Subject: ethernet: sun: remove direct netdev->dev_addr writes
Patch-mainline: v5.16-rc1
Git-commit: a7639279c93c1e07a703c0f86f0831d4ea2314f0
References: jsc#PED-1565
Consify temporary variables pointing to netdev->dev_addr.
A few places need local storage but pretty simple conversion
over all. Note that macaddr[] is an array of ints, so we need
to keep the loops.
