PTP support on AQC107

[vvv-ca]

Hi,

I'm trying to get PTP working on a QNAP QNA-T310G1S adapter which uses the AQC107 chip but ethtool returns no support whatsoever:

ethtool -T ens4
Time stamping parameters for ens4:
Capabilities:
        software-transmit
        software-receive
        software-system-clock
PTP Hardware Clock: none
Hardware Transmit Timestamp Modes: none
Hardware Receive Filter Modes: none

This is with module build from master here and 5.7.10-1 kernel. Chip is on firmware 3.1.109, ethtool is version 5.8

driver: atlantic
version: 5.7.0-2-amd642.4.7.0
firmware-version: 3.1.109
expansion-rom-version: 
bus-info: 0000:0a:00.0
supports-statistics: yes
supports-test: yes
supports-eeprom-access: no
supports-register-dump: yes
supports-priv-flags: yes

Is there anything I can do to troubleshoot this? Thanks!

Plz either use latest kernel, or out of box driver from github.

But I did use the out of box driver from github:

version: 5.7.0-2-amd642.4.7.0

No, this version indicates thats a inbox. OOB should have 2.4.3

I built it from this github repo code which is 2.4.7. 2.4.3 is the code on the Marvell site. For whatever reason, the ethtool -i command pre-pends the kernel version to the driver version and reports the driver version as 5.7.0-2-amd642.4.7.0. Here is the modinfo as well:

For future reference, the QNA-T310G1S uses the AQC100S which is a Ethernet MAC with no PTP support. The AQC100S seems to connect directly to the SFP modules via XFI so no PHY either. Thus no PTP support. It does seem like the driver should provide at least software PTP timestamps.
