2018-03-04dsa: Pass the port to get_sset_count()Andrew Lunn1-1/+1
By passing the port, we allow different ports to have different statistics. This is useful since some ports have SERDES interfaces with their own statistic counters.

2018-02-14net: dsa: forward timestamping callbacks to switch driversBrandon Streiff1-0/+5
Forward the rx/tx timestamp machinery from the dsa infrastructure to the switch driver. On the rx side, defer delivery of skbs until we have an rx timestamp. This mimicks the behavior of skb_defer_rx_timestamp. On the tx side, identify PTP packets, clone them, and pass them to the underlying switch driver before we transmit. This mimicks the behavior of skb_tx_timestamp.

2017-12-05net: dsa: return per-port upstream portVivien Didelot1-3/+6
The current dsa_upstream_port() helper still assumes a unique CPU port in the whole switch fabric. This is becoming wrong, as every port in the fabric has its dedicated CPU port, thus every port has an upstream port. Add a port argument to the dsa_upstream_port() helper and fetch its CPU port instead of the deprecated unique fabric CPU port. A CPU or unused port has no dedicated CPU port, so return itself in this case. At the same time, change the return value from u8 to unsigned int since there is no need to limit the size here.
