As device_node is only used by DT case, HNS needs to treat the other cases including ACPI. It needs to use uniform ways to handle both of DT and ACPI. This patch chooses phy_device, and of_phy_connect and of_phy_attach are only used by DT case. It needs to use uniform interface to handle that sequence by both DT and ACPI.

hns-mdio needs to register itself to mii-bus. The info of the device can be read by both DT and ACPI. HNS tries to call Linux PHY driver to help access PHY-devices, the HNS hardware topology is as below. The MDIO controller may control several PHY-devices, and each PHY-device connects to a MAC device. The MDIO will be registered to mdiobus, then PHY-devices will register when each mac find PHY device. cpu | | ------------------------------------------- | | | | | | | dsaf | MDIO | MDIO | --------------------------- | | | | | | | | | | | | | | MAC MAC MAC MAC | | | | | | | ---- |-------- |-------- | | -------- || || || || PHY PHY PHY PHY And the driver can handle reset sequence by _RST method in DSDT in ACPI case.

Andrew Lunn says: ==================== New DSA bind, switches as devices The interesting patches here are the last three. They implement a new binding for DSA, which removes a few limitations of the current DSA binding. In particular, it allows switches to be true Linux devices. These devices can be on any type of bus, unlike the old DSA binding which assumes MDIO. See the commit log for more details. The second to last patch modifies an existing boards device tree to use the new binding, giving a good example of how switches can be true MDIO devices. The last patch documents the new binding. Thanks go to Florian and Vivien for reviewing, testing and bug fixing these patches.

The existing DSA binding has a number of limitations and problems. The main problem is that it cannot represent a switch as a linux device, hanging off some bus. It is limited to one CPU port. The DSA platform device is artificial, and does not really represent hardware. Implement a new binding which can be embedded into any type of node on a bus to represent one switch device, and its links to other switches.

The switch implements a generic MDIO bus, which could host more than PHYs. It is conventional to use _mdio_ or _mii_ in the function name, so rename them. Also postfix make the historically first read/write function with _direct, to help distinguish it from _indirect and _ppu. While touching these functions, remove some of the _ prefixes, which we are deprecating.

Move the port device node structure into the port structure, from the chip data. This information is needed in the next step of implementing the new binding. The chip data structure is used while parsing the whole old binding, before the individual switch structures exist. With the new bindings, this is reversed, the switches exist first, and the interconnections between the switches is derived from the individual switch bindings. Thus this chip data structure becomes unneeded.

Yuval Mintz says: ==================== qed: RocE & iSCSI infrastructure We plan on sending 2 new protocol drivers in the imminent future - both our RoCE [qedr] and iSCSI [qedi] drivers. As both submissions would be rather massive and in order to avoid collisions between them, the common infrastructure on the qed side was prepared as an independent patch-series to be sent ahead of those 2 submissions. This patch series introduces in QED 2 new 'ids' - one for iscsi and one for roce. It then goes and adds logic required for configuring said protocols in HW. Notice it *doesn't* actually add any client using said ids, but rather only the infrastructure to allow their later usage. What this patch doesn't contain is the slowpath protocol-configuration toward the firmware. I.e., it contains register-setting logic, memory allocations, etc., but not actual flow-related configuration specific to the protocl. Those would be sent as part of the protocol driver submissions. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

RoCE and iSCSI would require some added/changed hw configuration in order to properly run; The biggest single change being the requirement of allocating and mapping host memory for several HW blocks that aren't being used by qede [SRC, QM, TM, etc.]. In addition, whereas qede is only using context memory for HW blocks, the new protocol would also require task memories to be added.

RoCE driver is going to need a 32-bit chain [current chain implementation for qed* currently supports only 16-bit producer/consumer chains]. This patch adds said support, as well as doing other slight tweaks and modifications to qed's chain API. Signed-off-by: NYuval Mintz <Yuval.Mintz@qlogic.com> Signed-off-by: NDavid S.

Marcelo Ricardo Leitner says: ==================== sctp: Add GSO support This patchset adds sctp GSO support. Performance tests indicates that increases throughput by 10% if using bigger chunk sizes, specially if bigger than MTU. For small chunks, it doesn't help much if not using heavy firewall rules. For small chunks it will probably be of more use once we get something like MSG_MORE as David Laight had suggested. overall changes: v1->v2: Added support for receiving GSO frames on SCTP stack, as requested by Dave Miller. v2->v3: Consider sctphdr size in skb_gso_transport_seglen() rebased due to 5c7cdf33 ("gso: Remove arbitrary checks for unsupported GSO") ==================== Signed-off-by: NDavid S.
