LARTC - Nov 2005 - tc filter: match tcp src vs. match ip sport

Hi all :))

    This matches what I want:

    tc filter add dev eth0 protocol ip parent 1:0 prio 9 u32\
        match ip sport 0x3000 0xf000 flowid 1:22

    and traffic goes to 1:22, but this one doesn''t match:

    tc filter add dev eth0 protocol ip parent 1:0 prio 9 u32\
        match tcp src 0x3000 0xf000 flowid 1:22

    I don''t understand why the first one matches and the second one
doesn''t :? because in the output of "tc filter show" the only
difference is that the first one matches "at 20" and the second one
"at nexthdr+0", which should be identical :?????

    What the heck am I doing wrong? Thanks a lot :)
