Subject: [PATCH net-next v2 0/3] misc drivers' sw timestamp changes

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

This series modified three outstanding drivers among more than 100 drivers
because the software timestamp generation is too early. The idea of this
series is derived from the brief talk[1] with Willem. In conclusion, this
series makes the generation of software timestamp near/before kicking the
doorbell for drivers.

1. remove lan966x patch since it breaks PHY timestamping.
2. move skb_tx_timestamp() earlier than before in cxgb4_eth_xmit() to
avoid skb being orphaned/consumed.
3. revise the commit log.

  net: atlantic: generate software timestamp just before the doorbell
  net: cxgb4: generate software timestamp just before the doorbell
  net: stmmac: generate software timestamp just before the doorbell
