Hi Maxime,-----Original Message----- From: dev <dev-boun...@dpdk.org> On Behalf Of Chenbo Xia Sent: Thursday, November 4, 2021 1:11 PM To: dev@dpdk.org Cc: maxime.coque...@redhat.com Subject: [dpdk-dev] [PATCH] examples/vhost: fix port init failure in mergeable mode When the example starts in mergeable mode with an i40e port, it fails to launch because the examples use default mtu MAX_MTU to configure ethdev. The root cause is some devices have Ethernet frame overhead and then MAX_MTU will be larger than device's max mtu, so the ethdev configure will fail. This patch checks the device's max mtu before setting the ethdev configuration. If the device has a max mtu, use that value to configure. Fixes: 1bb4a528c41f ("ethdev: fix max Rx packet length") Signed-off-by: Chenbo Xia <chenbo....@intel.com> Reported-by: Xingguang He <xingguang...@intel.com> ---I see a unit test failure on this patch, but I think this patch should not cause issues in unit test, could you help me confirm it?
I can confirm, mcslock_autotest is not related to your change, and it seems other patches are facing the same issue, eg:
