Jiri Pirko says: ==================== This patchset is based on patch by Narendra_K@Dell.com Once device which can change phys port id during its lifetime adopts this, NETDEV_CHANGEPHYSPORTID event will be added and driver will call call_netdevice_notifiers(NETDEV_NETDEV_CHANGEPHYSPORTID, dev) to propagate the change to userspace. v1->v2: as suggested by Ben, handle -EOPNOTSUPP in rtnl code (wrapped up ndo call) v2->v3: adjusted patch 1 commit message v3->v4: used "%phN" for sysfs printf as suggested by DaveM added igb/igbvf implementation as requested by Or Gerlitz v4->v5: used prandom_u32 to generate id in igb_probe removed duplicate code in ibgvf_probe pushed dev_err string into one line in igbvf_refresh_ppid v5->v6: use uuid_le_gen for generating 16-byte phys port id for igb/igbvf as suggested by BenH 1) Why do we need this, and why do existing facilities fail to provide a way to accomplish this? Currenty there's very hard to tell if two netdevs are using the same physical port. For sr-iov this can be get by sysfs. For other mechanisms, like NPAR there's very hard to do it (one must learn it from NIC BIOS). But even for sr-iov there's no way to say if two netdevs are using the same phys port when these are passed through to virtual guests. This patchset provides the generic way of letting this information know to userspace. This info can be used by apps like NetworkManager, teamd, Wicked, ovs daemon, etc, to do smarter bonding decisions. 2) Why is the physical port ID defined as a 32 byte opaque cookie? What formats and layouts need to be accomodated, and which influenced the design of the ID? For user to distinguish if two netdevs are using the same port, he only needs to compare their phys port ids. Nothing else is needed. This id has no structure for security reasons. VF should not know anything about PF. 3) Are IDs globally unique? Why or why not? If IDs should be globally unique, but only in certain cases, what exactly are those cases. Most of the time only uniqueness needed is in scope of single machine. There might be case when the id should be unique between couple of machines in virtualization environment. Given that for example for igb/igbvf 16B uuid is used, there is no problem for this case as well. But each driver can implement this differently focusing the hw capabilities and needs. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

This patch adds a ndo for getting physical port of the device. Driver which is aware of being virtual function of some physical port should implement this ndo. This is applicable not only for IOV, but for other solutions (NPAR, multichannel) as well. Basically if there is possible to have multiple netdevs on the single hw port.

Use the "swap descriptor" feature of the hardware to properly swap the descriptors when running in big endian mode. Since the swapping occurs on 64 bits words, we also need to provide a separate structure layout for the DMA descriptors between little endian and big endian mode, like is done in the mv643xx_eth driver.

The macros used for the various fields of the RX and TX descriptions are currently declared next to those fields within the structure definitions of the RX and TX descriptors. However, in order to support big endian, we'll have to use the "swap descriptors" features of the hardware, which swaps every byte within each 64 bits word of the descriptors. This requires a separate definition of the RX and TX descriptor structures for little and big endian, as is done in the mv643xx_eth. Those macros can therefore no longer be defined inside those structures. Signed-off-by: NThomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Previously, when the interface was brought down, the driver would set the power state to D3hot. In D3hot, we don't have access to the NVRAM. This patch removes the call to set the power state to PCI_D3hot in close. A following patch will implement the shutdown handler to properly set the D3hot state when the system is going down. Doing the above means that the TG3_PHYFLG_IS_LOW_POWER should not be checked to validate access to the NVRAM.

During probe, the driver is incorrectly switching the power to Vaux on the 5717 and later devices. At this point, we are in D0 state and drawing maximum power. We also definitely have Vmain available. It doesn't make sense to switch to Vaux since it has a lesser maximum power draw and we might go over the limit. On a new system, we observe that not all ports are recognized in some of the slots with this call in place.

This commit adds new firmware command and new firmware event. The firmware raises the MLX4_EVENT_TYPE_OP_REQUIRED event in order to signal the driver it needs to perform an administrative operation throughout the MLX4_CMD_GET_OP_REQ command. At the moment the supported operation is adding/removing multicast entries which are used by the firmware for handling NCSI traffic in B0 steering mode. Also, had to swap the order of mlx4_init_mcg_table() and mlx4_init_eq_table() to make sure that driver will get events only after resources are initialized to handle it.

HW: CQE error with index 0xFFFF - the BF WQE's control segment is STAMPED, so the BF index is 0xFFFF. Error: Invalid Opcode. As a result QP enters the error state and no traffic can be sent.

Jeff Kirsher says: ==================== This series contains updates to e100 and e1000e. The e100 patch from Andy simply updates the netif_printk() to use %*ph to dump small buffers. The changes to e1000e include a fix from Dean Nelson to resolve a issue where a pci_clear_master() was accidentally dropped during a conflict resolution. Wei Young provides 2 patches, one removes an assignment of the default ring size because it was a duplicate. The second changes the packet split receive structure to use PS_PAGE_BUFFERS macro for the length so that problems won't occur when the length is changed. The remaining patches for e1000e are from Bruce Allan, where he provides a number of fixes and updates for I218. In addition, a fix for 82583 which can disappear off the PCIe bus, to resolve this, disable ASPM L1. Bruce also provides a fix to a previous commit (commit e60b22c5 e1000e: fix accessing to suspended device) so that devices are only taken out of runtime power management for those ethtool operations that must access device registers. ==================== Signed-off-by: NDavid S.

Tx hang is an unintended consequence of another workaround that is in the EEPROM for an issue with the firmware at 10Mbps when K1 (a power mode of the MAC-PHY interconnect) is enabled. The issue is resolved by setting appropriate Tx re-transmission timeouts in the PHY and associated K1 entry times in the MAC to allow enough transmissions to occur without triggering a Tx hang. A similar change is needed when linked at 10Mbps to improve latency.
