The srom array in the board data is only being used in the device probe
routines. The probe also only uses the first 6 bytes of an array
we spend 512ms reading 128 bytes from. Change to reading the
MAC area directly to the MAC address structure.
As a side product, we rename the read_srom_word to dm9000_read_eeprom
to bring it into line with the rest of the driver. No change is made
to the delay in this function, which will be dealt with in a later

The phy read and write routines call udelay() with the board
lock held, and with the posibility of IRQs being disabled. Since
these delays can be up to 500usec, and are only required as we
have to save the chip's address register.
To improve the behaviour, hold the lock whilst we are writing
and then restore the state before the delay and then repeat
the process once the delay has happened.

Remove the timer based MII phy polling, as this is
currently broken with the new EEPROM code that now
uses mutexes to protect the phy access.
This will need to be replaced in the future by some
form of mutex safe mechanism for reading the MII
phy status.
The replacement has not been done here as changing
this patch, which is early in the sequence has quite
a knock-on effect. Once this series is merged, then
a new presentation of an patch to poll the MII link

Use the flags in the IRQ resource to specify the type of
IRQ being requested, so that systems which do not have
level-based interrupts, or change the interrupt in some
other way can specify this without making an #ifdef mess
in the driver.
This is specifically designed to undo the change in commit
4e4fc05a2b which hardwires the
type for everyone but blackfin to IRQT_RISING, which breaks
all a number of Simtec boards which use (and setup in the
bootloader) active low IRQs.
Note, although there where originally objections due to
the use of IORESOURCE_IRQ and IRQT_ flags not sharing the
same definition, at least <include/linux/interrupt.h> notes
these are the same.

1. Add common code for stopping queue.
2. No need to call netif_stop_queue followed by netif_wake_queue (and
infact a netif_start_queue could have been used instead), instead
call stop_queue if required, and remove code under USE_GTS macro.
3. There is no need to check for netif_queue_stopped, as the network
core guarantees that for us (I am sure every driver could remove
that check, eg e1000 - I have tested that path a few billion times
with about a few hundred thousand qstops but the condition never
hit even once).

The e1000 driver stores the content of the PCI resources into
unsigned long's before ioremapping. This breaks on 32 bits
platforms that support 64 bits MMIO resources such as ppc 44x.
This fixes it by removing those temporary variables and passing
directly the result of pci_resource_start/len to ioremap.
The side effect is that I removed the assignments to the netdev
fields mem_start, mem_end and base_addr, which are totally useless
for PCI devices.

Add support for dual network (net_device) interface so that ethernet
and wireless can own separate ethX interfaces.
V2
- Fix the bug that bringing down and up the interface keeps rx
disabled.
- Make 'gelic_net_poll_controller()' extern , as David Woodhouse
pointed out at the previous submission.
- Fix weird usage of member names for the rx descriptor chain
V1
- Export functions which are convenient for both interfaces
- Move irq allocation/release code to driver probe/remove handlers
because interfaces share interrupts.
- Allocate skbs by using dev_alloc_skb() instead of netdev_alloc_skb()
as the interfaces share the hardware rx queue.
- Add gelic_port struct in order to abstract dual interface handling
- Change handlers for hardware queues so that they can handle dual
{source,destination} interfaces.
- Use new NAPI functions
This is a prerequisite for the new PS3 wireless support.
