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. Signed-off-by: Christian Marangi <ansuelsmth@gmail.com>

Subject: [PATCH] drivers: net: phy: aquantia: enable AQR112 and AQR412
|
|
|
|
Adds support for AQR112 and AQR412 which is mostly based on existing code
|
|
with the addition of code configuring the protocol on system side.
|
|
This allows changing the system side protocol without having to deploy a
|
|
different firmware on the PHY.
