> In ixgbe_configure_clsu32(), 'jump', 'input', and 'mask' are allocated through
> kzalloc() respectively in a for loop body. Then,
> ixgbe_clsu32_build_input() is invoked to build the input. If this process fails,
> next iteration of the for loop will be executed. However, the allocated
> 'jump', 'input', and 'mask' are not deallocated on this execution path, leading
