This patch makes igb driver ioport-free.
This corrects behavior in probe function so as not to request ioport
resources as long as they are not really needed.

We do not want to prolong the situation much longer that e1000
and e1000e support these devices at the same time. As a result,
take out the bandage that was added for the interim period
and remove all the PCI Express device IDs from e1000.

Three basic changes to the comments at the top of each file:
1) remove stale "Maintained by" line...I prefer people look in MAINTAINERS.
2) Drop reference to stale sf.net/tulip website (I didn't see anything
of value there)
3) Point people at bugzilla.kernel.org to submit bugs...will always
get tracked regardless of who the maintainer is.

Currently all but one user (AT91SAM9261EK) of the dm9000
driver passes their IRQ flags through the resources attached
to the platform device. This means we can remove the use
of DEFAULT_TRIGGER as the blackfin machines all seem to
have their triggers set properly.

The DM9000's internal PHY reports a copy of the link status
in the NSR register of the chip. Reading the status when
polling for link status is faster as it eliminates the need
to sleep, but does not print as much information.
Add an platform flag to force this behaviour, and a Kconfig
option to allow it to be forced to the faster method always.

The DM9000_NSR register contains a copy of the internal PHY's
link status which we can use to determine if the link is up
or down. This eliminates the more costly (and sleeping) PHY
read when using the DM9000's own PHY.

The dm9000 driver accepts either 2 or 3 resources to describe the platform
devices. The 2 resources case abuses the ioresource mechanism by passing
ioremap()ed memory through the platform device resources. This patch removes
that case and converts boards that were using it to the 3 resources scheme.

The TPA stands for Transparent Packet Aggregation. When enabled, the FW
aggregate in-order TCP packets according to the 4-tuple match and sends
1 big packet to the driver. This packet is stored on an SGL in which
each SGE is 1 page. The FW also implements a timeout algorithm and it
honors all TCP flag, including the push flag as a trigger to halt
aggregation.
After receiving Ben Hutchings comments, we also added ethtool support,
so now, thanks to Ben's patch, when forwarding is enabled, our
aggregation is turned off using the LRO flags.

To support the new members in the family, the bnx2x structure was

This new initialization code supports the 57711 HW. It also supports
the emulation and FPGA for the 57711 and 57710 initializations values
(very small amount of code which is very helpful in the lab - less
than 30 lines).
The initialization is done via DMAE after the DMAE block is ready -
before it is ready, some of the initialization is done via PCI
configuration transactions (referred to as indirect write). A mutex
to protect the DMAE from being overlapped was added. There are few
new registers which needs to be initialized by SW - the full comment
for those registers is added to the register file. A place holder for
the 57711 (referred to as E1H) microcode was added- the microcode
itself is too big and it is split over the following 4 patches

New Link code:
Moving all the link related code (including the calculations, the
initialization of the MAC and PHY and the external PHY's code) into
a separated file. The changes from the code that used to be part of
bnx2x.c (now called bnx2x_main.c) are:
- Using separate structures for link inputs and link outputs to clearly
identify what was configured and what is the outcome
- Adding code to read external PHY FW version and print it as part of
ethtool -i
- Adding code to upgrade external PHY FW from ethtool -E with special
magic number - Changing the link down indication to ERR level
- Adding a lock on all PHY access to prevent an interrupt and
setting changes to overlap
- Adding support for emulation and FPGA (small chunk of code that really
helps in the lab) - Adding support for 1G on BCM8706 PHY
- Adding clear debug print incase of fan failure (the PHY type is now
"failure")

Use the same MSI-X handler to schedule NAPI. Change the dev_instance
void pointer to the bnx2_napi struct instead so we can have the proper
context for each MSI-X vector.
Add a new bnx2_poll_msix() that is optimized for handling MSI-X
NAPI polling of rx/tx work only. Remove the old bnx2_tx_poll() that
is no longer needed. Each MSI-X vector handles 1 tx and 1 rx ring.
The first vector handles link events as well.

Permit bonding to function rationally if max_bonds is set to
zero. This will load the module, but create no master devices (which can
be created via sysfs).
Requires some change to bond_create_sysfs; currently, the
netdev sysfs directory is determined from the first bonding device created,
but this is no longer possible. Instead, an interface from net/core is
created to create and destroy files in net_class.
Based on a patch submitted by Phil Oester <kernel@linuxaces.com>.
Modified by Jay Vosburgh to fix the sysfs issue mentioned above and to
update the documentation.

Support for sending multiple gratuitous ARPs during failovers
was added by commit:
commit 7893b2491a2d5f716540ac5643d78d37a7f6628b
Author: Moni Shoua <monis@voltaire.com>
Date: Sat May 17 21:10:12 2008 -0700
bonding: Send more than one gratuitous ARP when slave takes over
This change modifies that support to remove duplicated code,
add support for ARP monitor (the original only supported miimon), clear
the grat ARP counter in bond_close (lest a later "ifconfig up" immediately
start spewing ARPs), and add documentation for the module parameter.
Also updated driver version to 3.3.0.

under active-backup mode and when there's actual new_active slave,
have bond_change_active_slave() call the networking core to deliver
NETDEV_BONDING_FAILOVER event such that the fail-over can be notable
by code outside of the bonding driver such as the RDMA stack and
monitoring tools.
As the correct context of locking appropriate for notifier calls is RTNL
and nothing else, bond->curr_slave_lock and bond->lock are unlocked and
later locked again. This is ensured by the rest of the code to be safe
under backup-mode AND when new_active is not NULL.
Jay Vosburgh modified the original patch for formatting and fixed a
compiler error.

simplified the code of bond_change_active_slave() such that under
active-backup mode there's one "if (new_active)" test and the rest
of the code only does extra checks on top of it. This removed an
unneeded "if (bond->send_grat_arp > 0)" check and avoid calling
bond_send_gratuitous_arp when there's no active slave.
Jay Vosburgh made minor coding style changes to the orignal patch.
