net: atlantic: Fix NULL dereference of skb pointer in If is_ptp_ring == true in the loop of __aq_ring_xdp_clean function, then a timestamp is stored from a packet in a field of skb object, which is not allocated at the moment of the call (skb == NULL). Generalize aq_ptp_extract_ts and other affected functions so they don't work with struct sk_buff*, but with struct skb_shared_hwtstamps*.

net: aquantia: disable ptp object build if no config We do disable aq_ptp module build using inline stubs when CONFIG_PTP_1588_CLOCK is not declared. This reduces module size and removes unnecessary code.

net: aquantia: add support for PIN funcs Depending on FW configuration we can manage from 0 to 3 PINs for periodic output and from 0 to 1 ext ts PIN for getting TS for external event. Ext TS PIN functionality is implemented via periodic timestamps polling directly from PHY, because right now there is now way to receive the PIN trigger interrupt from phy. The polling interval is 15 milliseconds.

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.

net: aquantia: PTP skeleton declarations and callbacks Here we add basic function for PTP clock register/unregister. We also declare FW/HW capability bits used to control PTP feature on device. PTP device is created if network card has appropriate FW that has PTP enabled in config. HW supports timestamping for PTPv2 802.AS1 and PTPv2 IPv4 UDP packets. It also supports basic PTP callbacks for getting/setting time, adjusting frequency and time as well.
