[PATCH net-next 0/3] ipv6: Add ipv6_addr_{cpu_to_be32,be32_to_cpu} helpers

[Simon Horman]

Hi,

This series adds and uses some new helpers,
ipv6_addr_{cpu_to_be32,be32_to_cpu}, which are intended to assist in
byte order manipulation of IPv6 addresses stored as as arrays.

[PATCH net-next 1/3] ipv6: Add ipv6_addr_{cpu_to_be32,be32_to_cpu} helpers

[Simon Horman]

Add helper to convert an ipv6 addr, expressed as an array
of words, from cpy to big-endian byte order.

No functional change intended.
Compile tested only.

Hi Simon

Is cpy supposed to be cpu?

Otherwise, please add: Reviewed-by: Andrew Lunn <andrew@lunn.ch>

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

[Simon Horman]

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.

[PATCH net-next 3/3] net: hns3: Use ipv6_addr_{cpu_to_be32,be32_to_cpu} helpers

[Simon Horman]

Use new ipv6_addr_cpu_to_be32 and ipv6_addr_be32_to_cpu helper,
and IPV6_ADDR_WORDS. This is arguably slightly nicer.

No functional change intended.
