My original suggestion was to use normal values in 'enum skb_drop_reason', even if there was not necessarily a 'drop' in the common sense. https://lore.kernel.org/all/CANn89iJw8x-LqgsWOeJQQvgVg6DnL5aBRLi10QN2WBdr+X4k=w...@mail.gmail.com/ This would avoid these ugly casts later, even casting an enum to other ones is not very logical. Going through an u32 pivot is quite a hack. If you feel the need to put them in a special group, this is fine by me.
