Header parsing, ring refill. It puts the incoming data into an rds_incoming struct, which is passed up to rds-core. Signed-off-by:

Specific to IB is a credits-based flow control mechanism, in addition to the expected usage of the IB API to package outgoing data into work requests. Signed-off-by:

Registers as an RDS transport and an IB client, and uses IB CM API to allocate ids, queue pairs, and the rest of that fun stuff. Signed-off-by:

Some transports may support RDMA features. This handles the non-transport-specific parts, like pinning user pages and tracking mapped regions. Signed-off-by:

Upon receiving a datagram from the transport, RDS parses the headers and potentially queues an ACK. Signed-off-by:

This is the code to send an RDS datagram. Signed-off-by:

Parsing of newly-received RDS message headers (including ext. headers) and copy-to/from-user routines. page.c implements a per-cpu page remainder cache, to reduce the number of allocations needed for small datagrams. Signed-off-by:

RDS exposes a few tunable parameters via sysctls. Signed-off-by:

A simple rds transport to handle loopback connections. Signed-off-by:
-
Andy Grover authored
While arguably the fact that the underlying transport needs a connection to convey RDS's datagrame reliably is not important to rds proper, the transports implemented so far (IB and TCP) have both been connection-oriented, and so the connection state machine-related code is in the common rds code. This patch also includes several work items, to handle connecting, sending, receiving, and shutdown. Signed-off-by:

RDS currently generates a lot of stats that are accessible via the rds-info utility. This code implements the support for this. Signed-off-by:

Andy Grover authored
RDS supports multiple transports. While this initial submission only supports Infiniband transport, this abstraction allows others to be added. We're working on an iWARP transport, and also see UDP over DCB as another possibility. This code handles transport registration. Signed-off-by:

RDS handles per-socket congestion by updating peers with a complete congestion map (8KB). This code keeps track of these maps for itself and ones received from peers. Signed-off-by:

The remaining uses of tg3_nvram_read_swab() either intended to read the data from NVRAM exactly as tg3_nvram_read_be32() did or hide deeper interpretations of the data. For the former case, a direct replacement of tg3_nvram_read_swab() with tg3_nvram_read_be32() is in order. For the latter case, we remove tg3_nvram_read_swab() and document what the code is really doing. Signed-off-by:

Any software requesting NVRAM data as it exists on NVRAM is necessarily requesting that the results be returned as a bytestream. A bytestream data read in from the device can also be thought to be in big endian format. Therefore, all the LE notations in the driver are mislabeled. This patch converts all LE notations to BE notations, carefully evaluating the surrounding code in the process. Signed-off-by:

Matt Carlson authored
This patch removes the blind byteswap of NVRAM data as it is read in. To preserve the logic at the call sites, this patch also inverts every call to tg3_nvram_read() and tg3_nvram_read_swab(). The call swap gets confusing within tg3_nvram_read_le() (LE is a misnomer), but the reader should be able to convince himself / herself that the resulting behavior is still unchanged. Signed-off-by:

tg3_vlan_rx_register() touches the hardware if netif_running() returns false. This patch fixes the problem. Signed-off-by:

The ethtool interface has acquired some new enumerations since the tg3 driver's tg3_set_settings() error checking code was written. The error checking code is no longer complete. This patch rewrites the error checking so that it is future-proofed. Signed-off-by:

The hardware's MTU is configured so that it will accept packets whose VLAN tag is left inline. This means that the hardware will also accept other packets larger than the desired MTU size. This patch checks for and discards packets that are larger than the requested MTU but are not VLAN tagged frames. Signed-off-by:

Commit 6833c043 introduced the phy auto-powerdown capability. While the APD feature only works for 5761 and 5784 asic revisions, the (harmless portion of the) code was applied to all 5705 and newer devices. However, the 5906 phy departs from the usual design. This commit was interfering with the 5906's ability to negotiate link against some switches. This patch corrects the problem. Signed-off-by:
