However, there are some problems with migrating to "vmlinux.h" because there is no definition for utility functions such as endianness conversion (ntohs/htons). Fortunately, the xdp_sample program already has a function that can be replaced to solve this problem. Therefore, this commit attempts to separate these functions into a file called net_shared.h to make them universally available. Additionally, this file includes network-related macros that are not defined in "vmlinux.h". (inspired by 'selftests' bpf_tracing_net.h) Signed-off-by: Daniel T.

Since vmlinux.h conflicts with tools/include for READ_ONCE/WRITE_ONCE and ARRAY_SIZE, they are copied in to xdp_sample.bpf.h along with other helpers that will be required.
