Cleanup of dev_base list use, with the aim to simplify making device
list per-namespace. In almost every occasion, use of dev_base variable
and dev->next pointer could be easily replaced by for_each_netdev
loop. A few most complicated places were converted to using
first_netdev()/next_netdev().

The 5709 supports the one-shot MSI handler similar to some of the tg3
chips. In this mode, the MSI disables itself automatically until it
is re-enabled at the end of NAPI poll.

Hot-plug scripts can call bnx2_open() as soon as register_netdev() is
called in bnx2_init_one(). We need to call pci_set_drvdata() and
setup everything before calling register_netdev(). netif_carrier_off()
also needs to be moved to bnx2_open() to avoid race conditions with
the irq.

Herbert Xu conviced me that a new flag was overkill; every driver
currently overrides get_stats, so we might as well make the internal

get all 0 stats instead of "No statistics available".

I was going to say that eepro100's speedo_rx_link() does the same DMA
abuse as e100, but then I noticed one little detail: eepro100 sets both
EL (end of list) and S (suspend) bits in the RFD as it chains it to the
RFD list. e100 was only setting the EL bit. Hmmm, that's interesting.
That means that if HW reads a RFD with the S-bit set, it'll process
that RFD and then suspend the receive unit. The receive unit will
resume when SW clears the S-bit. There is no need for SW to restart
the receive unit. Which means a lot of the receive unit state tracking
code in the driver goes away.
So here's a patch against 2.6.14. (Sorry for inlining it; the mailer
I'm using now will mess with the word wrap). I can't test this on
XScale (unless someone has an e100 module for Gumstix :) . It should
be doing exactly what eepro100 does with RFDs. I don't believe this
change will introduce a performance hit because the S-bit and EL-bit go
hand-in-hand meaning if we're going to suspend because of the S- bit,
we're on the last resource anyway, so we'll have to wait for SW to
replenish.

The ucc_geth_memclean function can be called before the Tx BD rings, Rx
BD rings and associated socket buffers are allocated (for example if
ucc_fast_init fails). The current code doesn't check if p_tx_bd_ring[i]
is null, generating a kernel panic when trying to free the associated
socket buffers.
The function can also fail when accessing the uninitialized list_head
structures ugeth->group_hash_q and ugeth->ind_hash_q. In the current
implementation the list heads are initialized only when
maxGroupAddrInHash and maxIndAddrInHash are positive values, although I
think it's better to always initialize them.

Based partly on the gianfar driver, this patch fixes several
bugs which were causing NAPI to be completely unusable.
* An IRQ is still needed in NAPI, to kick off NAPI task,
and for Tx processing. Request the IRQ.
* If rx_work_limit = 0 we are not complete.
* While running Rx NAPI processing we must mask Rx events,
including Rx busy.
* ucc_geth_rx function does not need a lock.
Could lead to deadlock in NAPI case.
* There's no need to loop reading ucce multiple times in the ISR,
so while adding the call to schedule NAPI which was not there,
simplify the event processing into if-else format.
* Rx Busy now kicks off NAPI processing, while still
being counted as an error.

migrate ucc_geth to use the common phylib code.
There are several side effects from doing this:
o deprecate 'interface' property specification present
in some old device tree source files in
favour of a split 'max-speed' and 'interface-type'
description to appropriately match definitions
in include/linux/phy.h. Note that 'interface' property
is still honoured if max-speed or interface-type
are not present (backward compatible).
o compile-time CONFIG_UGETH_HAS_GIGA is eliminated
in favour of probe time speed derivation logic.
o adjust_link streamlined to only operate on maccfg2
and upsmr.r10m, instead of reapplying static initial
values related to the interface-type.
o Addition of UEC MDIO of_platform driver requires
platform code add 'mdio' type to id list
prior to calling of_platform_bus_probe (separate patch).
o ucc_struct_init introduced to reduce ucc_geth_startup
complexity.
