    mlxsw: spectrum_acl: Add A-TCAM rule insertion and deletion · a8758b67
    Ido Schimmel authored
    Implement rule insertion and deletion into the A-TCAM before we flip the
    driver to start using the A-TCAM.
    
    Rule insertion into the A-TCAM is very similar to C-TCAM, but there are
    subtle differences between regions of different sizes (i.e., different
    number of key blocks).
    
    Specifically, as explained in "mlxsw: spectrum_acl: Allow encoding a
    partial key", in 12 key blocks regions a rule is split into two and the
    two halves of the rule are linked using a "large entry key ID".
    
    Such differences are abstracted away by using different region
    operations per region type.
