[PATCH] zd1211rw: Defer firmware load until first ifup
While playing with the firmware a while back, I discovered a way to
access the device's entire address space before the firmware has been
loaded.
Previously we were loading the firmware early on (during probe) so that
we could read the MAC address from the EEPROM and register a netdevice.
Now that we can read the EEPROM without having firmware, we can defer
firmware loading until later while still reading the MAC address early
on.
This has the advantage that zd1211rw can now be built into the kernel --
previously if this was the case, zd1211rw would be loaded before the
filesystem is available and firmware loading would fail.
Firmware load and other device initialization operations now happen the
first time the interface is brought up.
Some architectural changes were needed: handling of the is_zd1211b flag
was moved into the zd_usb structure, MAC address handling was obviously
changed, and a preinit_hw stage was added (the order is now: init,
preinit_hw, init_hw).

a race in airo. airo finds a free interface name, then initializes the card
and finally registers the interface. Another device may get the same name
in the meantime.
The reason airo gets its name early is to use it in informative printks and
to name the resources it requests. The printks will be just fine without
the interface name and the resources can use the driver's name - that's
what other network drivers do anyway.
One of the talkative functions is setup_card(). It is called once before
registration and can be called later again. Let's have an empty dev->name
during the first call, so it doesn't print the ugly "airo(eth%d)" message.

bonding / ipv6: no addrconf for slaves separately from master
At present, when a device is enslaved to bonding, if ipv6 is
active then addrconf will be initated on the slave (because it is closed
then opened during the enslavement processing). This causes DAD and RS
packets to be sent from the slave. These packets in turn can confuse
switches that perform ipv6 snooping, causing them to incorrectly update
their forwarding tables (if, e.g., the slave being added is an inactve
backup that won't be used right away) and direct traffic away from the
active slave to a backup slave (where the incoming packets will be
dropped).
This patch alters the behavior so that addrconf will only run on
the master device itself. I believe this is logically correct, as it
prevents slaves from having an IPv6 identity independent from the
master. This is consistent with the IPv4 behavior for bonding.
This is accomplished by (a) having bonding set IFF_SLAVE sooner
in the enslavement processing than currently occurs (before open, not
after), and (b) having ipv6 addrconf ignore UP and CHANGE events on
slave devices.
The eql driver also uses the IFF_SLAVE flag. I inspected eql,
and I believe this change is reasonable for its usage of IFF_SLAVE, but
I did not test it.

operation.
This is an optimised implementation of early printk() for the DECstation.
After the recent conversion to a MIPS-specific generic routine using a
character-by-character output the performance dropped significantly.
This change reverts to the previous speed -- even at 9600 bps of the
serial console the difference is visible with a naked eye; I presume for a
framebuffer it is even worse (it may depend on exactly which one is used
though).
Additionally the change includes a fix for a problem that the old
implementation had -- the format used would not actually limit the length
of the string output. This new implementation uses a local buffer to deal
with it -- even with this additional copying it is much faster than the
generic function.
Plus this driver is registered much earlier than the generic one,
allowing one to see critical messages, such as one about an incorrect CPU
setting used, that are produced beforehand. :-)
