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 ;)
