Nick Hainke d16758d2d3 xdp-tools: fix musl build issues 
Add patches to fix build failures on musl-based toolchains:

0002-xdpsock-fix-struct-ethhdr-redefinition-on-musl.patch:
xdpsock.c included <net/ethernet.h> and <netinet/ether.h> alongside
<linux/if_ether.h>, triggering a struct ethhdr redefinition on musl.
Replace BSD-style ether_header/ether_addr with struct ethhdr and drop
the conflicting includes.

0003-build-use-gnu2x-to-avoid-stdbool.h-dependency.patch:
Switch CFLAGS and BPF_CFLAGS from -std=gnu11 to -std=gnu2x. In C23,
bool is a native keyword, fixing "stdbool.h: No such file or directory"
errors with a clang lacking its resource directory (e.g. llvm-bpf built
with LLVM_INSTALL_TOOLCHAIN_ONLY=ON on musl targets).

TITLE:=xdp-bench - an XDP benchmarking tool
DEPENDS+=@KERNEL_DEBUG_INFO_BTF @KERNEL_KPROBES
endef
define Package/xdp-bench/description
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.
endef
define Package/xdp-filter
$(call Package/xdp-tools/Default)
TITLE:=xdp-filter - a simple XDP-powered packet filter
endef
define Package/xdp-filter/description
xdp-filter is a packet filtering utility powered by XDP. It is deliberately
simple and so does not have the same matching capabilities as, e.g.,
netfilter. Instead, thanks to XDP, it can achieve very high drop rates:
tens of millions of packets per second on a single CPU core.
endef
define Package/xdp-forward
$(call Package/xdp-tools/Default)
TITLE:=xdp-forward - the XDP forwarding plane
DEPENDS+=@KERNEL_DEBUG_INFO_BTF
endef
define Package/xdp-forward/description
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.
The userspace component of xdp-forward will then configure and
load XDP programs on those interfaces, and forward packets between
them using XDP_REDIRECT, using the kernel routing table or
netfilter flowtable to determine the destination for each packet.
endef
define Package/xdp-loader
$(call Package/xdp-tools/Default)
TITLE:=xdp-loader - an XDP program loader
endef
define Package/xdp-loader/description
xdp-loader is a simple loader for XDP programs with support for attaching
multiple programs to the same interface. To achieve this it exposes the same
load and unload semantics exposed by the libxdp library.
endef
define Package/xdp-monitor
$(call Package/xdp-tools/Default)
TITLE:=xdp-monitor - a simple XDP tracepoint monitoring tool
DEPENDS+=@KERNEL_DEBUG_INFO_BTF @KERNEL_KPROBES
endef
define Package/xdp-monitor/description
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.
endef
define Package/xdp-trafficgen
$(call Package/xdp-tools/Default)
TITLE:=xdp-trafficgen - an XDP-based packet generator
DEPENDS+=@KERNEL_DEBUG_INFO_BTF @KERNEL_KPROBES
endef
define Package/xdp-trafficgen/description
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).
XDP-trafficgen supports generating UDP traffic with fixed or dynamic
destination ports, and also has basic support for generating dummy
TCP traffic on a single flow.
