From beb0b2e346c63e21ffe892ae0e04b67bb10fba5e Mon Sep 17 00:00:00 2001 From: John Lo Date: Sat, 22 Jul 2017 00:21:36 -0400 Subject: Improve L2 Input/Output Feature Infrastructure and Usage Simplify L2 output feature infra to unify with L2 input feature infra using the newly improved feature bitmap mechanism. Updated all L2 features to use the more efficient infra functions.
