For the NET_LIST_FOR_EACH & NET_LIST_FOR_EACH_SAFE, "Entry" should be checked whether it's NULL or not instead of using the pointer directly. Besides, NET_LIST_FOR_EACH_SAFE is defined to iterate through the double linked list in delete-safe way. It's unnecessary to use this macro if list entries won't be deleted.
