Merge branch 'tc-bind_class-hook'
Zhengchao Shao says: ==================== refactor duplicate codes in bind_class hook function All the bind_class callback duplicate the same logic, so we can refactor them. First, ensure n arg not empty before call bind_class hook function. Then, add tc_cls_bind_class() helper. Last, use tc_cls_bind_class() in filter. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
