Kernel 2.6.11, iproute2 version ss050330 (the same problem with version
ss010824)

tc filter add dev eth0 protocol ip parent 1:0 pref 100 u32 match u32 \
11223300 ffffff00 at 16 flowid 1:116
works fine and

tc filter add dev eth0 protocol ip parent 1:0 pref 100 u32 match u32 \
a1223300 ffffff00 at 16 flowid 1:116
gives:
Illegal "match"

Generally works fine when there are no letters in the match pattern.
Any ideas what is wrong ?
