heads up bestie: the NAME line is serious business βadd_u32_u32_fxadds twou32fixed point values and discards overflow. that's the whole personality. overflow who? never heard of her π
and that's the page, bestie π this gem lives in ./drivers/net/ethernet/intel/ice, dated October 2026 β go say hi to the whole ice PTP family, they're all so iconique πβπ
