Add dedicated transmit function and transmit completion handler for XDP. The XDP transmit logic and completion logic are different than regular TX ring. The TX buffer is recycled back to the RX ring when it completes. v3: Improved the buffer recyling scheme for XDP_TX. v2: Add trace_xdp_exception(). Add dma_sync.

Add logic for an extra set of TX rings for XDP. If enabled, this set of TX rings equals the number of RX rings and shares the same IRQ as the RX ring set.

To support XDP_TX, we need to add a set of dedicated TX rings, each associated with the NAPI of an RX ring. To assign XDP rings and regular rings in a flexible way, we add a bp->tx_ring_map[] array to do the remapping. The netdev txq index is stored in the new field txq_index so that we can retrieve the netdev txq when handling TX completions. In this patch, before we introduce XDP_TX, the mapping is 1:1. v2: Fixed a bug in bnxt_tx_int(). Signed-off-by: NMichael Chan <michael.chan@broadcom.com> Signed-off-by: NDavid S.

Currently, bnxt_setup_tc() and bnxt_set_channels() have similar and duplicated code to check and reserve rx and tx rings. Add a new function bnxt_reserve_rings() to centralize the logic. This will make it easier to add XDP_TX support which requires allocating a new set of TX rings. Also, the tx ring checking logic in bnxt_setup_msix() can be removed. The rings have been reserved before hand. Signed-off-by: NMichael Chan <michael.chan@broadcom.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Minor refactoring of bnxt_rx_skb() so that it can easily be replaced by a new function that handles packets in a single page. Also, use a function pointer bp->rx_skb_func() to switch to a new function when we add the new mode in the next patch. Add a new field data_ptr that points to the packet data in the bnxt_sw_rx_bd structure. The original data field is changed to void pointer so that it can either hold the kmalloc'ed data or a page pointer. The last parameter of bnxt_rx_skb() which was the length parameter is changed to include the payload offset of the packet in the upper 16 bit. The offset is needed to support the rx page mode and is not used in this existing function. v3: Added a new data_ptr parameter to bp->rx_skb_func(). The caller has the option to modify the starting address of the packet. This will be needed when XDP with headroom support is added. v2: Changed the name of the last parameter to offset_and_len to make the code more clear.

The current code assumes that we will always have at least 2 rx rings, 1 will be used as an aggregation ring for TPA and jumbo page placements. However, it is possible, especially on a VF, that there is only 1 rx ring available. In this scenario, the current code will fail to initialize. To handle it, we need to properly set up only 1 ring without aggregation. Set a new flag BNXT_FLAG_NO_AGG_RINGS for this condition and add logic to set up the chip to place RX data linearly into a single buffer per packet.

In order to properly support TX rate limiting in SRIOV VF functions or NPAR functions, firmware needs better control over tx ring allocations. The new scheme requires the driver to reserve the number of tx rings and to query to see if the requested number of tx rings is reserved. The driver will use the new scheme when the firmware interface spec is 1.6.1 or newer. Signed-off-by: NMichael Chan <michael.chan@broadcom.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

The existing hardware RFS mode uses one hardware RSS context block per ring just to calculate the RSS hash. This is very wasteful and prevents VF functions from using it. The new hardware mode shares the same hardware RSS context for RSS placement and RFS steering. This allows VFs to enable RFS.

Since the network driver and RDMA driver operate on the same PCI function, we need to create an interface to allow the RDMA driver to share resources with the network driver. 1. Create a new bnxt_en_dev struct which will be returned by bnxt_ulp_probe() upon success. After that, all calls from the RDMA driver to bnxt_en will pass a pointer to this struct. 2. This struct contains additional function pointers to register, request msix, send fw messages, register for async events. 3. If the RDMA driver wants to enable RDMA on the function, it needs to call the function pointer bnxt_register_device(). A ulp_ops structure is passed for RCU protected upcalls from bnxt_en to the RDMA driver. 4. The RDMA driver can call firmware APIs using the bnxt_send_fw_msg() function pointer. 5. 1 stats context is reserved when the RDMA driver registers. MSIX and completion rings are reserved when the RDMA driver calls bnxt_request_msix() function pointer. 6. When the RDMA driver calls bnxt_unregister_device(), all RDMA resources will be cleaned up. v2: Fixed 2 uninitialized variable warnings.

All available remaining completion rings not used by the PF should be made available for the VFs so that there are enough rings in the VF to support RDMA.

Now that MSIX is enabled in bnxt_init_one(), resources may be allocated by the RDMA driver before the network device is opened.

To better support the new RDMA driver, we need to move pci_enable_msix() from bnxt_open() to bnxt_init_one(). This way, MSIX vectors are available to the RDMA driver whether the network device is up or down. Part of the existing bnxt_setup_int_mode() function is now refactored into a new bnxt_init_int_mode(). bnxt_init_int_mode() is called during bnxt_init_one() to enable MSIX. The remaining logic in bnxt_setup_int_mode() to map the IRQs to the completion rings is called during bnxt_open(). v2: Fixed compile warning when CONFIG_BNXT_SRIOV is not set.
