Public bug reported:

Binary package hint: iproute

$ lsb_release -rd
Description:    Ubuntu Natty (development branch)
Release:        11.04

The filter settings for dport get printed out as sport settings and vice
versa when the -p option is specified for the command.

This issue happens for dport, sport, and dport/sport cases.  See example
below.

$ tc filter show dev eth0
$ sudo tc filter add dev eth0 protocol ip prio 1 u32 match ip protocol 17 0xff 
match ip dport 3055 0xffff match ip dst 192.168.91.38 flowid 1:11
$ tc filter show dev eth0
filter parent 1: protocol ip pref 1 u32 
filter parent 1: protocol ip pref 1 u32 fh 800: ht divisor 1 
filter parent 1: protocol ip pref 1 u32 fh 800::800 order 2048 key ht 800 bkt 0 
flowid 1:11 
  match 00110000/00ff0000 at 8
  match 00000bef/0000ffff at 20
  match c0a85b26/ffffffff at 16
$ tc -p filter show dev eth0
filter parent 1: protocol ip pref 1 u32 
filter parent 1: protocol ip pref 1 u32 fh 800: ht divisor 1 
filter parent 1: protocol ip pref 1 u32 fh 800::800 order 2048 key ht 800 bkt 0 
flowid 1:11 
  match IP protocol 17
  match sport 3055
  match IP dst 192.168.91.38/32
