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.

2019-11-22sfc: suppress MCDI errors from ARFSEdward Cree2-6/+30
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.

2019-11-22sfc: change ARFS expiry mechanismEdward Cree4-32/+45
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>

2019-11-22cxgb4/chcr: update SGL DMA unmap for USORahul Lakkireddy4-115/+52
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.

2019-11-22ice: Only disable VF state when freeing each VF resourcesAkeem G Abodunrin1-4/+8
It is wrong to set PF disable state flag for all VFs when freeing VF resources - Instead, we should set VF disable state flag for each VF with its resources being returned to the device. Right now, all VF opcodes, mailbox communication to clear its resources as well fails - since we already indicate that PF is in disable state, with all VFs not active. In addition, we don't need to notify VF that PF is intending to reset it, if it is already in disabled state.

2019-11-22ice: fix stack leakageJesse Brandeburg1-2/+1
In the case of an invalid virtchannel request the driver would return uninitialized data to the VF from the PF stack which is a bug. Fix by initializing the stack variable earlier in the function before any return paths can be taken.

2019-11-22ice: Don't modify stripping for add/del VLANs on VFBrett Creeley1-8/+31
Currently when adding/deleting vlans in ice_vc_process_vlan_msg() we are calling ice_vsi_manage_vlan_stripping() to enable/disable when adding and deleting a VLAN respectively. This is wrong because adding/deleting VLANs has nothing to do with configuring VLAN stripping. VLAN stripping is configured through the following VIRTCHNL operations: VIRTCHNL_OP_ENABLE_VLAN_STRIPPING VIRTCHNL_OP_DISABLE_VLAN_STRIPPING Unfortunately we can't just remove this because then stripping will never be configured on VF initialization. Fix this by adding a new function that initializes (disables/enables) VLAN stripping for the VF based on the device supported capabilities. This allows us to remove the call to ice_vsi_manage_vlan_stripping() in ice_vc_process_vlan_msg().

2019-11-22ice: Disallow VF VLAN opcodes if VLAN offloads disabledBrett Creeley1-0/+29
Currently if the host disables VLAN offloads on the VF by not setting the VIRTCHNL_VF_OFFLOAD_VLAN capability bit we will still honor VF VLAN configuration messages over VIRTCHNL. These messages (i.e. enable/disable VLAN stripping and VLAN filtering) should be blocked when the feature is not supported. Fix that by adding a helper function to determine if the VF is allowed to do VLAN operations based on the host's VF configuration. Also, mirror the VF communicated capabilities in the host's VF configuration.

2019-11-22ice: Correct capabilities reporting of max TCsBruce Allan1-0/+12
Firmware always returns 8 as the max number of supported TCs. However on devices with more than 4 ports, the maximum number of TCs per port is limited to 4. Check and, if necessary, correct the reporting of capabilities for devices with more than 4 ports.
