This patch is int the new bnx2x_link files (C and H). The files are
still not used in this patch, only in the next one so the patch will
be small enough for the mailing list.

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.

Add hw_tx_cons_ptr and hw_rx_cons_ptr to speed up the retreival of
the tx and rx consumer index, since the MSI-X and default status
blocks have different structures.
Combine status_blk and status_blk_msix into a union. We'll only use
one type of status block for each vector.
Separate the code to detect more rx and tx work from the code to
detect link related work.

In preparation for multi-ring support, rx ring variables are now put
in a separate bnx2_rx_ring_info struct. With MSI-X, we can support
multiple rx rings.
The functions to allocate/free rx memory and to initialize rx rings
are now modified to handle multiple rings.

In preparation for multi-ring support, tx ring variables are now put
in a separate bnx2_tx_ring_info struct. Multi tx ring will not be
enabled until it is fully supported by the stack. Only 1 tx ring
will be used at the moment.
The functions to allocate/free tx memory and to initialize tx rings
are now modified to handle multiple rings.

By default, tun.c running in TUN_TUN_DEV mode will set the protocol of
packet to IPv4 if TUN_NO_PI is set. My program failed to work when I
assumed that the driver will check the first nibble of packet,
determine IP version and set the appropriate protocol.

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 7893b2491a
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.

The arch/ppc sub-tree has been removed in the powerpc git tree. The old
ibm_emac driver is no longer used by anything as a result of this. This
removes it, leaving the ibm_newemac driver as the proper driver to use for
PowerPC boards with the EMAC hardware.

The atl1 driver tries to determine the MAC address thusly:
- If an EEPROM exists, read the MAC address from EEPROM and
validate it.
- If an EEPROM doesn't exist, try to read a MAC address from
SPI flash.
- If that fails, try to read a MAC address directly from the
MAC Station Address register.
- If that fails, assign a random MAC address provided by the
kernel.
We now have a report of a system fitted with an EEPROM containing all
zeros where we expect the MAC address to be, and we currently handle
this as an error condition. Turns out, on this system the BIOS writes
a valid MAC address to the NIC's MAC Station Address register, but we
never try to read it because we return an error when we find the all-
zeros address in EEPROM.
This patch relaxes the error check and continues looking for a MAC
address even if it finds an illegal one in EEPROM.
