This is because the upper 16 bits are used to store errno (for NF_DROP) or the queue number (NF_QUEUE verdict). As there are up to 0xffff different queues available, there is no more room to store additional flags. At the moment there are only 6 different verdicts, i.e. we can reduce NF_VERDICT_MASK to 0xff to allow storing additional flags in the 0xff00 space. NF_VERDICT_BITS would then be reduced to 8, but because the value is exported to userspace, this might cause breakage; e.g.: e.g. 'queuenr = (1 << NF_VERDICT_BITS) | NF_QUEUE' would now break. Thus, remove NF_VERDICT_BITS usage in the kernel and move the old value to the 'userspace compat' section.
