After running command "ethtool -t eth0", eth0 can not be connected to
network. It is caused by the changing the inner loopback register and
this register cannot be changed when hns connected to network. The
routine of setting this register needs to be removed and using promisc
mode to let the packet looped back pass by dsaf mode.

In the Hip06 SoC, the RoCE Engine is part of the Hisilicon Network
Subsystem and is dependent upon DSAF module. Therefore, certain
functions like RESET are exposed through the common registers of
HNS DSAF module which are memory-mapped by the HNS driver and
currently can only be accessed through DT/syscon interface.
This patch adds the support of ACPI to the existing RoCE reset
function in the HNS driver(please refer NOTE 2). Hisilicon RoCE
driver (please refer NOTE 1) shall call this reset function during
probe time to reset the RoCE Engine.
The HNS Reset function indirectly ends up in calling the _DSM()
function part of the DSDT ACPI Table. Actual reset functionality
for ACPI is implemented within the ACPI DSDT Table which also has
been enhanced to support this change.
Support of ACPI in the HNS RoCE driver shall be pushed through a
different accompanying below patch:
"IB/hns: Add support of ACPI to the Hisilicon RoCE Driver"
NOTE 1: HNS RoCE driver has already been accepted by its maintainer
Doug Ledford<dledford@redhat.com>. Please refer below link:
https://www.spinics.net/lists/linux-rdma/msg38850.html
NOTE 2: RoCE reset function patch has been accepted and now is

This new firmware for the qed* adpaters fixes several issues:
- Better blocking of malicious VFs.
- After FLR, Tx-switching [internal routing] of packets might
be incorrect.
- Deletion of unicast MAC filters would sometime have side-effect
of corrupting the MAC filters configred for a device.
It also contains fixes for future qed* drivers that *hopefully* would be
sent for review in the near future.
In addition, it would allow driver some new functionality, including:
- Allowing PF/VF driver compaitibility with old drivers [running
pre-8.10.5.0 firmware].
- Better debug facilities.
This would also bump the qed* driver versions to 8.10.9.20.

10GbE Intel Wired LAN Driver Updates 2016-08-18
This series contains updates to ixgbe and ixgbevf.
Emil cleans up confusing amongst the users by making an error message
into a debug message, since the TXDCTL.ENABLE (and comparable
VFTXDCTL.ENABLE for ixgbevf) bit is set only when the
transmit queue is actually enabled, which may not happen during the
configure phase eve if we waited for it. Converts to using netdev_dbg()
macro instead of our home brewed macro for ixgbevf. Converted the

BCM53573 is a new series of Broadcom's SoCs. It's based on ARM and can
be found in two packages (versions): BCM53573 and BCM47189. It shares
some code with the Northstar family, but also requires some new quirks.
First of all there can be up to 2 Ethernet cores on this SoC. If that is
the case, they are connected to two different switch ports allowing some
more complex/optimized setups. It seems the second unit doesn't come
fully configured and requires some IRQ quirk.
Other than that only the first core is connected to the PHY. For the
second one we have to register fixed PHY (similarly to the Northstar),
otherwise generic PHY driver would get some invalid info.
This has been successfully tested on Tenda AC9 (BCM47189B0).
