[PATCH net-next 4/4] r8152: Add firmware upload capability for RTL8157/RTL8159

[Birger Koblitz]

The RTL8159 requires firmware for its PHY in order to work at
connection speeds > 5GBit. Add support for uploading firmware for
the PHYs using the existing rtl8152_apply_firmware() function
in r8157_hw_phy_cfg() and set up the correct names for the firmware
files.

If no firmware is found, both the RTL8157 and the RTL8159 will continue
to work.
