net: dsa: mv88e6xxx: Release mutex between each ATU read The PTP code needs low latency access to the PTP hardware timestamps. Reading all the ATU entries in one go adds a lot of latency to the PTP code. So take and release the reg_lock mutex for each individual MAC address in the ATU, allowing the PTP thread jump in between. Signed-off-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S.
