This is a new device driver for a high performance SR-IOV assisted virtual network for IBM System p and IBM System i systems. The SR-IOV VF will be attached to the VIOS partition and mapped to the Linux client via the hypervisor's VNIC protocol that this driver implements. This driver is able to perform basic tx and rx, new features and improvements will be added as they are being developed and tested.

Igal Liberman says: ==================== Freescale DPAA FMan The Freescale Data Path Acceleration Architecture (DPAA) is a set of hardware components on specific QorIQ multicore processors. This architecture provides the infrastructure to support simplified sharing of networking interfaces and accelerators by multiple CPU cores and the accelerators. One of the DPAA accelerators is the Frame Manager (FMan) which contains a series of hardware blocks: ports, Ethernet MACs, a multi user RAM (MURAM) and Storage Profile (SP). This patch set introduce the FMan drivers. Each driver configures and initializes the corresponding FMan hardware module (described above). The MAC driver offers support for three different types of MACs (eTSEC, TGEC, MEMAC). v9 --> v10: - Addressed feedback from David Miller Remove private CRC implementation - Addressed feedback from Kenneth Klette Jonassen: - Use Kernel PHY API to configure dTSEC TBI - Use Kernel PHY API to configure mEMAC PCS This patchset requires device tree update: https://patchwork.ozlabs.org/patch/559501/ - Addressed feedback from Andy Fleming v8 --> v9: No changes v7 --> v8: - Addressed feedback from David Miller - Support for ARM: - Device tree parsing - IO Accessors - Addressed compilation issue on non-PPC targets v6 --> v7: - Addressed compilation issue on non-PPC targets - Removed B4860 rev 1 support v5 --> v6: - Addressed feedback from Scott: - Moved kernel doc to source files - Removed a series of configurable settings - Miscellaneous code updates v4 --> v5: - Addressed feedback from David Miller: - Removed driver layering - Reduce namespace pollution - Reduce code complexity and size v3 --> v4: - Remove device_initcall call in driver registration (redundant) - Remove hot/cold labels - Minor update in FMan Clock read from device-tree - Update fixed-link support - Addressed feedback from Stephen Hemminger - Remove bogus blank line v2 --> v3: - Addressed feedback from Scott: - Remove typedefs - Remove unnecessary memory barriers - Remove unnecessary casting - Remove KConfig options - Remove early_params - Remove Hungarian notation - Remove __packed__ attribute and padding from structures - Remove unlikely attribute (where it's not needed) - Use proper error codes and remove unnecessary prints - Use proper values for sleep routines - Replace complex Macros with functions - Improve device tree processing code - Use symbolic defines - Add time-out in busy-wait loops - Removed exit code (loadable module support will be added later) - Fixed "fixed-link" issue raised by Joakim Tjernlund v1 --> v2: - Addressed feedback from Paul Bolle: - General feedback of FMan Driver layer - Remove Errata defines - Aligned comments to Kernel Doc - Remove Loadable Module support (not yet supported) - Removed not needed KConfig dependencies - Addressed feedback from Scott Wood - Use Kernel ioread/iowrite services - Squash FLIB source and header patches together This submission is based on the prior Freescale DPAA FMan V3,RFC submission.

For unprivileged functions operations can be authorised by an admin function. Extra steps are introduced to the MCDI protocol in this situation - the initial response from the MCDI tells us that the operation has been deferred, and we must retry when told. We then receive an event telling us to retry. Note that this provides only the functionality for the unprivileged functions, not the handling of the administrative side.

Hannes points out that when we generate tcp reset for timewait sockets we pretend we found no socket and pass NULL sk to tcp_vX_send_reset(). Make it cope with inet tw sockets and then provide tw sk.
