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. This flag is useful in later patches while setting MAC address specially in the PCI-passthrough case. Signed-off-by: NShradha Shah <sshah@solarflare.com> Signed-off-by: NDavid S.

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.

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.

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.

When an MCDI command times out (whether or not we find it completed when we poll), call efx_mcdi_abandon(), which tells all subsequent MCDI calls to fail-fast, and queues up an FLR. Because an FLR doesn't lead to receiving any reboot even from the MC (unlike most other types of reset), we have to call efx_ef10_reset_mc_allocations. In efx_start_all(), if a reset (of any kind) is pending, we bail out. Without this, attempts to reconfigure (e.g. change mtu) can cause driver/mc state inconsistency if the first MCDI call triggers an FLR. For similar reasons, on EF10, in efx_reset_down(method=RESET_TYPE_MCDI_TIMEOUT), set the number of active queues to zero before calling efx_stop_all(). And, on farch, in efx_reset_up(method=RESET_TYPE_MCDI_TIMEOUT), set active_queues and flushes pending & outstanding to zero. efx_mcdi_mode_{poll,event}() should not take us out of fail-fast mode. Instead, this is done by efx_mcdi_reset() after the FLR completes. The new FLR reset_type RESET_TYPE_MCDI_TIMEOUT doesn't really fit into the hierarchy of reset 'scopes' whereby efx_reset() decides some resets subsume others. Thus, it uses separate logic. Also, fixed up some inconsistency around RESET_TYPE_MC_BIST, which was in the wrong place in that hierarchy. Signed-off-by: NShradha Shah <sshah@solarflare.com> Signed-off-by: NDavid S.

When using the "separate_tx_channels=1" module parameter, the TX queues are initially numbered starting from the first TX-only channel number (after all the RX-only channels). efx_set_channels() renumbers the queues so that they are indexed from zero. On EF10, the TX queues need to be relabelled in this way before calling the dimension_resources NIC type operation, otherwise the TX queue PIO buffers can be linked to the wrong VIs when using "separate_tx_channels=1".

The primary function of an EF10 controller will share its clock device with other functions in the same domain (which we call secondary functions). To this end, we need to associate functions on the same controller. We do not control probe order, so allow primary and secondary functions to appear in any order. Maintain global lists of all primary functions and of unassociated secondary functions, and a list of secondary functions on each primary function. Use the VPD serial number to tell whether functions are part of the same controller. VPD will not be readable by virtual functions, so this may need to be revisited later.

efx_flush_all() is a really misleading name - it has nothing to do with e.g. flushing DMA queues.

We don't directly control RX ingress on Siena or any later controllers, and so we cannot prevent packets from entering the RX datapath while the RX queues are not set up. This results in the hardware incrementing RX_NODESC_DROP_CNT, but it's not an error and we should not include it in error stats. When bringing an interface up or down, pull (or wait for) stats and count the number of packets that were dropped while the interface was down. Subtract this from the reported RX dropped count.

To run BISTs the MC goes down in to a special mode where it will only respond to MCDI from the testing PF, and TX, RX and event queues are torn down. Other PFs get a message as it goes down to tell them it's going down.
