Subject[PATCH] net: add new QCA alx ethernet driver which supercedes atl1c
Date
This driver is intended to replace the atl1c driver and provide
support for a two new chipsets. Qualcomm Atheros (QCA) is commiting
to fixing all bugs found on this driver. Test results show this
driver performs better than atl1c on all supported chipsets, closes
the gap between TX and RX throughput (they now match) and has also
been verified with ASPM enabled on all supported chipsets. This
driver and patch also have addressed all sparse and checkpatch
warnings.

QCA is commiting on fixing all bugs upstream on this driver.
This driver is also permissively licensed thereby enabling
developers of other OSes to cherry pick this driver to port to
their OS, such as FreeBSD.

Both atl1c and alx driver support the following chipsets:

1969:1063 - AR8131 Gigabit Ethernet
1969:1062 - AR8132 Fast Ethernet (10/100 Mbit/s)
1969:2062 - AR8152 v2.0 Fast Ethernet
1969:2060 - AR8152 v1.1 Fast Ethernet
1969:1073 - AR8151 v1.0 Gigabit Ethernet
1969:1083 - AR8151 v2.0 Gigabit Ethernet

But alx also supports these two new chipstes:

1969:1091 - AR8161 Gigabit Ethernet
1969:1090 - AR8162 Fast Ethernet

We leave the atl1c driver in place for now but mark it as
deprecated in favor for the alx. Linux distributions should
consider using alx moving forward and any issues found with
the alx driver will be proactively addressed and tracked by
assigned by QCA engineers.

For more detail including a shiny graph of throughput in comparison
to atl1c see the new shiny alx driver home page:
