[netdrvr pcnet32] bug fixes

I would like to see a couple of the pcnet32 changes that I think we can
agree on be put into the trees so a couple of the potential defects can be
avoided. The following patch contains just these pieces. The only
controversial one is an arbitrary change in the number of iterations in a
while loop spinning on hardware state. No matter how this is done, I am
not especially fond of this bit of code as it has no reasonable error
recovery path -- however, as a half-way, incremental solution, increasing
the polling time should help as the 100 value was certainly found to be
insufficient. 1000 may not be sufficient either, but it is certainly no
worse.

Both of the other changes were hit in testing (and I belive the wmb() at a
customer even), so it would help reduce some debug if these go in. Any
feedback is appreciated - thanks.

[netdrvr bonding] fix ABI version control problem

This fix makes bonding not commit to a specific ABI version if the ioctl
command is not supported by bonding.

(It also removes the '\n' in the continuous printk reporting the link down
event in bond_mii_monitor - it got in there by mistake in our previous
patch set and caused log messages to appear funny in some situations).

[netdrvr bonding] fix long failover in 802.3ad mode

This patch fixes the bug reported by Jay on April 3rd regarding long
failover time when releasing the last slave in the active aggregator. The
fix, as suggested by Jay, is to follow the spec recommendation and send a
LACPDU to the partner saying this port is no longer aggregatable and
therefore trigger an immediate re-selection of a new aggregator instead of
waiting the entire expiration timeout.

[bonding] add rcv load balancing mode

This patch adds a new mode that enables receive load balancing for IPv4
traffic on top of the transmit load balancing mode. This capability is
achieved by intercepting and manipulating the ARP negotiation to teach
clients several MAC addresses for the bond and thus distribute incoming
traffic among all slaves with the highest link speed.

In order to function properly, slaves are required to be able to have
their MAC address set even while the interface is up since once the
primary slave looses its link, the new primary slave (and only it) must be
able to take over and receive the incoming traffic instead. If a
non-primary slave looses its link, ARP packets will be sent to all clients
communicating through it in order to teach them a replacement MAC address,
and the primary slave will be put in promiscuous mode for 10 seconds for
fault tolerance reasons.

This patch is against bonding-20030415, but must come only after the
locking scheme changing patch since it uses dev_set_promiscuity() that
would otherwise cause a system hang.

[bonding] much improved locking

This patch replaces the use of lock_irqsave/unlock_irqrestore in bonding
with lock/unlock or lock_bh/unlock_bh as appropriate according to context.
This change is based on a previous discussion regarding the fact that
holding a lock_irqsave doesn't prevent softirqs from running which can
cause deadlocks in certain situations. This new locking scheme has already
undergone massive testing cycle by our QA group and we feel it is ready
for release (some new modes and enhancements will not work properly
without it).

<shmulik.hen@intel.com> (03/05/23 1.1215.1.3)
[bonding] better 802.3ad mode control, some cleanup

This patch adds the lacp_rate module param to enable better control over
the IEEE 802.3ad mode. This param controls the rate at which the partner
system is asked to send LACPDUs to bonding.
Two options exist:
- slow (or 0) - LACPDUs are 30 seconds apart
- fast (or 1) - LACPDUs are 1 second apart
The default is slow (like most switches around).

There are also some code beautifications (mainly converting comments to C
style in code segments we added in the past).

<shmulik.hen@intel.com> (03/05/23 1.1215.1.2)
[bonding] ABI versioning

This patch adds user-land to kernel ABI version control in bonding to
restore backward compatibility between different versions of ifenslave and
the bonding module. It uses ethtool's GDRVINFO ioctl to pass the ABI
version number between ifenslave and the bonding module in both directions
so both the driver and the application can tell which partner they're
working against and take the appropriate measures when enslaving/releasing
an interface. The bonding module remembers the ABI version received from
the application, and from that moment on will deny enslave and release
commands from an application using a different ABI version, which means
that if you want to switch to an ifenslave with a different ABI version
(or with non at all), you'll first have to re-load the bonding module.

This patch also changes the driver/application versioning scheme to
contain 3 fields X.Y.Z with the follows meaning:
X - Major version - big behavior changes
Y - Minor version - addition of features
Z - Extra version - minor changes and bug fixes

There are also three minor bug fixes:
1. Prevent enslaving an interface that is already a slave.
2. Prevent enslaving if the bond is down.
3. In bond_release_all, save old value of current_slave before assigning
NULL to it to enable using it's original value later on.

This patch is against bonding-20030415.

(RCR remain 0x1c, write it as 0x1f don't work)

[PATCH] fix .text.exit error in drivers/net/r8169.c

In drivers/net/r8169.c the function rtl8169_remove_one is __devexit but

compile error when !CONFIG_HOTPLUG.

The fix is simple:

[bonding] Moved setting slave mac addr, and open, from app to the driver

This patch enables support of modes that need to use the unique mac
address of each slave. It moves setting the slave's mac address and
opening it from the application to the driver.
This breaks backward compatibility between the new driver and older
applications !
It also blocks possibility of enslaving before the master is up (to
prevent putting the system in an unstable state), and removes the code
that unconditionally restores all base driver's flags (flags are
automatically restored once all undo stages are done in proper order).
