netback is the host side counterpart to the frontend driver in
drivers/net/xen-netfront.c. The PV protocol is also implemented by
frontend drivers in other OSes too, such as the BSDs and even Windows.
The patch is based on the driver from the xen.git pvops kernel tree but
has been put through the checkpatch.pl wringer plus several manual
cleanup passes and review iterations. The driver has been moved from
drivers/xen/netback to drivers/net/xen-netback.
One major change from xen.git is that the guest transmit path (i.e. what
looks like receive to netback) has been significantly reworked to remove
the dependency on the out of tree PageForeign page flag (a core kernel
patch which enables a per page destructor callback on the final
put_page). This page flag was used in order to implement a grant map
based transmit path (where guest pages are mapped directly into SKB
frags). Instead this version of netback uses grant copy operations into
regular memory belonging to the backend domain. Reinstating the grant
map functionality is something which I would like to revisit in the
future.
Note that this driver depends on 2e820f58f7 "xen/irq: implement
bind_interdomain_evtchn_to_irqhandler for backend drivers" which is in
linux next via the "xen-two" tree and is intended for the 2.6.39 merge
window:
git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git stable/backends
this branch has only that single commit since 2.6.38-rc2 and is safe for
cross merging into the net branch.

- Remove the dependency of cxgb4 and cxgb4vf on INET. cxgb3 really
depends on INET, keep it but add it directly to the driver's Kconfig
entry.
- Make the iSCSI drivers cxgb3i and cxgb4i available in the SCSI menu
without requiring any options in the net driver menu to be enabled
first. Add needed selects so the iSCSI drivers can build their
corresponding net drivers.
- Remove CHELSIO_T*_DEPENDS.

Moreover stop listing all i.MX platforms featuring a FEC, and use
the platform's config symbol that selects registration of a fec device
instead. This might make it easier to add new platforms.

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.

This patch is to add mx28 dual fec support. Here are some key notes
for mx28 fec controller.
- The mx28 fec controller naming ENET-MAC is a different IP from FEC
used on other i.mx variants. But they are basically compatible
on software interface, so it's possible to share the same driver.
- ENET-MAC design on mx28 made an improper assumption that it runs
on a big-endian system. As the result, driver has to swap every
frame going to and coming from the controller.
- The external phys can only be configured by fec0, which means fec1
can not work independently and both phys need to be configured by
mii_bus attached on fec0.
- ENET-MAC reset will get mac address registers reset too.
- ENET-MAC MII/RMII mode and 10M/100M speed are configured
differently FEC.
- ETHER_EN bit must be set to get ENET-MAC interrupt work.

The binary file of the firmware is moved to linux-firmware repository.
The firmwares are rtl_nic/rtl8168d-1.fw and rtl_nic/rtl8168d-2.fw.
The driver goes along if the firmware couldn't be found. However, it
is suggested to be done with the suitable firmware.
Some wrong PHY parameters are directly corrected in the driver.
Simple firmware checking added per Ben Hutchings suggestion.

This change adds the first network driver for the tile architecture,
supporting the on-chip XGBE and GBE shims.
The infrastructure is present for the TILE-Gx networking drivers (another
three source files in the new directory) but for now the the actual
tilegx sources are waiting on releasing hardware to initial customers.
Note that arch/tile/include/hv/* are "upstream" headers from the
Tilera hypervisor and will probably benefit less from LKML review.
