This is not mandatory as per +IPMI Spec, and we must support individual fields update. +Fix: +1. After SET_COMPLETE for parameter selector, changes has +to be applied immediately, and doesn't require to rely on +network timer, as purpose of this logic itself is to stage +and commit. +2. Allow individual parameter changes to take effect based +on timer. For the time being reduced the timer to 5 sec +to have quicker turn-around and group things together. + +TODO: +Still need to introduce lock between ChannelConfig variable +between Timer & Get / Set LAN Configuration command to avoid +race condition + +Unit-Test: +1.
