Subject: [linux-next][selftests/bpf] Kernel ABI header at
 'tools/include/uapi/linux/if_xdp.h'

Hello,


I am observing build warnings. while compiling selftests/bpf on the 
next-20250508 repo.


Warnings:


Warning: Kernel ABI header at 'tools/include/uapi/linux/if_xdp.h' 
differs from latest version at 'include/uapi/linux/if_xdp.h'
