VF learns of the current link state via its bulletin board, which might reflect either the physical link state or some user-configured logical state. Whenever the physical link changes or whnever such a configuration is explicitly made by user the PF driver would update the bulletin that the VF reads. But if neither has happened - i.e., PF still hasn't got a physical link up and no additional configuration was done the VF wouldn't have a valid link information available. Simply reflect the physical link state whenever the VF is initialized. The user could then affect it however he wants. Signed-off-by:

qed needs to be informed of the removal of the qede interface prior to its actual removal, as qede has some registered callbacks that might get called async to the removal flow. Signed-off-by:

Need to make sure the slowpath workqueue and the qede lock are ready for the registration of the netdevice, as once registered there's no guarantee those wouldn't be used. Signed-off-by:

Pavel Belous says: ==================== net: ethernet: aquantia: improvements and fixes The following patchset contains improvements and fixes for aQuantia AQtion ethernet driver from net-next tree. Most fixes are based on the comments from Lino Sanfilippo. Sanity testing was performed on real HW. No regression found. v1->v2: 1)Removed buffers copying. 2)Fixed dma error handling. v2->v3: 1)Fixes for aq_ndev_change_mtu: -Use core MTU checking for min_mtu. -Removed extra new_mtu assigment. 2)Reverse XMAS tree in aq_ring_rx_fill. v3->v4: 1)Use ndev->reg_state instead "is_ndev_registered" flag. ==================== Signed-off-by: -

rxd_wb->pkt_len is the total length of the packet. If we received a large packet (with length > AQ_CFG_RX_FRAME_MAX) then we will get multiple buffers. We need to fix the length of the last buffer. Signed-off-by:

netdev_register should be called when everything is initialized. Also we should use net_device->reg_state field instead own "is_ndev_registered" flag to avoid any race. Signed-off-by:

1)Removed unnecessary comparsion "old_mtu == new_mtu". This check is not needed. Function aq_ndev_change_mtu wont be called if mtu has not changed. 2)Removed extra assignment ndev->mtu = new_mtu; This assignment already done inside __dev_set_mtu(). 3)Use core MTU checking for min_mtu.

The ethtool api {get|set}_settings is deprecated. We move this driver to new api {get|set}_link_ksettings. As I don't have the hardware, I'd be very pleased if someone may test this patch. Signed-off-by:Philippe Reynes <tremyfr@gmail.com> Signed-off-by:

Jakub Kicinski says: ==================== nfp: expose more firmware and hw debug info This series is mostly a result of flash firmware team requesting access to some of the information and data necessary for debugging firmware problems. Patch 1 adds a missing error message. Patch 2 prints manufacturing info to logs in case PCI VPD capability is not programmed correctly. Patches 3 and 4 allow reporting NSP ABI version in ethtool -i. Patch 5 allows dumping flash application logs. Patches 6 and 7 provides a way of application firmwares to declare limited SR-IOV support. v2: put some of the code in patch 7 in #ifdef CONFIG_PCI_SRIOV (Yuval). ==================== Signed-off-by: -
Jakub Kicinski authored
Some application firmware projects may choose to limit the number of VFs available below what is specified in PCI capability to be able to reuse the PCIe interface resources. There may also be projects which use cases don't require SR-IOV support at all and therefore don't want to spend time implementing/testing it. Check nfd_vf_cfg_max_vfs firmware symbol to see if application firmware is reporting how many VFs it supports. This mechanism is an opt-in, if symbol is not present we will only look at the PCI capability values. Signed-off-by:

When acquiring NSP communication resource fails user is left with "probe failed with error -2" PCI code message but no info on what caused the problem. Some development boards may not have NSP FW in the flash image. Help users with a more verbouse message. While at it move the whole NSP init to a separate function to keep .probe() callback nice and simple. Signed-off-by:

Since mlx4 NIC are used on PowerPC with 64K pages, we need to adapt MLX4_EN_ALLOC_PREFER_ORDER definition. Otherwise, a fragment sitting in an out of order TCP queue can hold 0.5 Mbytes and it is a serious OOM risk. Fixes: 51151a16 ("mlx4: allow order-0 memory allocations in RX path") Signed-off-by:

Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2017-02-18 This series contains updates to i40e and i40evf only. Alan fixes a bug in which the driver is unable to exit overflow promiscuous mode after having added "too many" mac filters. Ractored the '%*ph' printk format specifier to instead use the print_hex_dump(). Josh adds enabling multicast magic packet wakeup by adding calls to the mac_address_write admin q function during power down to update the PRTPM_SAH/SAL registers with the MC_MAG_EN bit. Jake remove a duplicate call i40e_update_link_info(), since it does not need to call it twice. Fixes and issue where we calculating the wrong switch id on big endian platforms. Avoided sparse warning, by doing a typecast to ensure the value is of the type expected by csum_replace_by_diff(). Mitch fixes a memory leak by freeing resources during i40e_remove(). Cleans up some code confusion by adding a proper code comment. Carolyn fixes a bug introduced with the addition of the per queue ITR feature support in ethtool. Cleans up a duplicate device id from the PCI table. Harshitha fixes a bug which causes the 'Link Detected' field in ethtool to report the correct link status. Benjamin Poirier from SuSE applies a fix ec13ee80 ("virtio_net: invoke softirqs after __napi_schedule") to i40e driver as well. ==================== Signed-off-by:

Resizing currently drops consumer lock. This can cause entries to be reordered, which isn't good in itself. More importantly, consumer can detect a false ring empty condition and block forever. Further, nesting of consumer within producer lock is problematic for tun, since it produces entries in a BH, which causes a lock order reversal: CPU0 CPU1 ---- ---- consume: lock(&(&r->consumer_lock)->rlock); resize: local_irq_disable(); lock(&(&r->producer_lock)->rlock); lock(&(&r->consumer_lock)->rlock); <Interrupt> produce: lock(&(&r->producer_lock)->rlock); To fix, nest producer lock within consumer lock during resize, and keep consumer lock during the whole swap operation.
