Remove upstreamed:
- 010-configure-respect-LDFLAGS.patch
- 020-libxdp-Use-__noinline__-reserved-attribute-for-XDP-d.patch
- 024-lib-allow-overwriting-W-flags-via-BPF_CFLAGS.patch
- 025-Add-BPF_LDFLAGS-to-allow-overwriting-llc-s-march-arg.patch
Remove unnecessary patch:
- 022-xdp-dump-add-missing-perf_event-include-for-bpf-and-.patch
(The included headers were incorrect. Some musl toolchain headers
appeared in the BPF bytecode generation path, which should not
happen. This issue is resolved by overriding CFLAGS and LDFLAGS.)
Remove `PKG_FLAGS:=nonshared`. With this flag enabled, the package is
compiled separately for every target. Removing it limits compilation
to each CPU architecture instead, significantly reducing unnecessary
build overhead.
Add new tools:
- xdp-bench:
XDP-bench is a benchmarking utility for exercising the different operation modes
of XDP. It is intended to be a simple program demonstrating the various operating
modes; these include dropping packets, hairpin forwarding (using the XDP_TX return
code), and redirection using the various in-kernel packet redirection facilities.
- xdp-forward:
xdp-forward is an XDP forwarding plane, which will accelerate
packet forwarding using XDP. To use it, simply load it on
the set of interfaces to accelerate forwarding between.
- xdp-monitor:
XDP-monitor is a tool that monitors various XDP related statistics and
events using BPF tracepoints infrastructure, trying to be as low overhead
as possible.
- xdp-trafficgen:
XDP-trafficgen is a packet generator utilising the XDP kernel subsystem
to generate packets transmit them through a network interface.
Packets are dynamically generated and transmitted in the kernel,
allowing for high performance (millions of packets per second per core).

-Subject: [PATCH] libxdp: Use __noinline__ reserved attribute for XDP
- dispatcher
-
-The use of noinline is wrong as noline is not a reserved attribute and
-with gcc12 this became an error. Use the reserved __noinline__ attribute
-to fix compilation error.

-Subject: [PATCH] lib: allow overwriting -W* flags via BPF_CFLAGS
-
-The bpf header file situation is a mess, and the default warning
-compiler flags may not be suitable everywhere, especially with -Werror
-in the mix.
-
-Move BPF_CFLAGS further down, so these can be overwritten by builders.
