2020-08-28ionic: change the descriptor ring length without full resetShannon Nelson3-14/+185
The original way of changing ring length was to completely tear down the lif's queue structure and then rebuild it, while running the risk of allocations that might fail in the middle and leave us with a broken driver. Instead, we can set up all the new queue and descriptor allocations first, then swap them out and delete the old allocations. If the new allocations fail, we report the error, stay with the old setup and continue running. This gives us a safer path, and a smaller window of time where we're not processing traffic.

2020-08-28ionic: change mtu without full queue rebuildShannon Nelson1-8/+49
We really don't need to tear down and rebuild the whole queue structure when changing the MTU; we can simply stop the queues, clean and refill, then restart the queues. Signed-off-by: Shannon Nelson <snelson@pensando.io> Signed-off-by: David S. Miller <davem@davemloft.net>

2020-08-28net: phy: DP83822: Add ability to advertise Fiber connectionDan Murphy1-7/+218
The DP83822 can be configured to use a Fiber connection. The strap register is read to determine if the device has been configured to use a fiber connection. With the fiber connection the PHY can be configured to detect whether the fiber connection is active by either a high signal or a low signal. Fiber mode is only applicable to the DP83822 so rework the PHY match table so that non-fiber PHYs can still use the same driver but not call or use any of the fiber features.

2020-08-24octeontx2-af: Add support for Marvell PTP coprocessorAleksey Makarov6-4/+348
Precision Timestamping block found on Octeontx2 platform is an independent coprocessor and has internal PTP hardware clock. Once configured PTP runs independently and when a packet arrives CGX hardware block gets the current timestamp from PTP block and forwards the packet to NIX by prepending timestamp to the packet. This patch adds the pci driver for PTP block. The driver gets registered by AF driver and does initial configuration and exposes a mailbox function to read and adjust PTP hardware clock. The mailbox function is called by AF consumers like netdev drivers or userspace drivers. Since PTP being a single block in platform this driver helps in accessing PTP block by any AF consumer.
