Add support for yet another ARM member of the R-Car family, R-Car M2, also known as R8A7791 -- it will share the code and data with previously added R8A7790. Despite the Ether devices in these SoCs are indistinguishable at least from the driver's point of view, we do introduce a new platform device ID "r8a7791-ether" unlike the wildcard ID used for R8A7778/9 SoCs, due to newly established policy for the Renesas SoCs.

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates This series contains updates to i40e, igb, ixgbe and ixgbevf. Shannon provides a couple of i40e patches, first restricts the ethtool diag test messages by using netif_info() macro to when the hardware bit is enabled in the message level netdev message mask. Second provides a fix for when there is an out-of-range descriptor request. Kamil provides a fix for i40e by updating the loopback enum types and add information about the current loopback mode to data returned from get_link_info(). Jesse provides a fix for i40e define name that was being mis-used. I40E_ITR_NONE was being used as an ITRN register index by accident because it was easily associated with the i40e Rx ITR and friends defines, when it should be associated with the DYN_CTL register sets. Jacob provides an update for ixgbevf Kconfig description since the VF driver supports more than just the 82599 device. Don and Alex provide a cleanup patch for ixgbe to make it where head, tail, next to clean and next to use are all reset in a single function for both Tx and Rx path. Before, the code for this was spread out over several areas which made it difficult to track what the values were for each of the values. Carolyn provides two igb patches to add a media switching feature for i354 PHY's and new Media Auto Sense for 82580 devices only. Aaron Sierra provides a fix for igb to resolve an issue with the 64-bit PCI addresses being truncated because the return values of pci_resource_start() and pci_resouce_end() were being cast to unsigned long. Guenter Roeck provides two igb patches, first simplifies the code by attaching the hwmon sysfs attributes to hwmon device instead of the PCI device. Second fixes the temperature sensor attribute index by setting it to 1 instead of 0 (per hwmon ABI). ==================== Signed-off-by:

I've realized that I need to call ethtool command to get Ethernet working after booting. Ex call: ethtool -s eth0 autoneg on It was fixing Ethernet even if auto-negotiation was already on. Adding calls to phy_start and phy_stop look like a real solution. Signed-off-by:

Simplify the code. Attach hwmon sysfs attributes to hwmon device instead of pci device. Avoid race conditions caused by attributes being created after registration and provide mandatory 'name' attribute by using new hwmon API. Other cleanup: Instead of allocating memory for hwmon attributes, move attributes and all other hwmon related data into struct hwmon_buff and allocate the entire structure using devm_kzalloc. Check return value from calls to igb_add_hwmon_attr() one by one instead of logically combining them all together. Signed-off-by:

This patch adds support for the hardware feature Media Auto Sense. This feature requires a custom EEPROM image provided by our customer support team. The feature allows hardware designed with dual PHY's, fiber and copper to be used with either media without additional EEPROM changes. Fiber is preferred and driver will swap and configure for fiber media if sensed by the device at any time. Device will swap back to copper if it is the only media detected. Signed-off-by:

This patch adds a new feature which is supported in some PHY's on some i354 devices. This feature is Auto Media Detect and allows which ever media is detected first by the PHY to be the media used and configured by the device. This is a media swapping feature that is wholly contained in the Marvell PHY. Signed-off-by:

Commit f4ec9e95 "mlx4_core: Change bitmap allocator to work in round-robin fashion" introduced round-robin allocation (via bitmap) for all resources which allocate via a bitmap. Round robin allocation is desirable for mcgs, counters, pd's, UARs, and xrcds. These are simply numbers, with no involvement of ICM memory mapping. Round robin is required for QPs, since we had a problem with immediate reuse of a 24-bit QP number (commit f4ec9e95). However, for other resources which use the bitmap allocator and involve mapping ICM memory -- MPTs, CQs, SRQs -- round-robin is not desirable. What happens in these cases is the following: ICM memory is allocated and mapped in chunks of 256K. Since the resource allocation index goes up monotonically, the allocator will eventually require mapping a new chunk. Now, chunks are also unmapped when their reference count goes back to zero. Thus, if a single app is running and starts/exits frequently we will have the following situation: When the app starts, a new chunk must be allocated and mapped. When the app exits, the chunk reference count goes back to zero, and the chunk is unmapped and freed. Therefore, the app must pay the cost of allocation and mapping of ICM memory each time it runs (although the price is paid only when allocating the initial entry in the new chunk). For apps which allocate MPTs/SRQs/CQs and which operate as described above, this presented a performance problem. We therefore roll back the round-robin allocator modification for MPTs, CQs, SRQs.

The current implementation of IPV6_FLOWINFO only gives a result if pktoptions is available (thanks to the ip6_datagram_recv_ctl function). It gives inconsistent results to user space, sometimes there is a result for getsockopt(IPV6_FLOWINFO), sometimes not. This patch add rcv_flowinfo to store it, and return it to the userspace in the same way than other pkt_options. Signed-off-by:

We were already registering MDIO bus, but we were not connecting bgmac to the PHY. Add proper call and implement adjust link function to switch MAC into requested state. At the same time it's possible to drop our internal PHY management. This is a "standard" PHY, so the "Generic PHY" driver works perfectly fine with this. Don't duplicate the code. Finally make use of phy_ethtool_[gs]set functions instead implementing them from scratch. This change was successfully tested on BCM5357. I was able to autonegotiate 1000Mb/s full duplex, as well as force any of the 10/100/1000 half/full modes. Signed-off-by:

If CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS is set, several is_<foo>_ether_addr functions can be slightly improved by using u32 dereferences. I believe all current uses of is_zero_ether_addr and is_broadcast_ether_addr are u16 aligned, so always use u16 references to improve those functions performance. Document the u16 alignment requirements. Signed-off-by:

Jiri Pirko says: ==================== neigh: respect default parms values This is a long standing regression. But since the patchset is bigger and the regression happened in 2007, I'm proposing this to net-next instead. Basically the problem is that if user wants to use /etc/sysctl.conf to specify default values of neigh related params, he is not able to do that. The reason is that the default values are copied to dev instance right after netdev is registered. And that is way to early. The original behaviour for ipv4 was that this happened after first address was assigned to device. For ipv6 this was apparently from the very beginning. So this patchset basically reverts the behaviour back to what it was in 2007 for ipv4 and changes the behaviour for ipv6 so they are both the same. ==================== Signed-off-by: -

Make the behaviour similar to ipv4. This will allow user to set sysctl default neigh param values and these values will be respected even by devices registered before (that ones what do not have address set yet). Signed-off-by:

Jiri Pirko authored
Previously inet devices were only constructed when addresses are added. Therefore the default neigh parms values they get are the ones at the time of these operations. Now that we're creating inet devices earlier, this changes the behaviour of default neigh parms values in an incompatible way (see bug #8519). This patch creates a compromise by setting the default values at the same point as before but only for those that have not been explicitly set by the user since the inet device's creation.

Florian Fainelli says: ==================== net: phy: consolidate PHY reset This patchset consolidates the PHY reset through the MII BMCR register by using a central place were this is done. This patchset resumes the work Kyle Moffett started here: https://lkml.org/lkml/2011/10/20/301 Note that at this point, drivers doing funky things after issuing a PHY reset using phy_init_hw() will still suffer from PHY state machine problems, this will be taken care of later on. ==================== Signed-off-by:

The sh_eth driver issues an uncontrolled PHY reset through the MII register BMCR but fails to wait for the reset to complete, and will also implicitely wipe out all possible PHY fixups applied. Use phy_init_hw() which remedies both problems. Signed-off-by:

Instead of open-coding a PHY reset through the MII BMCR register, use phy_init_hw() which does this for us and ensures that PHY device fixups are also applied. We also remove a call to ethernet_phy_reset() which is now unncessary since phy_attach() calls phy_attach_direct() which in turns calls phy_init_hw(). Signed-off-by:

We also remove a call to phy_reset() due to the following sequence of calls in the driver: phy_scan() -> phy_connect() -> phy_connect_direct() -> phy_attach_direct() -> phy_init_hw() and we only have a call to phy_init() after phy_scan().

There are quite a lot of drivers touching a PHY device MII_BMCR register to reset the PHY without taking care of: 1) ensuring that BMCR_RESET is cleared after a given timeout 2) the PHY state machine resuming to the proper state and re-applying potentially changed settings such as auto-negotiation Introduce phy_poll_reset() which will take care of polling the MII_BMCR for the BMCR_RESET bit to be cleared after a given timeout or return a timeout error code. In order to make sure the PHY is in a correct state, phy_init_hw() first issues a software reset through MII_BMCR and then applies any fixups. Signed-off-by:
