Feature or enhancement

Proposal:

When working through the constants in socket for typeshed, I found that these appear to be obsolete:

NETLINK_ARPD: int  # linux 2.0 to 2.6.12 (EOL August 2005)
NETLINK_ROUTE6: int  # linux 2.2 to 2.6.12 (EOL August 2005)
NETLINK_SKIP: int  # linux 2.0 to 2.6.12 (EOL August 2005)
NETLINK_TAPBASE: int  # linux 2.2 to 2.6.12 (EOL August 2005)
NETLINK_TCPDIAG: int  # linux 2.6.0 to 2.6.13 (EOL December 2005)
NETLINK_W1: int  # linux 2.6.13 to 2.6.17 (EOL October 2006)

The netlink constants are defined in include/linux/netlink.h on linux 2.0 to 3.6. Starting in 3.7 they moved to include/uapi/linux/netlink.h. I've annotated these with the versions of linux where I was able to find them, and confirmed that they're not present in FreeBSD's Netlink implementation either.

I suspect these can be safely removed, but I'm not terribly familiar with Netlink myself.

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere
