Hello Sinij, Thank you for posting in Intel® Ethernet Community. We have Intel Ethernet Network Adapter X710 and XL710 Series that supports QinQ. You can refer to this link for the list of Intel Network Adapters, and please take note that only X710 and XL710 Series supports QinQ. https://www.intel.com/content/www/us/en/products/network-io/ethernet/10-25-40-gigabit-adapters.html For additional information please refer to details below from the X710 driver readme file - https://downloadmirror.intel.com/24411/eng/readme.txt IEEE 802.1ad (QinQ) Support --------------------------- The IEEE 802.1ad standard, informally known as QinQ, allows for multiple VLAN IDs within a single Ethernet frame. VLAN IDs are sometimes referred to as "tags," and multiple VLAN IDs are thus referred to as a "tag stack." Tag stacks allow L2 tunneling and the ability to segregate traffic within a particular VLAN ID, among other uses. The following are examples of how to configure 802.1ad (QinQ): ip link add link eth0 eth0.24 type vlan proto 802.1ad id 24 ip link add link eth0.24 eth0.24.371 type vlan proto 802.1Q id 371 Where "24" and "371" are example VLAN IDs. NOTES: - 802.1ad (QinQ)is supported in 3.19 and later kernels. - Receive checksum offloads, cloud filters, and VLAN acceleration are not supported for 802.1ad (QinQ) packets. Please let me know if you have any other questions. Best regards, Crisselle C Intel Customer Support Under contract to Intel Corporation
