Re: [Linuxptp-users] [Linuxptp-devel] [PATCH] sk: update error message for Tx timestamp polling

[Arnold k. <arn...@gm...>]

hi Richard,
   i just use a test code  from kernel
https://www.kernel.org/doc/Documentation/networking/timestamping/timestamping.c.
and i can receive the send package timestamp back. i i guess this is a
bug in linux ptp. can you tell me how to resolve it?


thanks.
