net/sched: Add separate check for skip_hw flag
Creating a difference between two possible cases: 1. Not offloading tc rule since the user sets 'skip_hw' flag. 2. Not offloading tc rule since the device doesn't support offloading. This patch doesn't add any new functionality. Signed-off-by: Hadar Hen Zion <hadarh@mellanox.com> Reviewed-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
