Bug 249186: ports-mgmt/pkg: pkg upgrade extremely slow with IPv6
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=249186



--- Description ---
Experienced on 12.1-p8, amd64. Simple pkg upgrade can take several hours when
IPv6 is enabled. Switching to IPv4 (with ip6addrctl) immediately speeds up the
operation.
