| * [PATCH] S2io: Large Receive Offload (LRO) feature(v2) for Neterion (s2io) ↵Ravinandan Arakali2006-01-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 10GbE Xframe PCI-X and PCI-E NICs Hi, Below is a patch for the Large Receive Offload feature. Please review and let us know your comments. LRO algorithm was described in an OLS 2005 presentation, located at ftp.s2io.com user: linuxdocs password: HALdocs The same ftp site has Programming Manual for Xframe-I ASIC. LRO feature is supported on Neterion Xframe-I, Xframe-II and Xframe-Express 10GbE NICs. Brief description: The Large Receive Offload(LRO) feature is a stateless offload that is complementary to TSO feature but on the receive path. The idea is to combine and collapse(upto 64K maximum) in the driver, in-sequence TCP packets belonging to the same session. It is mainly designed to improve 1500 mtu receive performance, since Jumbo frame performance is already close to 10GbE line rate. Some performance numbers are attached below. Implementation details: 1. Handle packet chains from multiple sessions(current default MAX_LRO_SESSSIONS=32). 2. Examine each packet for eligiblity to aggregate. A packet is considered eligible if it meets all the below criteria. a. It is a TCP/IP packet and L2 type is not LLC or SNAP. b. The packet has no checksum errors(L3 and L4). c. There are no IP options. The only TCP option supported is timestamps. d. Search and locate the LRO object corresponding to this socket and ensure packet is in TCP sequence. e. It's not a special packet(SYN, FIN, RST, URG, PSH etc. flags are not set). f. TCP payload is non-zero(It's not a pure ACK). g. It's not an IP-fragmented packet. 3. If a packet is found eligible, the LRO object is updated with information such as next sequence number expected, current length of aggregated packet and so on. If not eligible or max packets reached, update IP and TCP headers of first packet in the chain and pass it up to stack. 4. The frag_list in skb structure is used to chain packets into one large packet. Kernel changes required: None Performance results: Main focus of the initial testing was on 1500 mtu receiver, since this is a bottleneck not covered by the existing stateless offloads. There are couple disclaimers about the performance results below: 1. Your mileage will vary!!!! We initially concentrated on couple pci-x 2.0 platforms that are powerful enough to push 10 GbE NIC and do not have bottlenecks other than cpu%; testing on other platforms is still in progress. On some lower end systems we are seeing lower gains. 2. Current LRO implementation is still (for the most part) software based, and therefore performance potential of the feature is far from being realized. Full hw implementation of LRO is expected in the next version of Xframe ASIC. Performance delta(with MTU=1500) going from LRO disabled to enabled: IBM 2-way Xeon (x366) : 3.5 to 7.1 Gbps 2-way Opteron : 4.5 to 6.1 Gbps Signed-off-by: Ravinandan Arakali <ravinandan.arakali@neterion.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These messages end up polluting logs when things like NetworkManager or wpa_supplicant are controlling the driver. They aren't really that useful, and no other drivers output messages like this when the user fiddles with encryption keys. Users can use iwconfig and other wireless-tools methods to determine and change the current transmit key if they wish to do so manually. Therefore, remove the messages.

This patch simply goes back to the way things were. We expect some complaints due to order 3 allocations failing to come back due to this change.

When booting an opposite byte sex kernel (e.g. an LE kernel from BE RedBoot) the current MTD driver fails to handle the partition table and therefore is unable to generate the correct partition map for the flash. So far as I am aware this problem is ARM specific, because only ARM supports software change of the CPU (memory system) byte sex, however the partition table parsing is in generic MTD code. The patch below has been tested on NSLU2 (an IXP4XX based system) with a patch, 10-ixp4xx-copy-from.patch (submitted to linux-arm-kernel - it's ARM specific) required to make the maps/ixp4xx.c driver work with an LE kernel. Builds of the patched system are in the 'unstable' release of OpenSlug and UcSlugC available from www.nslu2-linux.org. These builds are BE, the archives at www.nslu2-linux.org and www.handhelds.org (see monotone.vanille.de) can be built LE (currently DISTRO targets nslu-ltu.conf for LE thumb uclibc (32 bit kernel) and nslu2-lau.conf, nslu2-lag.conf for LE arm uclibc/glibc) and this patch has been tested extensively will both BE and LE systems on the NSLU2 (including swapping between BE and LE by reflashing from both RedBoot and Linux). The patch recognises that the FIS directory (the partition table) is byte-reversed by examining the partition table size, which is known to be one erase block (this is an assumption made elsewhere in redboot.c). If the size matches the erase block after byte swapping the value then byte-reversal is assumed, if not no further action is taken. The patched code is fail safe; should redboot.c be changed to support a partition table with a modified size field the test will fail and the partition table will be assumed to have the host byte sex. If byte-reversal is detected the patch byte swaps the remainder of the 32 bit fields in the copy of the table; this copy is then used to set up the MTD partition map.

Micheal Studer supplied the PID for the USB-Y9 device. I examined the INF file in microHAM's Windows driver package for the USB-KW, USB-YS, USB-IC, USB-DB9 and USB-RS232 devices.
