Re: [Linuxptp-users] Irregular rate of Delay Request messages

[Ray V. <ree...@gm...>]

I use a I219-LM chip with the e1000e driver:
> ethtool -i eth1
driver: e1000e
version: 2.3.2-k
firmware-version: 0.8-4
expansion-rom-version:
bus-info: 0000:00:1f.6
supports-statistics: yes
supports-test: yes
supports-eeprom-access: yes
supports-register-dump: yes
supports-priv-flags: no

Which is rather old, I see... (I'm stuck to an also rather old Fedora Core
25 linux).
On the other hand, the sources include a ptp.c file from/by Richard
Cochran...
Is this version flagged as buggy?
