[PATCH net v4 01/13] net/8390: Remove redundant make dependencies

[Finn Thain]

The hydra, zorro8390 and mcf8390 drivers all #include "lib8390.c" and
have no need for 8390.o. modinfo confirms no dependency on 8390.ko.
Drop the redundant dependency from the Makefile. objdump confirms
that this has no effect on the module binaries.

[PATCH net v4 00/13] Fixes, cleanup and modernization for some legacy ethernet NIC drivers

[Finn Thain]

This patch series adds Driver Model support to Mac NIC drivers,
fixes some bugs, removes some dead code and adopts netif_* calls to
reduce code duplication.

This series results in a reduction of about 100 lines of code.

It has been tested on a variety of Macs, with coverage for the
changes to lib8390.c, mac8390.c, macsonic.c, sonic.c and macmace.c.

Much of this patch series depends on the NuBus modernization series
which has been merged for 4.16-rc.

Changes since v3:
- Rebased on current nubus code.
- Renamed some more struct nubus_rsrc pointers that were misleadingly
  called 'dev' and 'ndev'.
- Removed an unused struct member from the mac89x0 driver.
- Dropped gratuitous log message changes (capitalization, punctuation
  etc.) so that the old messages can still be grep'd.
- Improved patch descriptions.
- Revised code style to reduce checkpatch.pl noise.
- Addressed two more 8390 logging issues.
- Added a new patch to remove redundant 8390.o dependencies.
- Re-ordered some patches for easier cherry picking.

Changes since v2:
- Modernized the Mac NIC drivers by adopting the Linux Driver Model.
- Used dev_foo() in NuBus drivers.
- Removed device probe messages logged after register_netdev().

Changes since v1:
- Retained the once_is_enough test in mac89x0.c.
- Added tested-by tags.
- Moved netdev_info() call to correct branch in macmace.c.

[PATCH net v4 11/13] net/macsonic: Convert to nubus_driver

[PATCH net v4 10/13] net/mac8390: Fix log messages

[Finn Thain]

Use dev_foo() to log the slot number instead of the unexpanded "eth%d"
format string.
Disambiguate the two identical "Card type %s is unsupported" messages.

[PATCH net v4 07/13] net/mac89x0: Fix and modernize log messages

[Finn Thain]

Fix log message fragments that no longer produce the desired output
since the behaviour of printk() was changed.
Add missing printk severity levels.
Drop deprecated "out of memory" message as per checkpatch advice.

[PATCH net v4 06/13] net/mac89x0: Convert to platform_driver

[Finn Thain]

Apparently these Dayna cards don't have a pseudoslot declaration ROM
which means they can't be probed like NuBus cards.

[PATCH net v4 04/13] net/macmace: Fix and clean up log messages

[Finn Thain]

Don't log the unexpanded "eth%d" format string.
Log the chip revision in the probe message (consistent with mace.c).
Drop redundant debug messages for FIFO events recorded in the
interface statistics (also consistent with mace.c).

[PATCH net v4 02/13] net/8390: Fix msg_enable patch snafu

[Finn Thain]

The lib8390 module parameter 'msg_enable' doesn't do anything useful:
it causes an ancient version string to be logged.

Remove redundant code that logs the same string.

In ne.c and wd.c, the value of ei_local->msg_enable is used before
being assigned. Use ne_msg_enable and wd_msg_enable, respectively.

Most of the other 8390 drivers never assign ei_local->msg_enable.
Use the 'msg_enable' module parameter from lib8390 as the default
value.

Eliminate the pointless static and local variables.

Clean up an indentation mistake.

All of these issues originated from the same patch.

[PATCH net v4 03/13] net/smc9194: Remove bogus CONFIG_MAC reference

[Finn Thain]

AFAIK the only version of smc9194.c with Mac support is the one in the
linux-mac68k CVS repo, which never made it to the mainline.

Despite that, from v2.3.45, arch/m68k/config.in listed CONFIG_SMC9194
under CONFIG_MAC. This mistake got carried over into Kconfig in v2.5.55.
(See pre-git era "[PATCH] add m68k dependencies to net driver config".)

[PATCH net v4 13/13] net/sonic: Replace custom debug logging with netif_* calls

[Finn Thain]

Eliminate duplicated debug code by moving it into the core driver.
Don't log the only valid silicon revision number (it's in the source).

[PATCH net v4 12/13] net/sonic: Clean up and modernize log messages

[Finn Thain]

Add missing printk severity levels by adopting pr_foo() calls for the
platform_driver and dev_foo() calls for the nubus_driver.
Avoid KERN_CONT usage as per advice from checkpatch.
Avoid #ifdef around printk calls.
Don't log driver probe messages after calling register_netdev().

Not true.

You need to look at the various netif_*() et al. message logging
interfaces, they check "p->msg_enable" to determine which messages to
print.

I'm not applying this, sorry.

Just for the record, I consider these kinds of ancient driver cleanups
painful to review, and unless they allow some ugly global kernel API
to be improved or removed such changes have very little gain.

In fact, most of them have a good chance to break things.

It is especially a dubious sequence when you cluster so many of these
things together into a large patch series.

If you are really serious about fixing real bugs, post these one at a
time, very slowly, for us to review properly and apply.

Thank you.

I think you have overlooked those modules which offer no way to set 
p->msg_enable, i.e. ax88796, axnet_cs, etherh, hydra, mac8390, mcf8390, 
pcnet_cs and zorro8390.

The apne, ne, ne2k-pci, smc-ultra, stnic, and wd modules are not at issue 
here because they define their own msg_enable parameters and they also 
assign p->msg_enable accordingly.

OK. When there are no users, I'll send you no patches.

But even then, I may continue to send patches to other maintainers who may 
be open to the possibility of unforeseen future uses of the body of 
contributed code under their care.

You saw the tested-by tags, right? Anyway, if you consider my previous 
work, I believe you'll find that I've fixed more bugs than I've 
introduced.

Sorry if that gave the wrong impression. Doing that made my workflow 
easier.

Please don't feel like I'm trying to pressure you to expedite this.

FWIW, this submission was arranged so that you might cherry-pick the first 
N patches, for some satisfactory value of N.

I will split up this series by driver (8390, sonic, etc) so it's more 
clear which patches are independent and which patches can be reviewed 
together.

Thanks.

I agree.

And considering the out-of-tree Nubus PowerMac port, this check just makes 
the driver less portable.

I'll resubmit these patches with the changes you have suggested (here and 
elsewhere). Thanks for your review.

BTW, would you be willing to review the rest of this series sometime? I 
ask because David has voiced concerns about code quality, and your 
"reviewed-by" tag speaks volumes.

Then that's a bug, we have a very simple easy to implement interface
for setting this (ethtool).

And by adding the simple hook, you will make these older drivers
easier to debug for the few people still using them.

Have you considered that implementing the ethtool hooks in the core driver 
might allow removal of all 8390 driver 'msg_enable' module parameters and 
msglevel ethtool hooks added by c45f812f0280, excepting those in the core 
driver? But even if we did that, it seems to me that we still need this 
patch.

The missing set_msglevel ethtool hooks and the msg_enable bugs patched 
here are separate issues inasmuchas the lib8390.c module parameter called 
'msg_enable' presently controls only the version message whereas the 
ethtool hooks cannot control the version message logging at all.

I'm not against improving ethtool support. Would you please explain how 
doing so (one way or another) would alter this patch?

No, because the module parameter lets you set the default msg level at
the time the driver loads, so you can control messages printed very
early on before it is practical to invoke ethtool and set the msg
level.

This is why most drivers have this module parameter, and implement
such a scheme.

Among the 8390 drivers, so far only ne2k-pci implements that scheme.

This patch implements that scheme for ax88796 and etherh as well, by 
making better use of the msg_enable module parameter in lib8390.c.

The axnet_cs and pcnet_cs modules lack the msglevel ethtool ops and the 
msg_enable module parameters.

The remaining nine modules lack just the ethtool ops. If you like I will 
write additional patches to implement the missing ethtool ops or module 
parameters or both (?)

This small patch already addresses the use-case in which the end-user 
needs to enable (for example) probe messages for some or all 8390 drivers.

Thoughts?
