Sergei Shtylyov says: ==================== Add PHY IRQ support to the 'sh_eth' driver This patchset adds support for passing PHY's IRQ to the 'sh_eth' driver from the platform code and removes now useless code that hinders the PHY IRQ handing by philib. ==================== Signed-off-by: -
Sergei Shtylyov authored
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. Signed-off-by:

Amir Vadai says: ==================== net/mlx4: Mellanox driver update 08-12-2013 This patchset contains: 1. 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: "23721754 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:

To achieve out of the box performance default is to use 64 byte CQE/EQE. In tests that we conduct in our labs, we achieved a performance improvement of twice the message rate. For older VF/libmlx4 support, enable_64b_cqe_eqe must be set to 0 (disabled). Signed-off-by:

Hadar Hen Zion authored
Add the infrastructure needed to support ndo_get_phys_port_id which allows users to identify to which physical port a net-device is connected to by reading a unique port id. 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. The VF driver reads the port phys_port_id from the PF using QUERY_FUNC_CAP command. Signed-off-by:

From Fan Du. 2) Make xfrm migration namespace aware. From Fan Du. 3) Make the xfrm state and policy locks namespace aware. From Fan Du. 4) Remove ancient sleeping when the SA is in acquire state, we now queue packets to the policy instead. This replaces the sleeping code. 5) Remove FLOWI_FLAG_CAN_SLEEP. This was used to notify xfrm about the posibility to sleep. The sleeping code is gone, so remove it. 6) Check user specified spi for IPComp. Thr spi for IPcomp is only 16 bit wide, so check for a valid value. From Fan Du. 7) Export verify_userspi_info to check for valid user supplied spi ranges with pfkey and netlink. From Fan Du. 8) RFC3173 states that if the total size of a compressed payload and the IPComp header is not smaller than the size of the original payload, the IP datagram must be sent in the original non-compressed form. These packets are dropped by the inbound policy check because they are not transformed. Document the need to set 'level use' for IPcomp to receive such packets anyway. From Fan Du. Please pull or let me know if there are problems. ==================== Signed-off-by: -

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. Signed-off-by:

It can be a bit confusing when looking for checksumming flags that the actual comment for this resides elsewhere further below in the header file. Thus, bring the documentation where we define these flags, and slightly improve the doc text to make it a bit more clear/readable. Also, whitespace-align values of the define while at it.

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.
