Subject: [PATCH net-next] net: thunder: make tx software timestamp independent

From: Jason Xing <kernelxing@...cent.com>

skb_tx_timestamp() is used for tx software timestamp enabled by
SOF_TIMESTAMPING_TX_SOFTWARE while SKBTX_HW_TSTAMP is controlled by
SOF_TIMESTAMPING_TX_HARDWARE. As it clearly shows they are different
timestamps in two dimensions, this patch makes the software one
standalone.
