Thanks for the response.
LPM is actually the closest solution however I wanted a structure closer to the way TCAMs operate in which you can have wildcards also in the interim bits.
I believe that something like that does not exist and I need to implement it using available structures in

Right, BPF does not have TCAM style maps. If you organize data
structure properly, you may be able to use LPM.

Hi all, I am trying to find a way to represent wildcards in BPF Map Keys?
I could not find anything relevant to that, does anyone know anything further.
Are there any efforts towards that functionality?
The closest map is lpm (trie) map. You may want to take a look.
