Bert Kenward says: ==================== sfc: SFN8000 support improvements This series improves support for the recently released SFN8000 series of adapters. Specifically, it retrieves interrupt moderation timer settings directly from the adapter and uses those settings. It also uses a new event queue initialisation interface, allowing specification of a performance objective rather than enabling individual flags. ==================== Signed-off-by: -

On SFN8000 series adapters the MC provides a method to get the timer quantum and the maximum timer setting. We revert to the old values if the new call is unavailable. Signed-off-by:

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. Signed-off-by:

Rather than explicitly specifying flags we can now specify a desired performance target to the firmware, ie higher throughput or lower latency. For now we use the default "auto" configuration. Signed-off-by:

This core can be used in all three modes of operation(10/100/1000 Mb/s). The Management Data Input/Output (MDIO) interface is used to configure the Speed of operation. This core can switch dynamically between the three Different speed modes by configuring the conveter register through mdio write.

Ivan Khoronzhuk says: ==================== net: ethernet: ti: cpsw: split driver data and per ndev data In dual_emac mode the driver can handle 2 network devices. Each of them can use its own private data and common data/resources. This patchset splits common driver data/resources and private per net device data. It leads to: - reduce memory usage - increase code readability - allows add a bunch of simplification - create prerequisites to add multi-channel support, when channels are shared between net devices Doesn't have bad impact on performance. v2: https://lkml.org/lkml/2016/8/6/108 Since v2: - removed patch: net: ethernet: ti: cpsw: fix int dbg message - replaced patch: "net: ethernet: ti: cpsw: remove redundant check in napi poll" on "net: ethernet: ti: cpsw: remove intr dbg msg from poll handlers" - removed macro "cpsw_get_slave_ndev" - corrected some commits Since v1: - added several patch improvements - avoided variable reordering in structures - removed static variable for common function - split big patch on several patches: ==================== Signed-off-by:

At poll handler no possibility to figure out which network device is handling packets, as cpdma channels are common for both network devices in dual_emac mode. Currently, the messages are printed only for one device, in fact, there is two. This print msg is incorrect and seems is not very useful, so drop it from poll handler. Reviewed-by:

The PPTP is encapsulated by GRE header with that GRE_VERSION bits must contain one. But current GRE RPS needs the GRE_VERSION must be zero. So RPS does not work for PPTP traffic. In my test environment, there are four MIPS cores, and all traffic are passed through by PPTP. As a result, only one core is 100% busy while other three cores are very idle. After this patch, the usage of four cores are balanced well. Signed-off-by:

Convert the per-device linked list into a hashtable. The primary motivation for this change is that currently, we're not tracking all the qdiscs in hierarchy (e.g. excluding default qdiscs), as the lookup performed over the linked list by qdisc_match_from_root() is rather expensive. The ultimate goal is to get rid of hidden qdiscs completely, which will bring much more determinism in user experience. Reviewed-by:

ic_close_devs() calls kfree() for all devices's ic_device. Since commit 2647cffb ("net: ipconfig: Support using "delayed" DHCP replies") the active device's ic_device is still used however to print the ipconfig summary which results in an oops if the memory is already changed. So delay freeing until after the autoconfig results are reported. Fixes: 2647cffb ("net: ipconfig: Support using "delayed" DHCP replies") Reported-by:

The interface would not function after the system had been woken up after have been suspended (echo mem > /sys/power/state) cycle. The reason for this is that all device registers have been reset to its default values. This patch adds sleep suspend and resume functions that detached the interface at suspend and restore the registers and reattach the interface at resume. Only the registers that are only configured at probe time needs to be explicitly restored by the resume handler. All other registers are reconfigured by either reopening the device in the resume handler (if the device was running when the system was suspended) or when the interface is opened by a user at a later time.
