Like the other drivers that were in the ISA i825xx family, the ni52
was rather rare, not widely used, and hence perhaps not as reliable
as the more mainstream ISA drivers that were heavily used. Given
that, it is chosen for retirement at this time as well.

This driver supported early to mid 1990's Zenith laptops, of the
2" thick variety. The driver was already dead 10+ years ago, but
we see this in the source:
----------------
/* 10/2002
[...]
Tested on a vintage Zenith Z-Note 433Lnp+. Probably broken on
anything else. Testers (and detailed bug reports) are welcome :-).
----------------
To clarify, a 433 translates into a 486 at 33MHz, and a system with
a default of 4MB RAM. I can't fault the noble effort to keep things
working a decade ago, but at this point in time, there is no valid
justification to continue carrying this driver along.
Note that there is no associated Space.c cleanup here since this
driver was using module_init to hook itself in.

These old drivers should not be confused with the very common PCI
cards that are supported by e100.c -- these older 10Mbit ISA only
drivers were not as commonly used as some of the other ISA drivers,
simply due to hardware availability and pricing.
Given the rarity of the hardware, and the subsequent less extensive
use of the drivers, it makes sense to obsolete them at this point
in time, along with other rare/experimental ISA drivers.

For those of us who were around in the early to mid 1990's, we
will remember that the i825xx ethernet support was not something
that was considered sufficiently vetted for 24/7 use.
Folks might be inclined to use *functional* ISA hardware on some
near expired P3 ISA machines for dedicated workhorse applications,
but the odds of using (and relying on) one of these old/experimental
drivers is essentially nil. So lets remove them.

The parallel port is largely replaced by USB, and even in the
day where these drivers were current, the documented speed was
less than 100kB/s. Let us not pretend that anyone cares about
these drivers anymore, or worse - pretend that anyone is using
them on a modern kernel.
As a side bonus, this is the end of legacy parallel port ethernet,
so we get to drop the whole chunk relating to that in the legacy
Space.c file containing the non-PCI unified probe dispatch.

It was amusing that linux was able to make use of this 1980's
technology on machines long past its intended lifespan, but
it probably should go now.
To set some context, the 3c501 was designed in the 1980's to be
used on 8088 PC-XT 8bit ISA machines. It was built using a large
number of discrete TTL components and truly looks like a relic
of the ancient past before large scale integration was common.
But from a functional point of view, the real issue, as stated
in the (also obsolete) Ethernet-HowTo, is that "...the 3c501 can
only do one thing at a time -- while you are removing one packet
from the single-packet buffer it cannot receive another packet,
nor can it receive a packet while loading a transmit packet."
You know things are not good when the Kconfig help text suggests
you make a cron job doing a ping every minute.
Hardware that old and crippled is simply not going to be used by
anyone in a time where 10 year old 100Mbit PCI cards (that are
still functional) are largely give-away items.

This driver was specific to a "professional workstation" line
of products from around 1993 that used the i82596 ethernet chip
as an on-board ethernet solution.
With a 486 processor, and the premium top of the line model maxing
out at a clock speed of 50MHz, we can safely retire this support.

The Apricot was a 486 PC with 4MB RAM, and an on-board ethernet
via an intel i82596 hard-wired to i/o 0x300.
Those who were using linux in the 1990's will recall that the
i82596 driver was not one of the more stable or widely used
drivers of its day. Combine that with the extremely limited
resources of the platform, and it is truly time to expire the
support for this thing.
There are some old m68k targets who were also using this chip,
so rather than poll the m68k user base, we simply cut out the
x86/Apricot support here in this commit.

The slave MII bus registered by the DSA code is using the parent MII bus
as part of its name (ds->master_mii_bus_id), in case the parent MII bus
name is already 16 characters long (such as d0072004.mdio-mi) we will
get the following WARN_ON in dsa_switch_setup() when calling
mdiobus_register():
[ 79.088782] ------------[ cut here ]------------
[ 79.093448] WARNING: at fs/sysfs/dir.c:536 sysfs_add_one+0x80/0xa0()
[ 79.099831] sysfs: cannot create duplicate filename
'/class/mdio_bus/d0072004.mdio-mi'
This is a genuine warning, because the DSA slave MII bus will also be
named d0072004.mdio-mi, and since MII_BUS_ID_SIZE is 17 characters long
(with null-terminator) the following will truncate the slave MII bus id:
snprintf(ds->slave_mii_bus->id, MII_BUS_ID_SIZE, "%s-%d:%.2x",
ds->master_mii_bus->id, ds->pd->sw_addr);
Fix this by using dsa-<switch index->:<sw_add> which is guaranteed to be
unique.

This patch add the support of proxy multicast, ie being able to build a static
multicast tree. It adds the support of (*,*) and (*,G) entries.
The user should define an (*,*) entry which is not used for real forwarding.
This entry defines the upstream in iif and contains all interfaces from the
static tree in its oifs. It will be used to forward packet upstream when they
come from an interface belonging to the static tree.
Hence, the user should define (*,G) entries to build its static tree. Note that
upstream interface must be part of oifs: packets are sent to all oifs
interfaces except the input interface. This ensures to always join the whole
static tree, even if the packet is not coming from the upstream interface.

The original intent of this file was to list limitations in
drivers/hardware relating to multicast use, back when some
modest hardware from the early 1990s did not support things
we might take for granted today.
I was intending to delete some now-gone MCA/token ring entries
in this file, but once I opened it, I found it only contained
information on the earliest (pre-2000) linux networking drivers.
Checking the git history shows that the file hasn't been touched
since 2005. Clearly nobody is actively consulting this file
as a meaningful reference.
Rather than add a "YES YES YES" line for all of the drivers we
currently have, lets just take advantage of the fact that nobody
is using the file to delete it.
This has the side benefit of not having to do a line-by-line
deletion of the file content as each older driver is expired.

The existing port isolation mode 'forward' will now verify that the adjacent
switch port supports the required reflective relay (RR) mode. This patch adds
the required error handling for the cases where enabling port isolation mode
'forward' can now fail.
Furthermore, once established, we never fall back from one of the port
isolation modes to a non-isolated mode without further user-interaction.
This includes cases where the isolation mode was enabled successfully, but
ceases to work e.g. due to configuration changes at the switch port.
Finally, configuring an isolation mode with the device being offline
will make onlining the device fail permanently upon errors encountered until
either errors are resolved or the isolation mode is changed by the user to a
different mode.

YOSHIFUJI Hideaki says:
====================
This series of changes basically clean up NDISC logic,
especially on sender side.
We originally do For NS/NA/RS:
1) build temporary ICMPv6 header
2) ndisc_build_skb() with temporary ICMPv6 header and rather
criptic arguments.
- Calculate total length and allocate sk_buff
- Build IPv6 header.
- copy ICMPv6 header, additional data and ND options.
- Fill-in ICMPv6 checksum.
Here, structures defined for message format was not used
at all, it is difficult to understand what is being sent,
and it was not generic.
3) __ndisc_send()
- Allocate temporary dst.
- Send it.
Several issues:
- We could not defer decision if we should/can send some ND
option.
- It is hard to see the packet format at a glance.
- ICMPv6 header was built as temporary variable, and then
copied to the buffer.
- Some code path for Redirect was not shared.
With these patches, we do:
1) Calculate (or estimate) message length and option length.
2) Allocate skb (via new ndisc_skb_alloc()).
3) Fill-in ICMPv6 message directly using compound literals.
4) Fill-in ICMPv6 checksum
5) Build IPv6 header (including length)
6) Send the packet (via ndisc_send_skb()).
- allocate temporary dst and send it.
- We can defer calculating real length of the packet.
For example, we can give up filling some option at when
filling in.
- Message is built directly without temporary buffer.
- Structures defined for message format is easier to understand
what is being built.
- NS/NA/RS/Redirect share same logic.
- Reduced code/data size:
text data bss dec hex filename
265407 14133 3488 283028 45194 old/net/ipv6/ipv6.o
264955 14109 3488 282552 44fb8 new/net/ipv6/ipv6.o
