Based on your previous focus on Linux dual-sensor PTP high-precision synchronization scenarios, the mainstream network card drivers supporting hardware timestamps are as follows:
igb driver: Adapted to Intel I210/I350 series gigabit industrial network cards, this is the most commonly used driver for PTP scenarios, natively supporting hardware timestamps and offering the most stable compatibility.
ixgbe driver: Adapted to Intel 82599/X520 series 10-gigabit network cards, supporting PTP hardware timestamps, suitable for high-bandwidth, high-synchronization-precision dual-sensor scenarios.
tg3 driver: Adapted to Broadcom BCM57xx series enterprise-grade network cards, natively supporting hardware timestamps, with compatibility covering most industrial motherboard integrated network cards.
e1000e driver: Adapted to Intel I217/I218 series consumer-grade gigabit network cards, some versions support basic hardware timestamps, suitable for low-cost entry-level scenarios.
These drivers are all verified via the PTP protocol and can directly enable the hardware timestamp function, supporting microsecond-level synchronization of dual sensors.
