Summary

  • Adds missing --ipv6 flag to the IPVLAN L3 dual-stack network creation example
  • Without this flag, Docker defaults to EnableIPv6: false even when an IPv6 subnet is specified
  • The L2 dual-stack example already includes this flag; this makes the L3 example consistent

Fixes #19337

🤖 Generated with Claude Code

The L3 dual-stack IPVLAN example omitted the --ipv6 flag when creating
the network, causing Docker to default to EnableIPv6: false despite an
IPv6 subnet being specified. The L2 example already includes this flag.

Fixes docker#19337
