Hi Ehrhardt, 
Failed build DPDK with "Make", we have a patch to fix it and sent to stable@dpdk.org and we are verifying this patch.

Patch " [PATCH] net/ixgbe: fix configuration of max frame size" has sent to stable@dpdk.org by Alvin Zhang <alvinx.zhang@intel.com>. We have verified the patch in local. You can find it.

Currently, most of the test are executed. Left part are blocked by 2 issues.
1. Build dpdk failed with make: patch is provided by Intel Dev. We are verifying it. If okay, will finish the test left blocked by this issue.
2. Test_cryptodev_scheduler_autotest: Command not found after using meson/ninja build:  it blocked 7 function test cases and scheduler PMD 3CPMs performance test. Intel are working on this but maybe it can be fixed in this 19.11.7 release cycle.
