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 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.

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.

Keep enc28j60 chips in low-power mode when they're not in use.
At typically 120 mA, these chips run hot even when idle; this
low power mode cuts that power usage by a factor of around 100.
This version provides a generic routine to poll a register until
its masked value equals some value ... e.g. bit set or cleared.
It's basically what the previous wait_phy_ready() did, but this
version is generalized to support the handshaking needed to
enter and exit low power mode.

The ibm_newemac driver requires ether_crc to be defined. Apparently it is
possible to generate a .config without CONFIG_CRC32 set which causes the

A few general categories:
1) ieee80211_has_* tests if particular fctl bits are set, the helpers are de
in the same order as the fctl defines:
A combined _has_a4 was also added to test when both FROMDS and TODS are set.
2) ieee80211_is_* is meant to test whether the frame control is of a certain
ftype - data, mgmt, ctl, and two special helpers _is_data_qos, _is_data_pres
which also test a subset of the stype space.
When testing for a particular stype applicable only to one ftype, functions
like ieee80211_is_ack have been added. Note that the ftype is also being
checked in these helpers. They have been added for all mgmt and ctl stypes
in the same order as the STYPE defines.
3) ieee80211_get_* is meant to take a struct ieee80211_hdr * and returns a
pointer to somewhere in the struct, see get_SA, get_DA, get_qos_ctl.
The intel wireless drivers had helpers that used this namespace, convert the
all to use the new helpers and remove the byteshifting as they were defined
in cpu-order rather than little-endian.

mac80211_hwsim is a Linux kernel module that can be used to simulate
arbitrary number of IEEE 802.11 radios for mac80211 on a single
device. It can be used to test most of the mac80211 functionality and
user space tools (e.g., hostapd and wpa_supplicant) in a way that
matches very closely with the normal case of using real WLAN
hardware. From the mac80211 view point, mac80211_hwsim is yet another
hardware driver, i.e., no changes to mac80211 are needed to use this
testing tool.
