[LARTC] Useing HashTable

[LARTC] Useing HashTable

[zoop]

I have a quesiton about hashtables I'm trying to understan how I can use
this.
the default hash table would be 800::

tc filter add dev eth1 protocol ip parent 1:0 prio 5 u32 ht 800:: \
        match ip src 1.2.0.0/16 \
        hashkey mask 0x000000ff at 12 \
        link 2:

tc filter add dev eth1 protocol ip parent 1:0 prio 5 u32 ht 2:7b: \
        match ip src 1.2.4.123 flowid 1:2

so I would understand this to get the last octect of the IP address and
use it to choose the ht

I'm wondering if I could set the mask to something like 0x0000ff00 so that
I could only get the 3rd octect?  Or am I not understanding how the mask
works?
 and also could I use it like a normail netowrk mask so that I could use
something like 0x00000080 or something?

Would also work, yes.
