acl: add API call for setting the toggle to select between linear and bihash-based lookups
In some cases (ACL of a few lines long with a lot of different subnet masks), linear lookup may be more efficient than the hash-based lookup. Expose the API to allow the control plane to choose what lookup algorithm to use. Type: improvement Change-Id: I540dd1b4ce63c5106a556d550f911f3a578b33e0 Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com>
