This function is to be used from dump callbacks to decide if the output
currect output should be filtered off or not. Filtering is based on
previously parsed and stored command line options.

It is handy to have parsed cmdline data stored so they can be used for
dumps filtering. So split original dl_argv_parse_put into parse and put
parts.

Kernel sets info->tcpi_min_rtt to ~0U when no RTT sample was ever
taken for the session, thus min_rtt is unknown.

Passing a filter expression and selecting an address family using the
'-f' flag would overwrite the state filter by accident. Therefore
calling e.g. 'ss -nl -f inet '(sport = :22)' would not only print
listening sockets (as requested by '-l' flag) but connected ones, as
well.

Fix this by reusing the formerly ineffective call to filter_states_set()
to restore the state filter as it was before the call to
filter_af_set().

It doesn't make sense to use external control plane and fill internal FDB at
the same time. It's even an illegal combination for VXLAN-GPE.

Just switch off learning when 'external' is specified.

Follow-up to kernel commit 6c9059817432 ("bpf: pre-allocate hash map
elements"). Add flags support, so that we can pass in BPF_F_NO_PREALLOC
flag for disallowing preallocation. Update examples accordingly and also
remove the BPF_* map helper macros from them as they were not very useful.

Make it easier to spot issues when loading the object file fails. This
includes reporting in what pinned object specs differ, better indication
when we've reached instruction limits. Don't retry to load a non relo
program once we failed with bpf(2), and report out of bounds tail call key.

Also, add truncation of huge log outputs by default. Sometimes errors are
quite easy to spot by only looking at the tail of the verifier log, but
logs can get huge in size e.g. up to few MB (due to verifier checking all
possible program paths). Thus, by default limit output to the last 4096
bytes and indicate that it's truncated. For the full log, the verbose option
can be used.

Add the optional keyword "vid" to bridge vlan show so the user can
request filtering by a specific vlan id. Currently the filtering is
implemented only in user-space. The argument name has been chosen to
match the add/del one - "vid". This filtering can be used also with the
"-compressvlans" option to see in which range is a vlan (if in any).
Also this will be used to show only specific per-vlan statistics later
when support is added to the kernel for it.

Examples:
$ bridge vlan show vid 450
port	vlan ids
eth2	 450

$ bridge -c vlan show vid 450
port	vlan ids
eth2	 400-500

$ bridge vlan show vid 1
port	vlan ids
eth1	 1 PVID Egress Untagged
eth2	 1 PVID
br0	 1 PVID Egress Untagged
