2017-08-28bnxt_en: Improve tx ring reservation logic.Michael Chan1-2/+3
When the number of TX rings is changed (e.g. ethtool -L, enabling XDP TX rings, etc), the current code tries to reserve the new number of TX rings before closing and re-opening the NIC. If we are unable to reserve the new TX rings, we abort the operation and keep the current TX rings. The problem is that the firmware will disable the current TX rings even when it cannot reserve the new set of TX rings. We fix it as follows: 1. Instead of reserving the new set of TX rings, just ask the firmware to check if the new set of TX rings is available. There is a flag in the firmware message to do that. If not available, abort and the current TX rings will not be disabled. 2. Do the actual TX ring reservation in the path that opens the NIC. We keep the number of TX rings currently successfully reserved. If the number of TX rings is different than the reserved TX rings, we call firmware and reserve again.

2017-07-24bnxt_en: add support for port_attr_get and and get_phys_port_nameSathya Perla1-0/+2
This patch adds support for the switchdev_port_attr_get() and ndo_get_phys_port_name() methods for the PF and the VF-reps. Using this support a user application can deduce that the PF (when in the ESWITCH_SWDEV mode) and it's VF-reps form a switch.

2017-07-24bnxt_en: add vf-rep RX/TX and netdev implementationSathya Perla1-0/+10
This patch introduces the RX/TX and a simple netdev implementation for VF-reps. The VF-reps use the RX/TX rings of the PF. For each VF-rep the PF driver issues a VFR_ALLOC FW cmd that returns "cfa_code" and "cfa_action" values. The FW sets up the filter tables in such a way that VF traffic by default (in absence of other rules) gets punted to the parent PF. The cfa_code value in the RX-compl informs the driver of the source VF. For traffic being transmitted from the VF-rep, the TX BD is tagged with a cfa_action value that informs the HW to punt it to the corresponding VF.

2017-07-24bnxt_en: add support to enable VF-representorsSathya Perla1-0/+32
This patch is a part of a patch-set that introduces support for VF-reps in the bnxt_en driver. The driver registers eswitch mode get/set methods with the devlink interface that allow a user to enable SRIOV switchdev mode. When enabled, the driver registers a VF-rep netdev object for each VF with the stack. This can essentially bring the VFs unders the management perview of the hypervisor and applications such as OVS. The next patch in the series, adds the RX/TX routines and a slim netdev implementation for the VF-reps.

2017-07-11bnxt_en: Fix bug in ethtool -L.Michael Chan1-1/+2
When changing channels from combined to rx/tx or vice versa, the code uses the wrong "sh" parameter to determine if we are reserving rings for shared or non-shared mode. It should be using the ethtool requested "sh" parameter instead of the current "sh" parameter. Fix it by passing the "sh" parameter to bnxt_reserve_rings(). For ethtool, we will pass in the requested "sh" parameter. Fixes: 391be5c27364 ("bnxt_en: Implement new scheme to reserve tx rings.")

.ndo_get_stats64() may not be protected by RTNL and can race with .ndo_stop() or other ethtool operations that can free the statistics memory. Fix it by setting a new flag BNXT_STATE_READ_STATS and then proceeding to read statistics memory only if the state is OPEN. The close path that frees the memory clears the OPEN state and then waits for the BNXT_STATE_READ_STATS to clear before proceeding to free the statistics memory.

2017-02-07bnxt_en: Refactor rx SKB function.Michael Chan1-2/+9
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.

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.

2016-12-07bnxt_en: Add interface to support RDMA driver.Michael Chan1-0/+6
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.
