[net-next,v2,2/3] net: ethernet: mtk_eth_soc: Use ipv6_addr_{cpu_to_be32,be32_to_cpu} helpers

Commit Message

Simon Horman Aug. 13, 2024, 1:33 p.m. UTC

Use ipv6_addr_cpu_to_be32 and ipv6_addr_be32_to_cpu helpers to convert
address, rather than open coding the conversion.

No functional change intended.
Compile tested only.
