TCAM / ACL usage on 7050X3

Managed to fit 225 complex ACL entries like "10 permit tcp host host range 1100 1199" (randomized port ranges) in hardware causing 99.8% TCAM usage:

#show platform trident tcam
TCAM group 10 uses 1533 entries and can use up to 3 more.
Router ACL uses 1533 entries.

R-series should be able to fit more than 10X more (not tested)
