| |
The socfpga sub-driver defines an `interface` field in the `socfpga_dwmac` struct and parses it on init.
The shared `stmmac_probe_config_dt()` function also parses this from the device-tree and makes it available on the returned `plat_data` (which is the same data available via `netdev_priv()`).
All that's needed now is to dig that information out, via some `dev_get_drvdata()` && `netdev_priv()` calls and re-use it.
Signed-off-by: Alexandru Ardelean <alexandru.ardelean@analog.com> --- Changelog v2 -> v3: * drop `inline` keyword
Changelog v1 -> v2: * initially, this patch was developed on a 4.14 kernel, and adapted (badly) to `net-next`, so it did not build ; the v2 has been fixed and adapted correctly
