Hi Bruce,
yes, you are absolutely right. That resolves the problem.
I was really happy to see that DPDK 1.8 includes proper default
configurations for each driver and I made use of this. But unfortunately
I was not aware that the default configuration did include the
ETH_TXQ_FLAGS_NOMULTSEGS flag
Hi Bruce,
I now had the chance to reproduce the issue we are seeing with a DPDK
example app.
I started out with a vanilla DPDK 1.8.0 and only made the following changes:
diff --git a/examples/l2fwd/main.c b/examples/l2fwd/main.c
index e684234..48e6b7c 100644
--- a/examples/l2fwd/main.c

Prashant Upadhyaya with the subject 'Packet Rx issue with DPDK1.8'.
In our application we use the following rxmode port configuration:
.mq_mode=
Hi everybody,
we quite recently updated one of our applications to DPDK 1.8.0 and are
now seeing a segmentation fault in ixgbe_rxtx_vec.c:444 after a few minutes.
I just did some quick debugging and I only have a very limited
