There are many issues here. I will try to address them without writing something
so long that no one reads it. Just to be clear, my work with Realtek drivers is
as a volunteer and is done to provide a service to Linux users. The only thing I
get from Realtek is advance copies of drivers (sometimes), and sample cards for
PCI devices. With one exception, the USB devices in my possession have have been
purchased with my own funds.

1. Coverity errors in rtl8821ae: This driver was added to staging with
essentially no cleanup for several reasons. The first was as a favor to GregKH,
Linus, and roughly 1000 other users who recently got this hardware and want a
driver in 3.14. The second reason is that I do not yet have this hardware and
did not want to make any changes as all testing would have to be conducted by
Greg, and I think he has enough to do already. The driver uses mac80211, and it
should be ready to be submitted to the regular tree in time for 3.15. Most of
that cleanup has already been done. I should have sample hardware in the next
few weeks for testing.

2. rtl8187se: Andrea Morello has done the port to mac80211. I have tested that
version and found it stable. It should be in the regular wireless tree soon.

3. r8712u: This is the roughest of the drivers. As noted above, there is an
ongoing effort to add cfg80211 capability, but not to convert it to mac80211. It
is a softmac device, should be able to share code with rtl8192se, and it should
be converted to mac80211. I have no idea if and when that will happen. I am busy
with drivers for devices that are not otherwise supported in Linux. As to
littering the git logs with cleanups for this driver, I am not doing such
changes. I do not NACK other peoples efforts, but I do not participate.

4. Lack of response of Realtek to feedback: Development of drivers at Realtek is
split into two groups. The one that works with PCI devices is in China. They
have been very receptive to suggested changes, and I suspect that they study the
versions that have been committed as I see their unprompted implementation of
some of my changes. In addition, all new PCI-based drivers are mac80211 based.
The USB group is in Taiwan. Despite my efforts, very few, if any, of my
suggested changes have been adopted by them. None of their new drivers use mac80211.

5. Separate drivers for each chip: As I do not have, nor want, an NDA with
Realtek, I have no knowledge of the internal workings of the chips. As such, it
would be very difficult for me to write a combined driver for all the 802.11n
chips. I do notice that there are fundamental differences such as different
layouts of the DMA descriptors. A combined driver would require very many
branches based on chip number and would certainly execute much more slowly.

6. Staging drivers rtl8192e and rtl8192u: These drivers predate any association
I have with Realtek. In keeping with the Linux tradition of supporting old
hardware, they probably need to be kept. Driver rtl8192e is particularly
frustrating as it has a PCI ID in common with rtl8192ce. As the information
needed to determine which driver applies cannot be read from the PCI interface,
both drivers have to be loaded, tested, and the wrong one rejected late in the
module probe code.

I am trying to improve the quality of this pile of ****, but I am only one
person who was a life-long Fortran-coding scientist until I retired 15 years
ago. Since then, I have been learning C and kernel-style coding practices.
Certainly there is both a lot to do and a lot to learn.

Thanks for reading this far,

Really, any sort of cleanup is good, though... There are bugs I would
fix if the code didn't look like puke.

I seriously doubt there are performance issues with merging the drivers.

I greatly appreciate all of the work you have done here, with this
almost impossible task (no specs, random code drops from external
people, limited feedback loop from the company, etc.)

I blame the company for the situation here, not you at all, and its
great that the PCI division is doing much better now. Hopefully the USB
side will come around over time.

Quite frankly, merging drivers can be a f*cking pain. I would
seriously suggest avoiding it *unless* the hardware is literally
almost identical, or the drivers have been written with multi-chip
support from the ground up by people who actually understood the
hardware.

But the reason isn't performance - it's subtle breakage. Merged
drivers have a tendency to break support for chip A when you fix
something for chip B. And the end result is a driver that nobody
understands, and nobody can sanely test.

Sometimes it's simply better to leave old drivers alone.

Yes, I attach a cumulative patch for latest version of my work.

When I will send this asking for merge in kernel, I will split it in
some patches, because I also also included fix and improvements for
other already supported cards (not directly related to rtl8187se
support).

About this, I will produce separate patches for rtl8180 driver if
finally the drivers will be merged and also in case I'll split them..

Any suggestion/advice will be appreciated :)

Andrea,

In the case of the RTL8187SE driver, you only have three chips to deal with, two
of them are already in the driver, 802.11g devices are rather simple, and it is
extremely unlikely that any new devices will be added. For those reasons, I
think it is appropriate to make a combined driver. As there has been quite a bit
of testing on the current version, my vote is to stay with it.

I will test the latest revision soon. I'm not sure my laptop will hibernate, but
I will test that operation if I can.

If you've already merged them, and you think it works, keep it that way.

I was just saying that merging drivers isn't necessarily always the
right thing to do, and can be painful as hell.

Sorry, my fault.. you had already reported me the iowrite16 vs
iowrite8 for anaparam3 issue, but I forgot to fix it :(

If you are reasonably sure that a 16bits-wide write is OK on the
rtl8187b hardware (In reference code I have here only 8bits are
written), then I agree applying your fix, and I will leave unchanged
my modifications.
Otherwise, if you are unsure, I will revert thing in the common
rtl818x struct (switching back to 8bit type) and I simply make a cast
on rtl8187se, or I will use an union if possible, so the rtl8187b
driver remains unchanged.

On the other hand, for the remaining issues with changed names for
bitfield (the XXXX_SHIFT), I wil vote to fix the rtl8187 driver:
That names IMHO are wrong (misleading) and while fixing them should
help avoid future confusion, the fix is trivial enough that I'm really
confident not to broke anything.

I had already sent a patch for it:

http://marc.info/?l=linux-wireless&m=139033180125824&w=2

Whit this mail I intend to try to push it once more.

If it could be applied I prefer by far, otherwise, if it is too hassle
to handle it for the trivial thing it actually does, then I will
change back in rtl8180 driver..

Thank you

Somehow I missed this patch. Do you know if John Linville picked it up?

I'm not sure if the ANAPARAM3 register could handle a 16-bit write on an
RTL8187B. To be cautious, I wrote and have tested the attached patch using a
union. The patch includes a fix for an undefined symbol
(RTL818X_TX_CONF_HW_SEQNUM). With this patch my RTL8187SE and RTL8187B devices
both work.

Looks good. It would be best to submit the bugfixes first like where
you add error checking for pci_map_single(). Then the white space
changes. You add too many blank lines btw, you should never have two
consecutive blank lines. Don't add a blank line in the middle of the
declaration block or before a close curly brace '}' line. After that
maybe the patch to change "if (priv->r8185)" to
"if (priv->chip_family == RTL818X_CHIP_FAMILY_RTL8185)". Then the patch
to add rtl8225se support.

Some minor things below.

Don't include this twice. Only put one blank line, not two consecutive
blank lines.

This comment is out of date. RTL8180_NR_TX_QUEUES is 2. I haven't
really understood the changes to rtl8180_queues_map[]. It used to have
4 elements and now it only has 2. Is this change needed to support
rtl8225se or is it a separate bugfix which should go in a separate
patch?

Also this change which I have pulled out of context:

+ if (ring->entries - skb_queue_len(&ring->queue) < 2) {
+ if (prio != dev->queues)
+ ieee80211_stop_queue(dev, prio);
+ else
+ priv->beacon_queue_stop = 1;
+ }

This is a separate bugfix?

This is a temporary name to not conflight with rtl8180_write_phy()?

These don't go over the 80 character limit so we don't need the line
breaks. The casts are not needed either.

{
struct rtl8180_priv *priv = dev->priv;

rtl818x_iowrite8(priv, &priv->map->PHY[1], (data & 0xFF));
rtl818x_ioread8(priv, &priv->map->PHY[1]);

rtl818x_iowrite8(priv, &priv->map->PHY[2], ((data >> 8) & 0xFF));
rtl818x_ioread8(priv, &priv->map->PHY[2]);

rtl818x_iowrite8(priv, &priv->map->PHY[3], ((data >> 16) & 0xFF));
rtl818x_ioread8(priv, &priv->map->PHY[3]);

rtl818x_iowrite8(priv, &priv->map->PHY[0], addr);
}

Write it like this:

if (addr == 0xa && priv->chip_family == RTL818X_CHIP_FAMILY_RTL8185)
rb_mask = 0x7f;

If you really want to add parenthesis then do this:

if ((addr == 0xa) &&
(priv->chip_family == RTL818X_CHIP_FAMILY_RTL8185))
rb_mask = 0x7f;

Checkpatch.pl will complain that you should use netdev_warn() or
something.

I prefer max_t because it looks more deliberate and people won't think
you intended to use the minimum value.
