Subject: [dpdk-users] I40e - vlan packets are dropped when not setting MTU
Date: Sun, 24 Jan 2021 08:43:58 +0000 [thread overview]
Message-ID: <5588F99C-496A-4DBB-BD5D-843B6C78CD39@catonetworks.com> (raw)
Hey all,
I’m having trouble receiving vlan packets with IP length bigger than 1496 Bytes on i40e driver.
I have seen this thread https://mails.dpdk.org/archives/dev/2019-October/146908.html and indeed, after calling rte_eth_dev_set_mtu with mtu=1500, it works. I don’t understand why I have to use jumbo frames for that. I have tried it with different drivers (ixgbe) and no action beside rte_eth_dev_configure is required.
Using DPDK 16.11.1, but also reproduced on 17.11.3
thanks
