Hi William,

I tried running my PVP test, and with this patchset, I could not see the deadlock I used to see with all the previous patches.

However there is still the issue that the maximum packet size supported is 1028 bytes, all larger packets are dropped!!

I tested this patch with packets up to 1460 with iperf over the veth pair
and it works fine. Most likely, you caught some kernel driver issue.

Quickly tried the port to port test, and I see the issue there. So I assume it’s related to the physical port, which in my case is the following:

Bus info          Device       Class          Description
=========================================================
pci@0000:01:00.0 eno1 network 82599ES 10-Gigabit SFI/SFP+ Network Connection

I’m using the bpd-next tree @ commit 80f232121b69cc69a31ccb2b38c1665d770b0710



Unfortunately, I’m going on PTO Thursday till August so won’t be able to further test/review the v14. I’ll pick thinks up once I return from PTO.

Cheers,

Eelco
