Backport merged upstream patch that adds support for firmware loader
from NVMEM or attached filesystem for Aquantia PHYs.
Refresh all kernel patches affected by this change.
Also update the path for aquantia .ko that got moved to dedicated
directory upstream.

Subject: [PATCH] net: phy: add driver for MediaTek SoC built-in GE PHYs
|
|
|
|
Some of MediaTek's Filogic SoCs come with built-in gigabit Ethernet
|
|
PHYs which require calibration data from the SoC's efuse.
|
|
Despite the similar design the driver doesn't share any code with the
|
|
existing mediatek-ge.c.
|
|
Add support for such PHYs by introducing a new driver with basic
|
|
support for MediaTek SoCs MT7981 and MT7988 built-in 1GE PHYs.
