Revert netlink-packet-core bump to 0.7 in 0.11.z release

[nox]

Bumping netlink-packet-core from 0.5 to 0.7 is a breaking change because netlink-packet-core is part of the public API of netlink-proto. It should thus be bumped as part of a major release of netlink-proto, i.e. netlink-proto 0.12.

Users cannot build rtnetlink 0.12 anymore because it depends on netlink-packet-core 0.5 and netlink-proto 0.11, and items from netlink-packet-core 0.5 cannot be used with netlink-proto 0.11.2 anymore.

Running into the same issues, breaking dependencies for me

Same here

Note the issue can be worked around by pinning netlink-proto to 0.11.1 (or bumping all netlink crates), but it's just a workaround

It should works well with 0.11.3+ now with a cargo update.

Problem is still here, you can't use netlink-packet-core 0.5 with netlink-proto 0.11.2 and above.
