[PATCH 05/10 net-next v3] drivers: net: drop ipv6_stub usage and use direct function calls

Fernando Fernandez Mancera
2026-03-17T14:03:51Z

As IPv6 is built-in only, the ipv6_stub infrastructure is no longer
necessary.

Convert all drivers currently utilizing ipv6_stub to make direct
function calls. The fallback functions introduced previously will
prevent linkage errors when CONFIG_IPV6 is disabled.
