2017-02-14sfc: MSI-X is the only interrupt mode for EF10 VFsAndrew Rybchenko1-1/+4
Add min_interrupt_mode specification per NIC type. It is a bit confusing because of "highest interrupt mode is less capable". Signed-off-by: Edward Cree <ecree@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-02-09sfc: configure UDP tunnel offload portsJon Cooper1-0/+19
Implement ndo_udp_tunnel_{add,del} to update the NIC's list of VXLAN and GENEVE UDP ports. Also reset the port list to empty on driver load and on driver unload, with appropriate flag set on the unload case. These port numbers are used for RX inner checksum offload, and in future will also be used for TX inner checksum offload and encapsulated TSO.

2017-02-09sfc: process RX event inner checksum flagsJon Cooper1-7/+12
Add support for RX checksum offload of encapsulated packets. This essentially just means paying attention to the inner checksum flags in the RX event, and if *either* checksum flag indicates a fail then don't tell the kernel that checksum offload was successful. Also, count these checksum errors and export the counts to ethtool -S. Test the most common "good" case of RX events with a single bitmask instead of a series of ifs. Move the more specific error checking in to a separate function for clarity, and don't use unlikely() there since we know at least one of the bits is bad.

2017-01-16sfc: allow PIO more oftenEdward Cree1-0/+9
If an option descriptor has been sent on a queue but not followed by a packet, there will have been no completion event, so the read and write counts won't match and we'll think we can't do PIO. This combines with the fact that we have two TX queues (for en/disable checksum offload), and that both must be empty for PIO to happen. This patch adds a separate "packet_write_count" that tracks the most recent write_count we expect to see a completion event for; this excludes option descriptors but _includes_ PIO descriptors (even though they look like option descriptors). This is then used, rather than write_count, in efx_nic_tx_is_empty(). We only bother to maintain packet_write_count on EF10, since on Siena (a) there are no option descriptors and it always equals write_count, and (b) there's no PIO, so we don't need it anyway.

2017-01-04sfc: don't report RX hash keys to ethtool when RSS wasn't enabledEdward Cree1-0/+2
If we failed to set up RSS on EF10 (e.g. because firmware declared RX_RSS_LIMITED), ethtool --show-nfc $dev rx-flow-hash ... should report no fields, rather than confusingly reporting what fields we _would_ be hashing on if RSS was working.

2016-12-03sfc: remove EFX_BUG_ON_PARANOID, use EFX_WARN_ON_[ONCE_]PARANOID insteadEdward Cree1-11/+11
Logically, EFX_BUG_ON_PARANOID can never be correct. For, BUG_ON should only be used if it is not possible to continue without potential harm; and since the non-DEBUG driver will continue regardless (as the BUG_ON is compiled out), clearly the BUG_ON cannot be needed in the DEBUG driver. So, replace every EFX_BUG_ON_PARANOID with either an EFX_WARN_ON_PARANOID or the newly defined EFX_WARN_ON_ONCE_PARANOID. Signed-off-by: Edward Cree <ecree@solarflare.com> Signed-off-by: David S.

2016-11-30sfc: separate out SFC4000 ("Falcon") support into new sfc-falcon driverEdward Cree1-3/+1
Rationale: The differences between Falcon and Siena are in many ways larger than those between Siena and EF10 (despite Siena being nominally "Falcon- architecture"); for instance, Falcon has no MCPU, so there is no MCDI. Removing Falcon support from the sfc driver should simplify the latter, and avoid the possibility of Falcon support being broken by changes to sfc (which are rarely if ever tested on Falcon, it being end-of-lifed hardware). The sfc-falcon driver created in this changeset is essentially a copy of the sfc driver, but with Siena- and EF10-specific code, including MCDI, removed and with the "efx_" identifier prefix changed to "ef4_" (for "EFX 4000- series") to avoid collisions when both drivers are built-in. This changeset removes Falcon from the sfc driver's PCI ID table; then in sfc I've removed obvious Falcon-related code: I removed the Falcon NIC functions, Falcon PHY code, and EFX_REV_FALCON_*, then fixed up everything that referenced them. Also, increment minor version of both drivers (to 4.1). For now, CONFIG_SFC selects CONFIG_SFC_FALCON, so that updating old configs doesn't cause Falcon support to disappear; but that should be undone at some point in the future.

2016-11-18sfc: remove Software TSOEdward Cree1-0/+5
It gives no advantage over GSO now that xmit_more exists. If we find ourselves unable to handle a TSO skb (because our TXQ doesn't have a TSOv2 context and the NIC doesn't support TSOv1), hand it back to GSO. Also do that if the TSO handler fails with EINVAL for any other reason. As Falcon-architecture NICs don't support any firmware-assisted TSO, they no longer advertise TSO feature flags at all.

2016-11-18sfc: Firmware-Assisted TSO version 2Bert Kenward1-2/+45
Add support for FATSOv2 to the driver. FATSOv2 offloads far more of the task of TCP segmentation to the firmware, such that we now just pass a single super-packet to the NIC. This means TSO has a great deal in common with a normal DMA transmit, apart from adding a couple of option descriptors. NIC-specific checks have been moved off the fast path and in to initialisation where possible. This also moves FATSOv1/SWTSO to a new file (tx_tso.c). The end of transmit and some error handling is now outside TSO, since it is common with other code. Signed-off-by: Edward Cree <ecree@solarflare.com> Signed-off-by: David S.

2016-08-12sfc: set interrupt moderation via MCDIBert Kenward1-4/+6
SFN8000-series NICs require a new method of setting interrupt moderation, via MCDI. This is indicated by a workaround flag. This new MCDI command takes an explicit time value rather than a number of ticks. It therefore makes sense to also store the moderation values in terms of time, since that is what the ethtool interface is interested in.

2016-06-15sfc: VLAN filters must only be created if the firmware supports this.Martin Habets1-0/+12
If it is not supported we simply disable the feature. For the feature to work we need firmware filter support for OUTER_VID + LOC_MAC and for OUTER_VID + LOC_MAC_IG. The low-latency firmware can match on OUTER_VID + LOC_MAC but not on OUTER_VID + LOC_MAC_IG. For the capture packet firmware it is the other way around. Only the full-feature variant can match on both combinations. Incorporates a fix by Andrew Rybchenko <Andrew.Rybchenko@oktetlabs.ru> in the net_dev->[hw_]features handling.

2015-11-02sfc: push partner queue for skb->xmit_moreMartin Habets1-0/+2
When the IP stack passes SKBs the sfc driver puts them in 2 different TX queues (called partners), one for checksummed and one for not checksummed. If the SKB has xmit_more set the driver will delay pushing the work to the NIC. When later it does decide to push the buffers this patch ensures it also pushes the partner queue, if that also has any delayed work. Before this fix the work in the partner queue would be left for a long time and cause a netdev watchdog.

2015-10-12sfc: fully reset if MC_REBOOT event received without warm_boot_count incrementDaniel Pieczko1-0/+1
On EF10, MC_CMD_VPORT_RECONFIGURE can cause a CODE_MC_REBOOT event to be sent to a function without incrementing the (adapter-wide) warm_boot_count. In this case, the reboot is not detected by the loop on efx_mcdi_poll_reboot(), so prepare for recovery from an MC reboot anyway. When this codepath is run, the MC has always just rebooted, so this recovery is valid. The loop on efx_mcdi_poll_reboot() is still required for other MC reboot cases, so that actions in response to an MC reboot are performed, such as clearing locally calculated statistics. Siena NICs are unaffected by this change as the above scenario does not apply. Signed-off-by: Shradha Shah <sshah@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-08-28sfc: Allow driver to cope with a lower number of VIs than it needs for RSSShradha Shah1-0/+1
Previously, the driver would refuse to load if it couldn't secure enough VIs from the MC to fulfill its RSS requirements. This was causing probe to fail on later functions in configurations where we'd run out of VIs, such as having many VFs. This change allows the driver to load with fewer VIs, down to a minimum of 2. A warning will be printed saying that RSS requirements were not met, possibly affecting performance. efx->max_tx_channels needs to be set to avoid going down the failure path in efx_probe_nic() immediately in the loop after the probe() NIC-type function. Also, Set rc=ENOSPC when bombing out of efx_probe_nic due to lack of VIs. Signed-off-by: Shradha Shah <sshah@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-07-21sfc: support cascaded multicast filtersDaniel Pieczko1-0/+2
If the workaround to support cascaded multicast filters ("workaround_26807") is enabled, the broadcast filter and individual multicast filters are not inserted when in promiscuous or allmulti mode. There is a race while inserting and removing filters when entering and leaving promiscuous mode. When changing promiscuous state with cascaded multicast filters, the old multicast filters are removed before inserting the new filters to avoid duplicating packets; this can lead to dropped packets until all filters have been inserted. The efx_nic:mc_promisc flag is added to record the presence of a multicast promiscuous filter; this gives a simple way to tell if the promiscuous state is changing.

2015-07-09sfc: Report TX completions to BQL after all TX events in interruptPeter Dunning1-0/+2
The limit for BQL is updated each time we call netdev_tx_completed_queue. Without this patch the BQL limit was updated for every TX event we see. The issue was that this only updated the limit to handle the data we complete in two events as the first event wouldn't show that enough traffic had been processed between them. This was OK when interrupt moderation was off but not when it was on as more data had to be completed in a single interrupt. The patch changes this so that we do report the completion to BQL only when all the TX events in the interrupt have been processed.

2015-05-21sfc: set the MAC address using MC_CMD_VADAPTOR_SET_MACShradha Shah1-1/+2
Add a set_mac_address() NIC-type function for EF10 only, and use this to set the MAC address on the vadaptor. For Siena and earlier, the MAC address continues to be set by MC_CMD_SET_MAC; this is still called on EF10, and including a MAC address in this command has no effect. The sriov_mac_address_changed() NIC-type function is no longer needed on EF10, but it is needed for Siena where it is used to update the peer address of the PF for VFDI. Change this to use the new set_mac_address function pointer. efx_ef10_sriov_mac_address_changed() is no longer called, as VFs will try to change the MAC address on their vadaptor rather than trying to change to the context of the PF to alter the vport. When a VF is running in direct passthrough mode with MAC spoofing enabled, it will be able to change the MAC address on its vadaptor. In this case, there is a link to the PF, so find the correct VF in its ef10_vf array and update the MAC address. ndo_set_mac_address() can be called during driver unload while bonding, and in this case the device has already been stopped, so don't call efx_net_open() to restart it after reconfiguration. efx->port_enabled is set to false in efx_stop_port(), so it is indicator of whether the device needs to be restarted.

2015-05-21sfc: protect filter table against use-after-freeEdward Cree1-1/+4
If MCDI timeouts are encountered during efx_ef10_filter_table_remove(), an FLR will be queued, but efx->filter_state will still be kfree()d. The queued FLR will then call efx_ef10_filter_table_restore(), which will try to use efx->filter_state. This previously caused a panic.
