Re: [Linuxptp-users] ptp4l stop with ANNOUNCE_RECEIPT_TIMEOUT_EXPIRES message.

Hello,

Yes, EG20T MAC drops UDP multicast in the situation. I think linuxptp seems
starting with promiscuous mode and leaves the promiscuous mode in the
situation.

However I can not see the any code about promiscuous mode in the linuxptp
> source code.

I found the issue in EG20T GbE driver. It does not support
set_multicast_list. Therefore EG20T GbE driver did not get multicast
message without promiscuous mode.
I am implementing the feature now.
After that I will try the test again.

Thank you for the advice.

Thanks and Best regards,
Takahiro Shimizu
