Prefer using the POSIX constant PATH_MAX instead of the legacy BSD

are <sys/param.h> and <limits.h>, respectively.

There is no special reason to use the secure version of getenv, thus let's

After commit 8250bc9f ("ss: Unify inet sockets output") raw sockets
are displayed as udp because dgram_show_line() is used for both and
thus IPPROTO_UDP is used for both so proto_name() returns "udp".
Fix this by checking dg_proto which is set according to the caller of
dgram_show_line().

Add a start of a man-page to the misc section as a reference and
guide on (e)BPF classifier and actions. Given that tc is only tersely
documented, this is provided in the hope that users will have an
easier getting started with tc and (e)BPF. And, that there's now more
incentive for others to also start documenting their classifier and
actions as well. ;)

This patch fixes incorrect -EINVAL errors due to invalid
scope and type during mpls route deletes.

$ip -f mpls route add 100 as 200 via inet 10.1.1.2 dev swp1

$ip -f mpls route show
100 as to 200 via inet 10.1.1.2 dev swp1

$ip -f mpls route del 100 as 200 via inet 10.1.1.2 dev swp1
RTNETLINK answers: Invalid argument

$ip -f mpls route del 100
RTNETLINK answers: Invalid argument

After patch:

$ip -f mpls route show
100 as to 200 via inet 10.1.1.2 dev swp1

$ip -f mpls route del 100 as 200 via inet 10.1.1.2 dev swp1

$ip -f mpls route show

Always set type to RTN_UNICAST for mpls route add/deletes.
Also to keep things consistent with kernel set scope to
RT_SCOPE_UNIVERSE for both mpls and ipv6 routes. Both mpls and ipv6 route
deletes ignore scope.

Kernel commit 04fd61ab36ec ("bpf: allow bpf programs to tail-call other
bpf programs") added support for tail calls, this patch here adds tc
front end parts for the object parser to prepopulate a given eBPF prog
array before the root prog is pushed down for classifier creation. The
prepopulation works with any number of prog arrays in any dependencies,
e.g. prog or normal maps could also be used from progs that are
tail-called themself, etc.
