Newer firmware will return the ring group resource when we call hwrm_func_qcaps(). To be compatible with older firmware, use the number of tx rings as the number of ring groups if the older firmware returns 0. When determining how many rx rings we can support, take the ring group resource in account as well in _bnxt_get_max_rings(). Divide and assign the ring groups to VFs. Signed-off-by:

We need to keep track of all resources, such as rx rings, tx rings, cmpl rings, rss contexts, stats contexts, vnics, after we have divided them for the VFs. Otherwise, subsequent ring changes on the PF may not work correctly. We adjust all max resources in struct bnxt_pf_info after they have been assigned to the VFs. There is no need to keep the separate max_pf_tx_rings and max_pf_rx_rings. When SR-IOV is disabled, we call bnxt_hwrm_func_qcaps() to restore the max resources for the PF. Signed-off-by:

1. Use local variable pf for repeated access to this pointer. 2. The 2nd argument num_vfs was unnecessarily declared as pointer to int. This function doesn't change num_vfs so change the argument to int. Signed-off-by:

The hardware resources required to enable NTUPLE varies depending on how many rx channels are configured. We need to make sure we have the resources before we enable NTUPLE. Add bnxt_rfs_capable() to do the checking. In addition, we need to do the same checking in ndo_fix_features(). As the rx channels are changed using ethtool -L, we call netdev_update_features() to make the necessary adjustment for NTUPLE. Calling netdev_update_features() in netif_running() state but before calling bnxt_open_nic() would be a problem. To make this work, bnxt_set_features() has to be modified to test for BNXT_STATE_OPEN for the true hardware state instead of checking netif_running(). Signed-off-by:

During remove_one, the driver should issue hwrm_func_drv_unrgtr command to inform firmware that this function has been unloaded. This is to let firmware keep track of driver present/absent state when driver is gracefully unloaded. A keep alive timer is needed later to keep track of driver state during abnormal shutdown.

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. Signed-off-by:

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.
