| |
This driver is a single standalone driver and does not have any loading dependencies on another associated drivers. The build results in one single .ko object. The current implementation of the function ieee80211_tkip_null simply returns back to the caller without any useful instruction executions. It does not lead to auto-loading of any other associated modules as the initial design implementation appears to be.
Hence the call to ieee80211_tkip_null() and its implementation is unnecessary and should be removed.
