Hello,
The attached patch fixes the non-working mirroring feature in all recent
versions of the i40e driver including the latest (2.9.21).
Simply put, using
echo 'add 3' > /sys/class/net/eth10/device/sriov/1/ingress_mirror
fails because it passes down the AQ a 0x0260 command with the same SEID (that of
VF 3) as both mirrored-from and mirrored-to VF.
This was reported to the sourceforge e1000 projet a few days ago as
https://sourceforge.net/p/e1000/bugs/646/
but I'm following advice given there to send it to you for a "fast track" as the
repro and diagnosis is trivial and fix already provided.
Hope this helps,
-Alex
