Hi all,
Has anyone tried modifying the ixgbe PMD driver to allow an Intel X550 card to
insert the extra 8 bytes of data at the end of each receive message, the 8
bytes containing the receive SYSTIME timestamp ?
I've adjusted TYPE in TSYNCRXCTL to be "all packets" and set TSIP_UT_EN. I get
the 8 bytes of data appended to all packets, but the controller doesn't
populate the memory - the contents are left unchanged when transmitted.
TS and TSIP are both set in the received RDESC descriptor (along with the
receive byte count increasing by 8 bytes) so the adaptor is definitely doing
something.
Any ideas anyone ?
Many thanks
Terry.
