net: aquantia: add PTP rings infrastructure
Add implementations of PTP rings alloc/free. PTP desing on this device uses two separate rings on a separate traffic class for traffic rx/tx. Third ring (hwts) is not a traffic ring, but is used only to receive timestamps of the transmitted packets. Signed-off-by:Egor Pomozov <epomozov@marvell.com> Co-developed-by:
