* staging: fsl-mc: move mc-cmd.h contents in the public headerLaurentiu Tudor2017-06-291-1/+0Star
| | | | | | | | | mc-cmd.h contains some low level functions used to encode and decode commands to the MC. They are used by the drivers so move them to the public headers and get rid of the mc-cmd.h header.

| | | | | | | | | dpni.c is using byte order macros and error codes but does not explicitly include the required kernel header, so add it.

* staging: fsl-dpaa2/eth: Update number of netdev queuesIoana Radulescu2017-06-131-0/+14
| | | | | | | | | | | | Currently, the netdevice is allocated with a default number of Rx/Tx queues equal to CONFIG_NR_CPUS, meaning the maximum number of cores supported by the current kernel. The actual number of queues is reflected by the DPNI object attribute, so update the netdevice configuration based on that.

* staging: fsl-dpaa2/eth: Refactor MAC address setupIoana Radulescu2017-06-131-17/+29
| | | | | | | | | The driver logic for allocating a MAC address to a net device is complicated enough to deserve a function of its own. While here, cleanup a bit the code comments.

| | | | | | | | | | On the egress path, frame errors are reported using both a FD control field and the frame annotation status. The current code only handles FAS errors. Update to look at both fields when accounting Tx errors.

| | | | | | | | | We only need to know the buffer pool id, so save exactly that in the device's private structure, instead of the entire DPBP attributes struct. Signed-off-by: Ioana Radulescu <ruxandra.radulescu@nxp.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

| | | | | | | | | Remove the dpni_id and buffer_layout fields from device's private structure. They're only used at probe so we don't need to store them for further use. Signed-off-by: Ioana Radulescu <ruxandra.radulescu@nxp.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

| | | | | | | | | | | If the Ethernet driver doesn't find any DPIO devices during probe, it may be either because there's none available or because they haven't been probed yet. Request deferred probing in case it's the latter.

* staging: fsl-dpaa2/eth: Map Tx buffers as bidirectionalIoana Radulescu2017-05-291-7/+7
| | | | | | | | | | | | | WRIOP hardware may need to write to the hardware annotation area of Tx buffers (e.g. frame status bits) and also to the data area (e.g. L4 checksum in frame header). Map these buffers as DMA_BIDIRECTIONAL, otherwise the write transaction through SMMU will not be allowed.

| | | | | | | | | | | | | | | | Introduce the DPAA2 Ethernet driver, which manages Datapath Network Interface (DPNI) objects discovered on the MC bus. In addition to DPNIs, the Ethernet driver uses several other MC objects to build a network interface abstraction: buffer pools (DPBPs), I/O Portals (DPIOs) and concentrators (DPCONs).
