The driver currently only assignes 1 RSS context to each VF. This works for the Linux VF driver. But other drivers, such as DPDK, can make use of additional RSS contexts. Modify the code to divide up and assign RSS contexts to VFs just like other resources.

Driver calls HWRM_FUNC_RESET firmware call while resuming the device which clears the context memory backing store. Because of which allocating firmware resources would eventually fail. Fix it by freeing all context memory during suspend and reallocate the memory during resume. Call bnxt_hwrm_queue_qportcfg() in resume path. This firmware call is needed on the 57500 chips so that firmware will set up the proper queue mapping in relation to the context memory.

After driver unregister, firmware is erasing the information that driver supports new resource management. Send FUNC_RESOURCE_QCAPS command to inform the firmware that driver supports new resource management while resuming from hibernation. Otherwise, we fallback to the older resource allocation scheme. Also, move driver register after sending FUNC_RESOURCE_QCAPS command to be consistent with the normal initialization sequence.

Everytime driver registers with firmware, driver is required to register for async event notifications as well. These 2 calls are done using the same firmware command and can be combined. We are also missing the 2nd step to register for async events in the suspend/resume path and this will fix it. Prior to this, we were getting only default notifications. ULP can register for additional async events for the RDMA driver, so we add a parameter to the new function to only do step 2 when it is called from ULP.

In the bnxt_init_one() failure path, if the driver has already called firmware to register the driver, it is not undoing the driver registration.

Disable Bus master during suspend to prevent DMAs after the device goes into D3hot state. The new 57500 devices may continue to DMA from context memory after the system goes into D3hot state.

Rename the mac_link_state() method to mac_pcs_get_state() to make it clear that it should be returning the MACs PCS current state, which is used for inband negotiation rather than just reading back what the MAC has been configured for. Update the documentation to explicitly mention that this is for inband. We drop the return value as well; most of phylink doesn't check the return value and it is not clear what it should do on error - instead arrange for state->link to be false.

When a phydev is created, the speed and duplex are set to zero and -1 respectively, rather than using the predefined SPEED_UNKNOWN and DUPLEX_UNKNOWN constants. There is a window at initialisation time where we may report link down using the 0/-1 values. Tidy this up and use the predefined constants, so debug doesn't complain with: "Unsupported (update phy-core.c)/Unsupported (update phy-core.c)" when the speed and duplex settings are printed.

In high connection count usage, the NIC's filter table may be filled with sufficiently many ARFS filters that further insertions fail. As this does not represent a correctness issue, do not log the resulting MCDI errors. Add a debug-level message under the (by default disabled) rx_status category instead; and take the opportunity to do a little extra expiry work. Since there are now multiple workitems able to call __efx_filter_rfs_expire on a given channel, it is possible for them to race and thus pass quotas which, combined, exceed rfs_filter_count. Thus, don't WARN_ON if we loop all the way around the table with quota left over.

Edward Cree authored
The old rfs_filters_added method for determining the quota could potentially allow the NIC to become filled with old filters, which never get tested for expiry. Instead, explicitly make expiry check work depend on the number of filters installed, and don't count checking slots without filters in as doing work. This guarantees that each filter will be checked for expiry at least once every thirty seconds (assuming the channel to which it belongs is NAPI polling actively) regardless of fill level.

Jeff Kirsher says: ==================== This series contains updates to the ice driver only. Bruce updates the driver to store the number of functions the device has so that it won't have to compute it when setting safe mode capabilities. Adds a check to adjust the reporting of capabilities for devices with more than 4 ports, which differ for devices with less than 4 ports. Brett adds a helper function to determine if the VF is allowed to do VLAN operations based on the host's VF configuration. Also adds a new function that initializes VLAN stripping (enabled/disabled) for the VF based on the device supported capabilities. Adds a check if the vector index is valid with the respect to the number of transmit and receive queues configured when we set coalesce settings for DCB. Adds a check if the promisc_mask contains ICE_PROMISC_VLAN_RX or ICE_PROMISC_VLAN_TX so that VLAN 0 promiscuous rules to be removed. Add a helper macro for a commonly used de-reference of a pointer to &pf->dev->pdev. Jesse fixes an issue where if an invalid virtchnl request from the VF, the driver would return uninitialized data to the VF from the PF stack, so ensure the stack variable is initialized earlier. Add helpers to the virtchnl interface make the reporting of strings consistent and help reduce stack space. Implements VF statistics gathering via the kernel ndo_get_vf_stats(). Akeem ensures we disable the state flag for each VF when its resources are returned to the device. Tony does additional cleanup in the driver to ensure the when we allocate and free memory within the same function, we should not be using devm_* variants; use regular alloc and free functions. Henry implements code to query and set the number of channels on the primary VSI for a PF via ethtool. Jake cleans up needless NULL checks in ice_sched_cleanup_all(). Kevin updates the firmware API version to align with current NVM images. v2: Added "Fixes:" tag to patch 5 commit description and added the use of netif_is_rxfh_configured() in patch 13 to see if RSS has been configured by the user, if so do not overwrite that configuration. ==================== Signed-off-by: Jakub Kicinski <jakub.kicinski@netronome.com>

Rahul Lakkireddy authored
The FW_ETH_TX_EO_WR used for sending UDP Segmentation Offload (USO) requests expects the headers to be part of the descriptor and the payload to be part of the SGL containing the DMA mapped addresses. Hence, the DMA address in the first entry of the SGL can start after the packet headers. Currently, unmap_sgl() tries to unmap from this wrong offset, instead of the originally mapped DMA address. So, use existing unmap_skb() instead, which takes originally saved DMA addresses as input. Update all necessary Tx paths to save the original DMA addresses, so that unmap_skb() can unmap them properly. v2: - No change.
