Subject: [PATCH] net: ethernet: ti: add NETIF_F_HW_TC hw feature flag for taprio offload

From: Murali Karicheri <m-karicheri2@...com>

Currently drive supports taprio offload which is a tc feature offloaded
to cpsw hardware. So driver has to set the hw feature flag, NETIF_F_HW_TC
in the net device to be compliant. This patch adds the flag.
