This change was investigated previously [1] but not deemed necessary. With
the recent addition [2] of modern BPF loader support, however, tc gained
dependencies on libelf and libbpf, with a larger installation footprint.
Similar to ip-tiny/ip-full, split tc into tc-full and tc-tiny variants,
where the latter excludes the eBPF loader, uses a smaller executable, and
avoids libelf and libbpf package dependencies. Both variants provide the
'tc' virtual package, with tc-tiny as the default.
The previous tc package included a loadable module for iptables actions.
Separate this out into a common package, tc-mod-iptables, which both
variants depend on. Some package sizes on mips_24kc:
Before:
148343 tc_5.11.0-1_mips_24kc.ipk
After:
144833 tc-full_5.11.0-2_mips_24kc.ipk
138430 tc-tiny_5.11.0-2_mips_24kc.ipk (and no libelf or libbpf)
4115 tc-mod-iptables_5.11.0-2_mips_24kc.ipk
Also fix up some Makefile indentation.

The link equalizer sch_teql.ko of package kmod-sched relies on a hotplug
script historically included in iproute2's tc package. In previous
discussion [1], consensus was the hotplug script is best located together
with the module in kmod-sched, but this change was deferred at the time.
Relocate the hotplug script now. This change also simplifies adding a tc
variant for minimal size with reduced functionality.

This patch has been submitted upstream to fix an error reported by a few
users. One instance seen using gcc 10.2.0, binutils 2.35.1 and musl 1.1.24:
bpf_glue.c: In function 'get_libbpf_version':
bpf_glue.c:46:11: error: 'PATH_MAX' undeclared (first use in this function);
did you mean 'AF_MAX'?

The latest iproute2 version brings various improvements and fixes:
https://git.kernel.org/pub/scm/network/iproute2/iproute2.git/log/?qt=range&q=v5.10.0..v5.11.0
In particular, ip and tc now use libbpf as the standard way to load BPF
programs, rather than the old, limited custom loader. This allows more
consistent and featureful BPF program handling e.g. support for global
initialized variables.
Also fix a longstanding problem with iproute2 builds where unneeded DSO
dependencies are added to most utilities, bloating their installation
footprint. From research and testing, explicitly using a "--as-needed"
linker flag avoids the issue. Update accordingly and drop extra package
dependencies from Makefile.
Additional build and packaging updates include:
- install missing development header to iproute2/bpf_elf.h
- propagate OpenWrt verbose flag during build
- update and refresh patches
Compile and run tested: QEMU/malta-mips32be on kernels 5.4 & 5.10.
All iproute2 packages were built and installed to the test image. Some
regression testing using ip-full and tc was successfully performed to
exercise several kmods, tc modules, and simple BPF programs.

Feature detection doesn't recognize ipset v7 use on kernel v5.x systems
and thus disables the tc ematch function em_ipset.

In iproute2, some of object, header, source files are used in
qos-gargoyle.
qos-gargoyle will find these files in build_dir.
But if CONFIG_AUTOREMOVE is enable in SDK, an error "Header not found." will be raised.
So one way is that copying these files to staging_dir.
Allows proper usage of the ss tool. Otherwise, several errors and bad
data gets thrown:
