Hi,
This patch introduces a generic netdev_ioaddr and converts natsemi and
8139too drivers to use it.
With the recent __iomem annotations, the network drivers need to either
invent this wrapper (like natsemi has done) or duplicate the IO base
address in their private data (similar to 8139too). Therefore, lets
make netdev_ioaddr generic before it is all over the place.
Pekka

This patch converts 8139too driver to use netdev_ioaddr.
Not tested as I don't have access to the hardware right now. Compiles and
passes sparse checks.

This casting around sounds like a bad idea. Either add another
void __iomem *mmioaddr;
member to struct net_device, or better move that completely into the
driver-private structure which seems the better level of abstraction.

NAK. ->base_addr casting is a Bad Idea(tm) and natsemi "solution" isn't
(thanks for spotting that crap in natsemi, though; will fix...)
Note that there is no such thing as "generic IO base address" - it _is_
private and in the best case current ->base_addr is a scratch register
probably used for something vaguely connected with some IO, but it's
really up to driver...

Yup, I thought about that after I sent the patch. However, as it stands now,
many network drivers use netdev->base_addr for just that. Perhaps it should
be nuked completely instead?

I thinks so. With ifmap, SIOCSIFMAP, ifr_map, mem_end etc.,
irq, if_port, dma.

SIOCSIFMAP is unfortunate, but legitimate - it passes more or less
opaque structure to driver and lets driver interpret it.
SIOCGIFMAP, OTOH, is really bad - among other things, for many drivers
it leaks ioremapped addresses to userland. And *that* is a LARTable
offense - it's an information that makes no sense whatsoever for userland
code and should never be exposed, just as with any kernel pointers.
What uses ->base_addr from the data returned by SIOCGIFMAP?

Hi,
This patch adds a mmioaddr field with proper void __iomem* type to
netdev_private struct and removes the ns_ioaddr function that messes around
with netdev->base_addr.
I tested this with actual hardware. The code also passes sparse checks.

ifconfig I think:

Interrupt:10 Base address:0x4000
With this driver it happens to be MMIO address.
I understand presenting this value to users might have some value:
it can help determine the physical port/card for a given netdev.
But it should be something like a description text set by the driver
(ie. containing PCI bus/device, or even ISA address for ISA non-PnP
card, possibly with other information).
It seems while some devices use SIOCGIFMAP (ie. by setting the fields
in netdev struct), support for SIOCSIFMAP doesn't make sense for most
hardware.
Drivers using SIOCSIFMAP (selecting media only?):
arch/cris/arch-v10/drivers/ethernet.c: dev->set_config = e100_set_config;
drivers/net/au1000_eth.c: dev->set_config = &au1000_set_config;
drivers/net/sis900.c: net_dev->set_config = &sis900_set_config;

drivers/net/wan/sdla.c: dev->set_config = sdla_set_config;
drivers/net/wireless/ray_cs.c: dev->set_config = &ray_dev_config;
I think I would mark this stuff obsolete, and remove when the drivers
are updated (if they need an update at all, they may support
ethtool/mii-tool already).

It seems that the user can also setup dev->base_addr with "netdev="
kernel parameter before a driver starts probing (for example
drivers/net/appletalk/cops.c). Should we get rid of "netdev=" too and
push preconfiguring down to the drivers that actually use it?

Of course 0x4000 was an IO (non-MMIO) address.

Sure, cops.io= should be fine. Or cops.hw=io,irq,mem etc.
Still, this is an issue with non-PnP ISA cards only.

Cops already exposes base address and irq as module parameters and yet
it calls netdev_boot_setup_check() to check "netdev=" so I assume
there's a reason for that. Perhaps something like the (untested) patch
below would make more sense?

IMHO partially: base_addr etc should go from the core (to driver's
local structs if needed). I think no general netdev-setup thing is
needed, we have module parameters and library functions.
No ioctl for such things is needed either.
/sbin/ifconfig shouldn't mess with hardware data such as I/O address,
IRQ etc. - it should be a configuration tool for software protocols,
not for hardware (i.e. as /sbin/ip is).
My opinion of course.

FWIW I am running this patch on my box. ifconfig doesn't mind but I am
not sure about the rtnetlink part. I can start stabbing other drivers
if the maintainers are interested in this cleanup...
