tcp: add option for always on event logging
Type: feature Add option to always compile in debugging infra. Debug verbosity can be controlled via configuration updatable via cli. Compile time inclusion and configuration of event logging verbosity is still available in order to minimize event logging impact. Change-Id: I9d946efe9fa4204fdace1adb1d6588c97b5ae758 Signed-off-by: Florin Coras <fcoras@cisco.com>
