Hi, I've noticed that VPP returns bad host IPv6 addresses from sw_interface_tap_v2_dump() API call. As it turned out, the problem is due to this line: https://github.com/FDio/vpp/blob/ef356f57b54b948d990b293514f062aebf86da72/src/vnet/devices/tap/tap.c#L743 with cxq_vring field belonging to the part of a union inside virtio_if_t that's only used for virtio_pci, but also coincides with host_ip6_addr in the other part of the union. As there are more code paths that use this field without checking virtio type, for example in virtio_show(), I thought it's probably safer to move it out of the union: https://gerrit.fd.io/r/c/vpp/+/33791 This patch fixes the issue with TAP details.
