Subject: [PATCH net-next] r8152: Advertise software timestamp information.

From: Abhishek Rawal <rawal.abhishek92@...il.com>

Driver calls skb_tx_timestamp(skb) in rtl8152_start_xmit(), but does not advertise the capability in ethtool.
Advertise software timestamp capabilities on struct ethtool_ops.
