The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option is used to configure any non-standard kernel with a much larger scope than only small devices. This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes references to the option throughout the kernel. A new CONFIG_EMBEDDED option is added that automatically selects CONFIG_EXPERT when enabled and can be used in the future to isolate options that should only be considered for embedded systems (RISC architectures, SLOB, etc). Calling the option "EXPERT" more accurately represents its intention: only expert users who understand the impact of the configuration changes they are making should enable it.

As a first step in moving from LRO to GRO, revert commit af40da89 ("IPoIB: add LRO support"). Also eliminate the ethtool set_flags callback which isn't needed anymore. Finally, we need to include <linux/sched.h> directly to get the declaration of restart_syscall() (which used to be included implicitly through <linux/inet_lro.h>).

The help text for INFINIBAND_IPOIB_DEBUG refers to "ipoib_debugfs," which no longer exists. Correct this to talk about the files under debugfs that are really created. Signed-off-by: NRoland Dreier <rolandd@cisco.com>

Add "ipoib_use_lro" module parameter to enable LRO and an "ipoib_lro_max_aggr" module parameter to set the max number of packets to be aggregated. Make LRO controllable and LRO statistics accessible through ethtool.

The following patch adds experimental support for IPoIB connected mode, as defined by the draft from the IETF ipoib working group. The idea is to increase performance by increasing the MTU from the maximum of 2K (theoretically 4K) supported by IPoIB on top of UD. With this code, I'm able to get 800MByte/sec or more with netperf without options on a Mellanox 4x back-to-back DDR system. Some notes on code: 1. SRQ is used for scalability to large cluster sizes 2. Only RC connections are used (UC does not support SRQ now) 3. Retry count is set to 0 since spec draft warns against retries 4. Each connection is used for data transfers in only 1 direction, so each connection is either active(TX) or passive (RX). 2 sides that want to communicate create 2 connections. 5. Each active (TX) connection has a separate CQ for send completions - this keeps the code simple without CQ resize and other tricks 6. To detect stale passive side connections (where the remote side is down), we keep an LRU list of passive connections (updated once per second per connection) and destroy a connection after it has been unused for several seconds. The LRU rule makes it possible to avoid scanning connections that have recently been active. Signed-off-by: NMichael S. Tsirkin <mst@mellanox.co.il> Signed-off-by: NRoland Dreier <rolandd@cisco.com>

Don't allow CONFIG_INFINIBAND_IPOIB_DEBUG to be disabled unless CONFIG_EMBEDDED is selected. We want users (and especially distros) to have this turned on unless they really need to save space, because by the time we want debugging output, it's usually too late to rebuild a kernel. The debugging output can be controlled at runtime via the debug_level module parameter in sysfs. Signed-off-by: NRoland Dreier <rolandd@cisco.com>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
