Subject: Re: tc filter add with handle 800::10:800

In-Reply-To: CAE_-sdmpSSNEt5R2B+v1FaSP+SYCk_khW2KieRL_7xVbR=nfHw

Hi there!

I just understand how it works?
And I want to control by myself which hash table number will be set
tc filter replace dev eno5 parent ffff: pref 49100 handle 800:10:800
protocol ip u32 match u8 0 0

and then I'll can delete this filter by command like this
tc filter delete dev eno5 parent ffff: pref 49100 handle 800:10:800 u32

And then create that filter again by command
tc filter replace dev eno5 parent ffff: pref 49100 handle 800:10:800
protocol ip u32 match u8 0 0

Is it possible ?

I pleased for your help?
