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

From: Simon Horman
Date: Tue Aug 13 2024 - 09:35:05 EST


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.
