Series ipv6: Add ipv6_addr_{cpu_to_be32,be32_to_cpu} helpers | expand

Commit Message

Simon Horman Aug. 13, 2024, 1:33 p.m. UTC 
Use new ipv6_addr_cpu_to_be32 and ipv6_addr_be32_to_cpu helpers,
and IPV6_ADDR_WORDS. This is arguably slightly nicer.

No functional change intended.
Compile tested only.
