H A D | bnxt_ptp.h | 7f5515d1 Sun Jun 27 12:19:48 CDT 2021 Pavan Chebbi <pavan.chebbi@broadcom.com> bnxt_en: Get the RX packet timestamp
If the RX packet is timestamped by the hardware, the RX completion record will contain the lower 32-bit of the timestamp. This needs to be combined with the upper 16-bit of the periodic timestamp that we get from the timer. The previous snapshot in ptp->old_timer is used to make sure that the snapshot is not ahead of the RX timestamp and we adjust for wrap-around if needed.
v2: Make ptp->old_time read access safe on 32-bit CPUs.
