Hi there,
I'm having a bit of a headache because of the u32 filter with hashing... My router administration system updates filter configuration differentially. Therefore I need to delete filters sometimes. I know that by deleting root class I'd make all filters go away, but I can't use that option in this particular case.
When I delete even a single u32 hashed filter I end up with non-functional u32 hashed filters. No band is classified by hashed u32 filters any more. The only thing that saves the day is a root class delete and full filter reload.
Test platform 1
---------------
tested kernels: 2.6.13.4 and 2.6.11-rc4 (both with SMP)
Hardware: 2 x Intel(R) Xeon(TM) CPU 2.40GHz with HT enabled
Test platform 2
---------------
tested kernels: 2.6.13.2
Hardware: AMD Athlon 900MHz
I don't know if it's important, but I'm using CPU cycle counter as a packet scheduler clock source on both systems.
Any comments? Should I go to the kernel dev group with this?
Cheers,
Marek Kierdelewicz
