Add support for TI DaVinci EMAC driver.
TI DaVinci Ethernet Media Access Controller module is based upon
TI CPPI 3.0 DMA engine and supports 10/100 Mbps on all and Gigabit modes on
some TI devices. It supports MII/RMII and has up to 8Kbytes of internal
descriptor memory. This driver has been working on several TI devices including
DM644x, DM646x and DA830 platforms. The specs of this device are available at:

>From now on FW will be downloaded from the binary file using request_firmware.
There will be different files for every supported chip. Currently 57710 (e1) and
57711 (e1h).
File names have the following format: bnx2x-<chip version>-<FW version>.fw.
ihex versions of current FW files are submitted in the next patch.
Each binary file has a header in the following format:
struct bnx2x_fw_file_section {
__be32 len;
__be32 offset;
}
struct bnx2x_fw_file_hdr {
struct bnx2x_fw_file_section init_ops;
struct bnx2x_fw_file_section init_ops_offsets;
struct bnx2x_fw_file_section init_data;
struct bnx2x_fw_file_section tsem_int_table_data;
struct bnx2x_fw_file_section tsem_pram_data;
struct bnx2x_fw_file_section usem_int_table_data;
struct bnx2x_fw_file_section usem_pram_data;
struct bnx2x_fw_file_section csem_int_table_data;
struct bnx2x_fw_file_section csem_pram_data;
struct bnx2x_fw_file_section xsem_int_table_data;
struct bnx2x_fw_file_section xsem_pram_data;
struct bnx2x_fw_file_section fw_version;
}
Each bnx2x_fw_file_section contains the length and the offset of the appropriate
section in the binary file. Values are stored in the big endian format.
Data types of arrays:
init_data __be32
init_ops_offsets __be16
XXsem_pram_data u8
XXsem_int_table_data u8
init_ops struct raw_op {
u8 op;
__be24 offset;
__be32 data;
}
fw_version u8
>From now boundaries of a specific initialization stage are stored in
init_ops_offsets array instead of being defined by separate macroes. The index
in init_ops_offsets is calculated by BLOCK_OPS_IDX macro:
#define BLOCK_OPS_IDX(block, stage, end) \
(2*(((block)*STAGE_IDX_MAX) + (stage)) + (end))
Security:
In addition to sanity check of array boundaries bnx2x will check a FW version.
Additional checks might be added in the future.

This patch adds support for the Xilinx ll_temac 10/100/1000 Ethernet
device. The ll_temac ipcore is typically used on Xilinx Virtex and
Spartan designs attached to either a PowerPC 4xx or Microblaze
processor.
At the present moment, this driver only works with Virtex5 PowerPC
designs because it assumes DCR is used to access the DMA registers.
However, the low level access to DMA registers is abstracted and
it should be easy to adapt for the other implementations.
I'm posting this driver now as an RFC. There are still some things that
need to be tightened up, but it does appear to be stable.
Derived from driver code written by Yoshio Kashiwagi and David H. Lynch Jr.
Tested on Xilinx ML507 eval board with Base System Builder generated
FPGA design.

This adds an igbvf driver to handle virtual functions provided by the
igb driver when SR-IOV has been enabled. A virtual function is a
lightweight pci-e function that supports a single queue and shares
resources with the 82576 physical function contained within the igb
driver.
To spawn virtual functions from the igb driver all that is needed is to
enable CONFIG_PCI_IOV and have an 82576 Ethernet adapter on a system that
supports SR-IOV in the BIOS. The virtual functions will appear after the
interface is loaded.

This patch adds a platform device driver that supports the OpenCores 10/100
Mbps Ethernet MAC.
The driver expects three resources: one IORESOURCE_MEM resource defines the
memory region for the core's memory-mapped registers while a second
IORESOURCE_MEM resource defines the network packet buffer space. The third
resource, of type IORESOURCE_IRQ, associates an interrupt with the driver.

This patch makes cxgb3 invoke the GRO hooks instead of LRO. As
GRO has a compatible external interface to LRO this is a very
straightforward replacement.
I've kept the ioctl controls for per-queue LRO switches. However,
we should not encourage anyone to use these.
Because of that, I've also kept the skb construction code in
cxgb3. Hopefully we can phase out those per-queue switches
and then kill this too.

This patch makes igb invoke the GRO hooks instead of LRO. As
GRO has a compatible external interface to LRO this is a very
straightforward replacement.
Three things of note:
1) I've kept the LRO Kconfig option until we decide to enable
GRO across the board at which point it can also be killed.
2) The poll_controller stuff is broken in igb as it tries to do
the same work as the normal poll routine. Since poll_controller
can be called in the middle of a poll, this can't be good.
I noticed this because poll_controller can invoke the GRO hooks
without flushing held GRO packets.
However, this should be harmless (assuming the poll_controller
bug above doesn't kill you first :) since the next ->poll will
clear the backlog. The only time when we'll have a problem is
if we're already executing the GRO code on the same ring, but
that's no worse than what happens now.
3) I kept the ip_summed check before calling GRO so that we're
on par with previous behaviour.

cxgb3i requires the cxgb3 net driver, so it selects it. However,

option (CONFIG_CHELSIO_T3_DEPENDS) and make both cxgb3 and cxgb3i

This patch adds better IPv6 failover support for bonding devices,
especially when in active-backup mode and there are only IPv6 addresses
configured, as reported by Alex Sidorenko.
- Creates a new file, net/drivers/bonding/bond_ipv6.c, for the
IPv6-specific routines. Both regular bonds and VLANs over bonds
are supported.
- Adds a new tunable, num_unsol_na, to limit the number of unsolicited
IPv6 Neighbor Advertisements that are sent on a failover event.
Default is 1.
- Creates two new IPv6 neighbor discovery functions:
ndisc_build_skb()
ndisc_send_skb()
These were required to support VLANs since we have to be able to
add the VLAN id to the skb since ndisc_send_na() and friends
shouldn't be asked to do this. These two routines are basically
__ndisc_send() split into two pieces, in a slightly different order.
- Updates Documentation/networking/bonding.txt and bumps the rev of bond
support to 3.4.0.
On failover, this new code will generate one packet:
- An unsolicited IPv6 Neighbor Advertisement, which helps the switch
learn that the address has moved to the new slave.
Testing has shown that sending just the NA results in pretty good
behavior when in active-back mode, I saw no lost ping packets for example.
