Subject: [LARTC] u32 filter usage

Hi All,

About u32 usage, as I know the following 3 syntax should be the same:
 1. tc filter add ........u32\
     match ip protocol 0x6 0xff 

2. tc filter add ........u32\
    match 00060000 00ff0000 at 9

3. tc filter add ..........u32\
    match u8 6 0xff at 10

However, in my platform (Linux2.4.2), only method 1 works.  Besides, as I
show the filter (tc filter ls dev eth1),
it gives me " match 00060000 00ff0000 at 9", which matches with method 2.

So can any one explain why method 2 and 3 can't work (it shows the message
"illegal match") ?

Best Regards
