Contrary to the comment and expected output, nft does _not_ eliminate
the redundant `ip protocol` expression from the second test. Dependency
elimination requires a higher level expression. `ip saddr` cannot lead
to the elimination of `ip protocol` since they are both L3 expressions.
`tcp dport` cannot because although `ip saddr` and `ip protocol` both
imply that the L3 protocol is `ip`, only protocol matches are stored as
dependencies, so the redundancy is not apparent, and in fact,
`payload_may_dependency_kill` explicitly checks for the combination of
inet, bridge or netdev family, L4 expression and L3 ipv4 or ipv6
dependency and returns false.
Correct the expected output and comment.

Add userspace support for the netdev egress hook which is queued up for
v5.16-rc1, complete with documentation and tests. Usage is identical to
the ingress hook.

All of these are actual errors, i.e. meaning of rule is changed.

This test fails with
'ip protocol tcp tcp dport 22' mismatches 'tcp dport 22'
ip protocol tcp tcp dport 22 is *ONLY* same as 'tcp dport 22' in the
ip family.
For netdev/inet/bridge, the dependency is required, as it restricts
matching to ipv4.
