From: Marek Kasiewicz <[email protected]> When PTP is enabled on the ICE PMD, hardware RX timestamps are only applied to packets classified as IEEE 1588 (Ethertype 0x88F7). This prevents applications from obtaining hardware timestamps on regular UDP/IP traffic.
Remove the TIMESYNC packet type filter so that all received packets get hardware timestamps when PTP is enabled. This is required for time-sensitive networking applications that need per-packet arrival timing on media traffic, such as ST 2110-21 receiver compliance monitoring. The change affects all three RX paths: scan, scattered, and single packet receive functions.
