_RECVORIGDSTADDR when recvmmsg was used.
Modifications:
- Fix support for IP_RECVORIGDSTADDR when using the native epoll transport for normal reads (recvmsg) but also for scattering reads (recvmmsg)
- Remove code from unix code-base as the support is linux specific and we not need the code there anymore
Result:
Fixes https://github.com/netty/netty/issues/11141
