2014-06-01net: filter: add test for loading SKF_AD_OFF limitsDaniel Borkmann1-0/+22
This check tests that overloading BPF_LD | BPF_ABS with an always invalid BPF extension, that is SKF_AD_MAX, fails to make sure classic BPF behaviour is correct in filter checker. Also, we add a test for loading at packet offset SKF_AD_OFF-1 which should pass the filter, but later on fail during runtime.

2014-06-01net: ks8851: Don't use regulator_get_optional()Stephen Boyd1-28/+22
We shouldn't be using regulator_get_optional() here. These regulators are always present as part of the physical design and there isn't any way to use an internal regulator or change the source of the reference voltage via software. Given that the only users of this driver in the kernel are DT based, this change should be transparent to them even if they don't specify any supplies because the regulator framework will insert dummy supplies as needed.

2014-06-01net/mlx4_en: Use affinity hintYuval Atias6-4/+50
The “affinity hint” mechanism is used by the user space daemon, irqbalancer, to indicate a preferred CPU mask for irqs. Irqbalancer can use this hint to balance the irqs between the cpus indicated by the mask. We wish the HCA to preferentially map the IRQs it uses to numa cores close to it. To accomplish this, we use cpumask_set_cpu_local_first(), that sets the affinity hint according the following policy: First it maps IRQs to “close” numa cores. If these are exhausted, the remaining IRQs are mapped to “far” numa cores. Signed-off-by: Yuval Atias <yuvala@mellanox.com> Signed-off-by: Amir Vadai <amirv@mellanox.com> Signed-off-by: David S.

This function sets the n'th cpu - local cpu's first. For example: in a 16 cores server with even cpu's local, will get the following values: cpumask_set_cpu_local_first(0, numa, cpumask) => cpu 0 is set cpumask_set_cpu_local_first(1, numa, cpumask) => cpu 2 is set ... cpumask_set_cpu_local_first(7, numa, cpumask) => cpu 14 is set cpumask_set_cpu_local_first(8, numa, cpumask) => cpu 1 is set cpumask_set_cpu_local_first(9, numa, cpumask) => cpu 3 is set ... cpumask_set_cpu_local_first(15, numa, cpumask) => cpu 15 is set Curently this function will be used by multi queue networking devices to calculate the irq affinity mask, such that as many local cpu's as possible will be utilized to handle the mq device irq's.

2014-05-30be2net: re-factor MCCQ error status handling codeKalesh AP3-45/+57
This patch improves MCCQ error status handling in the following ways: a) A MCC cmd completion returns a base-status and an addl-status. So far, the routine be_mcc_compl_process() returned only the "status" value. Now, embedd both statuses in the return value and let the caller routine access the value of interest using base_status() and addl_status() macros. b) Rename variables accordingly (base/addl) to avoid confusion while error checking. b) Some of the errors returned by FW are harmless and so an error msg is not logged for such errors. Capture this logic in a separate routine to make the code more readable.

2014-05-29i40e: Tx/Rx rings declarationAkeem G Abodunrin2-8/+7
This patch changes the declaration of Tx/Rx rings inside several loops. It eliminates declaring the same rings every time for the duration of the loop, instead declaring them once before the loop.

2014-05-29i40evf: tweak Tx rate params and de-magic-ifyMitch Williams1-2/+5
In order for the VF to achieve its programmed Tx rate, we need to set the max credits value to 4. While we're at it, get rid of some magic numbers.

2014-05-29i40evf: don't round Tx rate down to 0Mitch Williams1-0/+5
Because the hardware configures VF Tx rates in increments of 50 Mbps, values smaller than that would be rounded down to 0, which was interpreted as no limit at all. Rather than do this, we round up to 50 Mbps and notify the user.

2014-05-29i40e: enable descriptor prefetch for VFsMitch Williams1-0/+1
As recommended by the hardware guys, enable descriptor prefetch for rings belonging to VFs. This matches a change already made for ring belonging to the PF.
