[PATCH v2 net-next 7/7] net: ethernet: update drivers to make both SW and HW TX timestamps
From: Miroslav Lichvar <hidden>

Some drivers were calling the skb_tx_timestamp() function only when a hardware timestamp was not requested. Now that applications can use the SOF_TIMESTAMPING_OPT_TX_SWHW option to request both software and hardware timestamps, the drivers need to be modified to unconditionally call skb_tx_timestamp().
