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.

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.

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: NGao Feng <fgao@ikuai8.com> Reviewed-by: NPhilip Prindeville <philipp@redfish-solutions.com> Signed-off-by: NDavid S.

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.

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.

Userspace programs generally need to know the name of the ppp devices they create. Both ioctl and rtnl interfaces use the ppp<suffix> sheme to name them. But although the suffix used by the ioctl interface can be known by userspace (it's the PPP unit identifier returned by the PPPIOCGUNIT ioctl), the one used by the rtnl is only known by the kernel. This patch brings more consistency between ioctl and rtnl based ppp devices by generating device names using the PPP unit identifer as suffix in both cases. This way, userspace can always infer the name of the devices they create. Signed-off-by: NGuillaume Nault <g.nault@alphalink.fr> Signed-off-by: NDavid S. Miller <davem@davemloft.net>
