    Subject: nft_test.cfg: Enable CONFIG_VETH
    Date: Wed, 10 Apr 2024 16:11:47 -0700

    nftable ptests do create interfaces of veth type and this
    feature would be needed to enable those tests

    e.g. from tests/shell/testcases/packetpath/vlan_8021ad_tag

    ip link add veth0 netns $ns1 type veth peer name veth0 netns $ns2
