| * sh_eth: do not reset PHY needlesslySergei Shtylyov2013-12-191-5/+0
| | | | | | | | | | | | | | | | | | | | | | There's no need anymore to call phy_init_hw() to reset/resume the PHY from the driver, as the call chain in phylib already has reached it, and so reset/resumed the PHY (even resuming it twice). This duplicate reset is not only needless, it e.g. clears the PHY's interrupt enables just setup by phylib and so prevents the expected IRQs from the PHY.

Support in ndo_get_phys_port_id added by Hadar. 2. Change the driver to use by default CQE/EQE size of 64 bytes done by Eyal. This doubles the packet-rate of the NIC. 3. Configure the XPS queue mapping on driver load - added by Ido. 4. Fixes for some small bugs done by Jenny and Matan Patchset was applied and tested against commit: "2372175 lib: hash: follow-up fixups for arch hash" Changes from V1: - Removed Patch 10 "net/mlx4_en: Fix Supported/Advertised link mode reported by ethtool". This patch is needed to be rewritten from scratch and I wouldn't like it to block the rest of the patches in this set. Also, fix to Kconfig suggested by Ben will be sent in next patchset. Changes from V0: - Found some issues in "Reuse memory in RX flow" patch from V0. Removing this patch from the patchset till analyzed and fixed. - Fix some coding style issues in patch 6 "Configure the XPS queue mapping on driver load" - Changed patch 9 "Add NAPI support for transmit side" to use NAPI_POLL_WEIGHT instead of MLX4_EN_TX_BUDGET ==================== Signed-off-by: David S.

This will work for VFs and PFs. The driver uses a new device capability - phys_port_id, The PF driver reads the port phys_port_id from Firmware and stores it.

Ensure exclusive access into state/policy link list for different name space with one global lock is not right in terms of semantics aspect at first place, as they are indeed mutually independent with each other, but also more seriously causes scalability problem. One practical scenario is on a Open Network Stack, more than hundreds of lxc tenants acts as routers within one host, a global xfrm_state/policy_lock becomes the bottleneck. But onces those locks are decoupled in a per-namespace fashion, locks contend is just with in specific name space scope, without causing additional SPD/SAD access delay for other name space.

| * | can: c_can: Speed up rx_poll functionMarkus Pargmann2013-12-171-10/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch speeds up the rx_poll function by reducing the number of register reads. Replace the 32bit register read by a 16bit register read. Currently the 32bit register read is implemented by using 2 16bit reads. This is inefficient as we only use the lower 16bit in rx_poll. The for loop reads the pending interrupts in every iteration. This leads up to 16 reads of pending interrupts. The patch introduces a new outer loop to read the pending interrupts as long as 'quota' is above 0. This reduces the total number of reads. The third change is to replace the for-loop by a ffs loop. Tested on AM335x. I removed all 'static' and 'inline' from c_can.c to see the timings for all functions. I used the function tracer with trace_stats. 125kbit: Function Hit Time Avg s^2 -------- --- ---- --- --- c_can_do_rx_poll 63960 10168178 us 158.977 us 1493056 us With patch: c_can_do_rx_poll 63941 3764057 us 58.867 us 776162.2 us 1Mbit: Function Hit Time Avg s^2 -------- --- ---- --- --- c_can_do_rx_poll 69489 30049498 us 432.435 us 9271851 us With patch: c_can_do_rx_poll 207109 24322185 us 117.436 us 171469047 us Signed-off-by: Markus Pargmann <mpa@pengutronix.de> Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de>
* | | xen-netback: add gso_segs calculationPaul Durrant2013-12-191-4/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | netback already has code which parses IPv4 and v6 headers to set up checksum offsets and these are always applied to GSO packets being sent from frontends. It's therefore suboptimal that GSOs are being marked SKB_GSO_DODGY to defer the gso_segs calculation when netback already has all necessary information to hand to do the calculation. This patch adds that calculation.

* | | net-qdisc-hhf: Heavy-Hitter Filter (HHF) qdiscTerry Lam2013-12-194-0/+781
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch implements the first size-based qdisc that attempts to differentiate between small flows and heavy-hitters. The goal is to catch the heavy-hitters and move them to a separate queue with less priority so that bulk traffic does not affect the latency of critical traffic. Currently "less priority" means less weight (2:1 in particular) in a Weighted Deficit Round Robin (WDRR) scheduler. In essence, this patch addresses the "delay-bloat" problem due to bloated buffers. In some systems, large queues may be necessary for obtaining CPU efficiency, or due to the presence of unresponsive traffic like UDP, or just a large number of connections with each having a small amount of outstanding traffic. In these circumstances, HHF aims to reduce the HoL blocking for latency sensitive traffic, while not impacting the queues built up by bulk traffic. HHF can also be used in conjunction with other AQM mechanisms such as CoDel. To capture heavy-hitters, we implement the "multi-stage filter" design in the following paper: C. Estan and G. Varghese, "New Directions in Traffic Measurement and Accounting", in ACM SIGCOMM, 2002. Some configurable qdisc settings through 'tc': - hhf_reset_timeout: period to reset counter values in the multi-stage filter (default 40ms) - hhf_admit_bytes: threshold to classify heavy-hitters (default 128KB) - hhf_evict_timeout: threshold to evict idle heavy-hitters (default 1s) - hhf_non_hh_weight: Weighted Deficit Round Robin (WDRR) weight for non-heavy-hitters (default 2) - hh_flows_limit: max number of heavy-hitter flow entries (default 2048) Note that the ratio between hhf_admit_bytes and hhf_reset_timeout reflects the bandwidth of heavy-hitters that we attempt to capture (25Mbps with the above default settings). The false negative rate (heavy-hitter flows getting away unclassified) is zero by the design of the multi-stage filter algorithm. With 100 heavy-hitter flows, using four hashes and 4000 counters yields a false positive rate (non-heavy-hitters mistakenly classified as heavy-hitters) of less than 1e-4.
