* vmxnet3: allow variable length transmit data ring bufferShrikrishna Khare2016-06-174-19/+64
| | | | | | | | | | | | | | | vmxnet3 driver supports transmit data ring viz. a set of fixed size buffers used by the driver to copy packet headers. Small packets that fit these buffers are copied into these buffers entirely. Currently this buffer size of fixed at 128 bytes. This patch extends transmit data ring implementation to allow variable length transmit data ring buffers. The length of the buffer is read from the emulation during initialization.

* vmxnet3: introduce generalized command interface to configure the deviceShrikrishna Khare2016-06-171-1/+21
| | | | | | | | | | | | | | | | | | | | Shared memory is used to exchange information between the vmxnet3 driver and the emulation. In order to request emulation to perform a task, the driver first populates specific fields in this shared memory and then issues corresponding command by writing to the command register(CMD). The layout of the shared memory was defined by vmxnet3 version 1 and cannot be extended for every new command without breaking backward compatibility. To address this problem, in vmxnet3 version 3, the emulation repurposed a reserved field in the shared memory to represent command information instead. For new commands, the driver first populates the command information field in the shared memory and then issues the command. The emulation interprets the data written to the command information depending on the type of the command. This patch exposes this capability to the driver.

* qeth: omit outbound queue 3 for unicast packets in Priority Queuing on ↵Hans Wippel2016-06-172-4/+17
| | | | | | | | | | | | | | | | | HiperSockets On HiperSockets only outbound queues 0 to 2 are available for unicast packets. Current Priority Queuing implementation in the qeth driver puts outgoing packets in outbound queues 0 to 3. This puts outgoing unicast packets into outbound queue 2 instead of outbound queue 3 when using Priority Queuing on a HiperSocket. Additionally, the default outbound queue cannot be set to outbound queue 3 on HiperSockets.

* qeth: improve set_features error handlingHans Wippel2016-06-171-11/+27
| | | | | | | | | | | | | | | | | | | | | The function set_features is called to configure network device features on the hardware. If errors occur, the network device features should reflect the changed hardware state and the function should return an error in order to notify the user. In case of an error, the current implementation does not necessarily save the changed hardware state in the network device features before an error is returned. This patch improves error handling by saving features, that could be changed, to the network device features before returning an error. If the device is not running, an additional check in fix_features removes features, that require hardware changes, before they are passed to set_features. Thus, the corresponding check was removed in set_features. Signed-off-by: Hans Wippel <hwippel@linux.vnet.ibm.com> Signed-off-by: Ursula Braun <ubraun@linux.vnet.ibm.com> Signed-off-by: David S.

* qeth: add network device features for VLAN devicesHans Wippel2016-06-172-2/+10
| | | | | | | | | | | | | | | | | | | Network device features indicate the capabilities of network devices (e.g., TX checksum offloading and TSO) and their configuration state. Additional network device features (vlan_features) indicate for each network device, which capabilities can be used on VLAN devices, that are configured on the respective base network device. In the current qeth implementation, network device features are only set for the base network devices and not for the VLAN devices. Thus, features like TX checksum offloading cannot be used on VLAN devices. This patch adds network device features to vlan_features, so they can be used by VLAN devices.

| | | | | | | | | | | | | | | | | | | | | | | | | The b53 dsa register access confusingly uses __raw register accessors when both the CPU and the device are big-endian, but it uses little- endian accessors when the same device is used from a little-endian CPU, which makes no sense.
