By dropping the filter on prefix length, commit910f4f9103("test: Don't require 64-bit prefixes in perf tests") broke tests on setups where two global unicast IPv6 addresses are available, which is the typical case when the "host" is a VM running under passt with addresses from SLAAC and DHCPv6, because two addresses will be returned. Pick the first one instead. We don't really care about the prefix length, any of these addresses will work. Fixes:910f4f9103("test: Don't require 64-bit prefixes in perf tests") Link: https://archives.passt.top/passt-dev/20241119214344.6b4a5b3a@elisabeth/ Signed-off-by: Stefano Brivio <sbrivio@redhat.com> Reviewed-by: David Gibson <david@gibson.dropbear.id.au>
