u32 module works differently from x86

Description

Sirs, I have a ipt rule as
{
-p udp -m udp -sport 53 -m u32 -u32 "0x1e&ffff=0x8180 && 0x22&0xffffffff=0x10000" -j DROP
}

it doesn't work as expected. It still fails after I split the number into d-word / 0xffff with "&&" operator. Is there some limitation on data type or clauses ?

well "0x0&0xf0=0x10" works perfectly.

Shall I splits all rules into bytes?
