The network driver uses two virtqueues: one for input packets and one
for output packets. This has nice locking properties (ie. we don't do
any for recv vs send).
TODO:
1) Big packets.
2) Multi-client devices (maybe separate driver?).
3) Resolve freeing of old xmit skbs (Christian Borntraeger)

Based on BenH's earlier work, this is a new version of the EMAC driver
for the built-in ethernet found on PowerPC 4xx embedded CPUs. The
same ASIC is also found in the Axon bridge chip. This new version is
designed to work in the arch/powerpc tree, using the device tree to
probe the device, rather than the old and ugly arch/ppc OCP layer.
This driver is designed to sit alongside the old driver (that lies in
drivers/net/ibm_emac and this one in drivers/net/ibm_newemac). The
old driver is left in place to support arch/ppc until arch/ppc itself
reaches its final demise (not too long now, with luck).
This driver still has a number of things that could do with cleaning
up, but I think they can be fixed up after merging. Specifically:
- Should be adjusted to properly use the dma mapping API.
Axon needs this.
- Probe logic needs reworking, in conjuction with the general
probing code for of_platform devices. The dependencies here between
EMAC, MAL, ZMII etc. make this complicated. At present, it usually
works, because we initialize and register the sub-drivers before the
EMAC driver itself, and (being in driver code) runs after the devices
themselves have been instantiated from the device tree.

This patch adds support for the Intel 82598 PCI-Express 10GbE
chipset. Devices will be available on the market soon.
This version of the driver is largely the same as the last release:
* Driver uses a single RX and single TX queue, each using 1 MSI-X
irq vector.
* Driver runs in NAPI mode only
* Driver is largely multiqueue-ready (TM)
Changes since 20070803:
* removed wrappers for hardware functions
* incorporated e1000e-style HW api reorganization code
* sparse/checkpatch cleanups, namespace cleanups
* driver prints out extra debugging information at load time
identifying adapter board number, mac, phy types
* removed ixgbe_api.c, ixgbe_api.h, ixgbe_osdep.h
* driver update to 1.1.18
* removed ixgbe.txt which contained no useful info anymore

Veth stands for Virtual ETHernet. It is a simple tunnel driver
that works at the link layer and looks like a pair of ethernet
devices interconnected with each other.
Mainly it allows to communicate between network namespaces but
it can be used as is as well.
The newlink callback is organized that way to make it easy to
create the peer device in the separate namespace when we have
them in kernel.
This implementation uses another interface - the RTM_NRELINK

HBAs, the driver is split into two modules:
mlx4_core: Handles low-level things like device initialization and
processing firmware commands. Also controls resource allocation
so that the InfiniBand, ethernet and FC functions can share a
device without stepping on each other.
mlx4_ib: Handles InfiniBand-specific things; plugs into the

migrate ucc_geth to use the common phylib code.
There are several side effects from doing this:
o deprecate 'interface' property specification present
in some old device tree source files in
favour of a split 'max-speed' and 'interface-type'
description to appropriately match definitions
in include/linux/phy.h. Note that 'interface' property
is still honoured if max-speed or interface-type
are not present (backward compatible).
o compile-time CONFIG_UGETH_HAS_GIGA is eliminated
in favour of probe time speed derivation logic.
o adjust_link streamlined to only operate on maccfg2
and upsmr.r10m, instead of reapplying static initial
values related to the interface-type.
o Addition of UEC MDIO of_platform driver requires
platform code add 'mdio' type to id list
prior to calling of_platform_bus_probe (separate patch).
o ucc_struct_init introduced to reduce ucc_geth_startup

This is a driver for the Silan SC92031/Rsltek 8139D NIC chip.
This chip is found on at least one counterfeit Encore ENL832-TX-RENT NIC
[1], which came with a mini-CD with the 2.4 driver. A slightly older
version of the driver was found at [2]. The main difference between them
is that the newer one has a small bugfix in the RX path, a lot of
gratuitous renaming of functions, all the printable strings changed to show
as a "Rsltek 8139D" [sic], and a PCI ID of 8139 instead of 2031. The
driver on this patch is a rewrite of the vendor drivers (based mostly on
the older one).
Changes from the previous patch sent to netdev:
- Use MMIO instead of PIO
- Changed TX bounce buffers allocation
- Use skb_copy_and_csum_dev
- Several small bug fixes
- Tested for more than just a few minutes each time
[1] See http://www.encore-usa.com/faq.php under ENL832-TX-RENT for more

Add tsi108/9 on chip Ethernet controller driver support.
The driver code collects the feedback of previous posting form the mailing
list and gives the update.
MPC7448HPC2 platform in arch/powerpc uses tsi108 bridge.
The following is a brief description of the Ethernet controller:
The Tsi108/9 Ethernet Controller connects Switch Fabric to two independent
Gigabit Ethernet ports,E0 and E1. It uses a single Management interface to
manage the two physical connection devices (PHYs). Each Ethernet port has
its own statistics monitor that tracks and reports key interface
statistics. Each port supports a 256-entry hash table for address
filtering. In addition, each port is bridged to the Switch Fabric through
a 2-Kbyte transmit FIFO and a 4-Kbyte Receive FIFO.
Each Ethernet port also has a pair of internal Ethernet DMA channels to
support the transmit and receive data flows. The Ethernet DMA channels use
descriptors set up in memory, the memory map of the device, and access via
the Switch Fabric. The Ethernet Controller’s DMA arbiter handles
arbitration for the Switch Fabric. The Controller also has a register bus
interface for register accesses and status monitor control.
The PMD (Physical Media Device) interface operates in MII, GMII, or TBI
modes. The MII mode is used for connecting with 10 or 100 Mbit/s PMDs.
The GMII and TBI modes are used to connect with Gigabit PMDs. Internal
data flows to and from the Ethernet Controller through the Switch Fabric.
Each
Ethernet port uses its transmit and receive DMA channels to manage data
flows through buffer descriptors that are predefined by the system (the
descriptors can exist anywhere in the system memory map). These
descriptors are data structures that point to buffers filled with data
ready to transmit over Ethernet, or they point to empty buffers ready to
receive data from Ethernet.

etherh and a handful of other odd drivers use different macros when building
8390.c. Since we generate a single 8390.o and then link with it, in any
config with both oddball and normal 8390-based driver we will end up with
breakage in at least one of them. Solution: take most of 8390.c into
lib8390.c and have 8390.c, etherh.c and the rest of oddballs #include it.
Helper macros are taken from 8390.h to whoever includes lib8390.c. That
way odd drivers get separate instances of compiled 8390 stuff and stop
stepping on each other's toes. 8390.h gets cleaned up - we don't have
the cascade of ifdefs in there and are left with the stuff that can be
used by any 8390-based driver. Current problems are exactly because of
that cascade - we attempt to choose the set of helpers by looking at config
and that, of course, doesn't work well when we have several sets needed
by various drivers in our config.

This is a complementary network driver for our ISP4XXX parts.
There is a concurrent effort underway to get the iSCSI driver (qla4xxx)
integrated upstream as well.
I have been through several iterations with the linux-netdev list and have had
much response from Stephen Hemminger.
- Built and tested using kernel 2.6.17-rc4.
- The chip supports two ethernet and two iSCSI functions.
- The functions ql_sem_lock, ql_sem_spinlock, ql_sem_unlock, and
ql_wait_for_drvr_lock are used to protect resources that are shared across
the network and iSCSI functions. This protection is mostly during chip
initialization and resets, but also include link management.
- The PHY/MII are not exported through ethtool due to the fact that the
iSCSI function will control the common link at least 50% of the time.
This driver has been through several iterations on the netdev list and we feel
this driver is ready for inclusion in the upstream kernel.
It has been built and tested on x86 and PPC64 platforms.
