Hi,
I'm trying to delete filters from a hashtable programatically, but am
being foiled by one small problem:

I can delete the rule with no difficulty given the full handle like so:
tc filter del dev eth2 pref 5 handle 2:fe:800 u32

First, my understanding is that, in this case:
2 => table
fe => column
800 =>row (or vice versa)
Is this correct?

Given that, I suppose I need to know how to delete an entry without
knowing which row it was inserted into. Alternatively, can I explicitly
set the row into which I am inserting? Here is what I'm doing now:

 tc filter add dev eth2 parent 1:0 protocol ip prio 1 u32 ht 2:fe: match
ip dst 192.168.255.254/32 flowid 1:fe; (Where, notably, "fffe" is the
last two octets of the IP, and fe is the last.)

Any help would be *much* appreciated. My brain is starting to melt ;)
