# Wangxun WX1820 (txgbe) — evaluated, disqualified
|
|
|
|
- Module I2C is architecturally ideal: kernel `sff`/phylink exposes `/dev/i2c-N` — arbitrary framing, zero patches.
|
|
- **Disqualified as product NIC**: PTP-only RX timestamping (verified in upstream `wx_ptp.c` — `HWTSTAMP_FILTER_ALL` falls to -ERANGE), the same limitation as the 82599 with a younger driver.
|
|
- Flow-steering/counter parity unverified.
