The code in be_check_ufi_compatibility() checks to see if a UFI file meant for a lower rev of a chip is being flashed on a higher rev, which is disallowed.

When an RXQ is created in be_open(), the driver currently posts only 64 buffers. This sometimes results in packet drops when there is a traffic burst as soon as the interface is enabled.

When the FW runs out of vlan filters it can either return an INSUFFICIENT_RESOURCES error or an INSUFFICIENT_VLANS error. The driver currently checks only for the former error value.

Currently pkts with L3 or L4 errors received on PFs are not dropped by the adapter, but instead sent to the stack. This helps the network stack to better reflect error statistics.

Currently adaptive interrupt moderation is set by calculating and configuring an EQ-delay every second. This is done via a FW-cmd. But, on Skyhawk-R a "re-arm to interrupt" delay can be set while ringing the EQ-DB. This patch uses this facility to calculate and set the interrupt delay every 1ms. This helps moderating interrupts better when the traffic is bursty.

This patch adds support for spoofchk configuration for VFs. When it is enabled, "spoof checking" is done for both MAC-address and VLAN. For each VF, the HW ensures that the source MAC address (or vlan) of every outgoing packet exists in the MAC-list (or vlan-list) configured for RX filtering for that VF. If not, the packet is dropped and an error is reported to the driver in the TX completion; this is reflected in the "tx_spoof_check_err" ethtool counter. This feature is supported in Skyhawk FW version 10.6.31.0 and above.

Shradha Shah says: ==================== sfc: Enabling EF10 Vf's, set up vswitching and bind the SFC driver to the VF's This set of patches makes way for the implementation of EF10 SR-IOV driver starting with some cleanup code. NIC specific SR-IOV functions are moved to their own header and netdev_ops are made generic instead of being NIC specific Next in line comes the patch to enable VF's using sriov_configure. VEB vswitching hierarchy is set up next followed by patches to prepare sfc driver to bind to enabled VF's This is followed by patch to support use of shared RSS contexts which makes VF's use shared RSS contexts in all cases. Patch series ends with a patch to bind the sfc driver to the enabled VF's which creates network interfaces corresponding to the VF's. Coming up soon are the patches to set_vf_mac, set_vf_config, set_vf_vlan, vf_spoofcheck, etc. These patches have been tested with and without CONFIG_SFC_SRIOV. In the case of CONFIG_SFC_SRIOV=y enabling of VF's using sriov_configure is also tested. The enabled VF's bind to the installed sfc driver succesfully to create network interfaces. In the case of CONFIG_SFC_SRIOV=n enabling of VF's using sriov_configure returns the correct error message: "Function not implemented". ==================== Signed-off-by: NDavid S.

Add the device ID of the VF to the PCI device ID table. Added a boolean flag is_vf in efx_nic_type to differentiate between a VF and PF at probe time.

Allow PFs to allocate shared RSS contexts if we exhaust our exclusive RSS contexts. Make VFs use shared RSS contexts in all cases. Spruce up error handling so that the shadow copy of the RSS table is updated after successful update, rather than in all cases, so that we report the actual contents of the RSS table after a failure to set it, rather than what we'd like it to be. Populate context_size parameter when vacuously allocating RSS context of size 1. Signed-off-by: NShradha Shah <sshah@solarflare.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

* Accept EPERM in some simple cases, the following cases are handled: 1) efx_mcdi_read_assertion() Unprivileged PCI functions aren't allowed to GET_ASSERTS. We return success as it's up to the primary PF to deal with asserts. 2) efx_mcdi_mon_probe() in efx_ef10_probe() Unprivileged PCI functions aren't allowed to read sensor info, and worrying about sensor data is the primary PF's job. 3) phy_op->reconfigure() in efx_init_port() and efx_reset_up() Unprivileged functions aren't allowed to MC_CMD_SET_LINK, they just have to accept the settings (including flow-control, which is what efx_init_port() is worried about) they've been given. 4) Fallback to GET_WORKAROUNDS in efx_ef10_probe() Unprivileged PCI functions aren't allowed to set workarounds. So if efx_mcdi_set_workaround() fails EPERM, use efx_mcdi_get_workarounds() to find out if workaround_35388 is enabled. 5) If DRV_ATTACH gets EPERM, try without specifying fw-variant Unprivileged PCI functions have to use a FIRMWARE_ID of 0xffffffff (MC_CMD_FW_DONT_CARE). 6) Don't try to exit_assertion unless one had fired Previously we called efx_mcdi_exit_assertion even if efx_mcdi_read_assertion had received MC_CMD_GET_ASSERTS_FLAGS_NO_FAILS. This is unnecessary, and the resulting MC_CMD_REBOOT, even if the AFTER_ASSERTION flag made it a no-op, would fail EPERM for unprivileged PCI functions. So make efx_mcdi_read_assertion return whether an assert happened, and only call efx_mcdi_exit_assertion if it has. Signed-off-by: NShradha Shah <sshah@solarflare.com> Signed-off-by: NDavid S.

To be able to use MC_CMD_VADAPTOR_SET_MAC, vadaptors must be manually allocated and freed as automatic vadaptors will disappear when their reference_count reaches zero, which must happen before the MAC address is changed. Vadaptors are allocated and freed in the vswitching_probe/remove functions for PFs and VFs, and this means that vadaptors are restored correctly following an MC reboot or other reset when required.

The parent PF creates vports for all its child VFs and adds MAC addresses to these. When the VF driver loads, it can make an MCDI call to get the MAC address that the parent PF assigned it. The parent PF also assigns a mac address to its own vport because implicit creation of a vAdaptor will only work on evb ports with MAC addresses assigned. The vport MAC address needs to be stored in the PF's nic_data struct as it can later be changed on the vadaptor (and its net_dev struct). When removing a vport the original MAC address must be deleted. A new flag is needed in the VF data structure to identify whether a vport has been assigned to the VF. This is to determine whether it needs to be un-assigned before freeing the vport. Also, attempting to un-assign a vport which is not assigned will result in an EALREADY error.

Adds functions to allocate and free vswitches and vports; vadaptors are automatically allocated and freed when TX/RX queues are initialised and finalised. This vswitching structure is only created if the firmware supports it, so a check that full-featured firmware is running is performed first. If the MC resets, the vswitching infrastructure will need to be recreated, so mark the "must_probe_vswitching" flag when an MC reboot is detected. Don't try to create a vswitch if vf-count=0 This allocation of vswitches and vports does not currently support configuring VLAN tags, but that can be added in a future change.

The default port ID of EVB_PORT_ID_ASSIGNED is a "magic" number for the MCFW to select the physical port of the PF. If other vswitches and vports are created on top of the default firmware configuration, the ID of the newly created vport is then required when passed to MCDI commands. Currently, this doesn't happen so the vport_id is never changed, but a subsequent patch will change this behaviour so that other vswitches and vports are created. The vport_id recorded in nic_data is only relevant for PFs. VFs will have their vports created by their parent PF, and in that case the parent PF will record the vport ID of each VF. For a VF, nic_data->vport_id is expected to remain at the default value. Signed-off-by: NShradha Shah <sshah@solarflare.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

The (future) code to add/remove vswitches and vports will be dependent on the firmware variant. To simplify the checking of the firmware variant, record values for rx_dpcpu_fw_id and tx_dpcpu_fw_id in EF10 nic_data. There was only one place where this was previously used: efx_mcdi_print_fwver() in ethtool.c. The MC_CMD_GET_CAPABILITIES can be replaced and the values from nic_data used instead. Note that the printing of "?" if the MC command fails or if the outlength is incorrect no longer apply, because errors are returned in efx_ef10_init_datapath_caps() in both of these cases.

The efx_vf struct contains Siena-specific fields for VFs, so rename to siena_vf.

sfc: Own header for nic-specific sriov functions, single instance of netdev_ops and sriov removed from Falcon code By putting all the efx_{siena,ef10}_sriov_* declarations in {siena,ef10}_sriov.h, ensure they cannot be called from nic-generic code. Also fixes up an instance of this, where mcdi.c was calling efx_siena_sriov_flr. The single instance of netdev_ops should call general high level functions that can then call something adapter specific in efx_nic_type. We should only do adapter specialisation via efx_nic_type. Removal of sriov functionality from the Falcon code means that tests are needed for the presence of some callbacks. Signed-off-by: NShradha Shah <sshah@solarflare.com> Signed-off-by: NDavid S.

Andrew Lunn says: ==================== More Marvell DSA refactring and fixup This patch setup continues the refactoring and cleanup of the Marvell DSA drivers. Patch #1 Centralizes the duplicated parts of port setup and global setup into the shared mv88e6xxx. Patch #2 Centralizes looping over the ports setting them up Patch #3 Uses mnemonics for the remaining register access in the drivers. Patch #4 The 6172 is actually a member of the 6352 family. This moves the probe code into the correct driver. Patch #5 Adds more members of the 6171 family to the 6171 driver. The new devices are untested. Patch #6 The 6185 is a member of the 6131 family. Add it to the probe code of the 6131 driver. Patch #7 and Patch #8 Simply the mutex's in mv88e6xxx.c. The SMI bus is the bottleneck, not the granularity of the mutex's so simply the code down to a single mutex. Patch #8 Fixes a false positive lockdep splat, due to nested uses of MDIO busses. Patch #9 Fixes another false positive lockdep splat with the transmit queue because of stacked Ethernet devices. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>
