Just a quick guess, but why are you bothering with this: match ip src
0/0 match ip dst 0/0
It's very likely that is causing the invalid argument error, and
doesn't seem necassary at all.  Should at least try the more
simplified command:
tc filter add dev eth1 parent 1:0 protocol ip prio 1 u32 match ip
sport 80 0xffff flowid 1:10
