====================
Treat IPv4 lowest address as ordinary unicast address
Treat the lowest address in a subnet (the address within the subnet
which contains all 0 bits) as an ordinary unicast address instead
of as a potential second broadcast address. For example, in subnet
192.168.17.24/29, which contains 8 addresses, make address 192.168.17.24
usable as a normal unicast address (while continuing to support
192.168.17.31 as a broadcast address).
Since EVERY network number or subnet formerly had its host number 0
reserved, this patchset adds 1 more usable host address to every network
and subnet (i.e., 2^(32-n)-1 instead of 2^(32-n)-2 addresses available
for assignment on each IPv4 /n subnet). For small subnets, this is a
significant gain; instead of 6 usable host addresses, a /29 would now
contain 7, a 16% increase.
The reserving of host number 0 for broadcast came about in RFC 1122 from
1989 (page 31, "IP addresses are not permitted to have the value 0 or -1
for any of the <Host-number>, <Network-number>, or <Subnet-number>
fields (except in the special cases listed above)" and page 66, "There
is a class of hosts [4.2BSD Unix and its derivatives, but not 4.3BSD]
that use non-standard broadcast address forms, substituting 0 for -1.
All hosts SHOULD recognize and accept any of these non-standard
broadcast addresses as the destination address of an incoming
datagram."). This has been repeated in subsequent RFCs, always with
backwards-compatibility rationales. Network troubles (broadcast storms)
ensued when some early hosts on a LAN treated the lowest address as
unicast and others treated it as broadcast. Multiple 1989 changes to IP
successfully prevented these. The key was adding the layering violation
rule requiring hosts to ignore all IP datagrams with unicast destination
addresses that were received in low-level (Ethernet) broadcasts. That
change is still in effect, and this patchset does not alter it. All
operating systems since 4.3BSD, including all the current BSD OSes, now
use the standard IP broadcast address. 4.2BSD has been obsolete for
more than 30 years, and all modern hosts ignore hardware broadcasts
containing unicast IP addresses, so there is no modern likelihood of
broadcast storms even when hosts disagree on the unicast vs. broadcast
status of a given address.
Tests with this patchset show that other Linux hosts on the local segment
simply ignore a host numbered with the lowest address, both for incoming
and outgoing packet purposes. They don't interoperate with it, but they
also don't cause broadcast storms or any other malfunction. If patched,
they have no trouble interoperating with a host at the lowest address.
Unmodified "distant" hosts that are not on the same segment successfully
interoperate, as long as the gateway on the local segment, and the local
host itself using the lowest address, have this patch. (Distant hosts
have no way of knowing whether a given address is the lowest address
in a faraway network segment, so they treat it no differently than any
other unicast address.) This means that each local site can change this
behavior locally, resulting immediately in global interoperability with
the newly usable lowest local address.
Modern software and documentation continues to use the definition of the
directed, or "net-directed", broadcast address as "a host ID of all one
bits". The Internet no longer gets any benefit from having two different
broadcast addresses usable on every Ethernet segment. I have not been
able to find any documentation that suggests that users or software should
ever intentionally use the all-zero form, or that justifies it other than
as a historic Berkeleyism. RFCs 1112, 1812, and 3021 state that hosts and
routers need to maintain compatibility with the old form -- but they give
no rationale other than the past existence of the 4.2BSD behavior.
We're happy to provide more historical details or information about
behavior of other systems in this regard by e-mail or as future patches
to kernel documentation files.

With the use of the qca8k dsa driver, some problem arised related to
port status detection. With a load on a specific port (for example a
simple speed test), the driver starts to behave in a strange way and
garbage data is produced. To address this, enlarge the sleep delay and
address a bug for the reg offset 31 that require additional delay for
this specific reg.

====================
Multiple improvement to qca8k stability
Currently qca8337 switch are widely used on ipq8064 based router.
On these particular router it was notice a very unstable switch with
port not link detected as link with unknown speed, port dropping
randomly and general unreliability. Lots of testing and comparison
between this dsa driver and the original qsdk driver showed lack of some
additional delay and values. A main difference arised from the original
driver and the dsa one. The original driver didn't use MASTER regs to
read phy status and the dedicated mdio driver worked correctly. Now that
the dsa driver actually use these regs, it was found that these special
read/write operation required mutual exclusion to normal
qca8k_read/write operation. The add of mutex for these operation fixed
the random port dropping and now only the actual linked port randomly
dropped. Adding additional delay for set_page operation and fixing a bug
in the mdio dedicated driver fixed also this problem. The current driver
requires also more time to apply vlan switch. All of these changes and
tweak permit a now very stable and reliable dsa driver and 0 port
dropping. This series is currently tested by at least 5 user with
different routers and all reports positive results and no problems.
Changes v6:
- Fix spelling mistake
- Change ms to ns (confirmed by datasheet)
Changes v5:
- Removed mdio patch (sent separetly to try to reduce the series)
I know it was asked to reduced this series since it big, but rework
the new changes to skip and error check looks wrong. Since half of them
are actually already reviewed I think it's better to keep this series as is.
- Improve rgmii configurable patch
- Move qca8k phy dedicated driver to at803x phy driver
- Add support for dedicated internal mdio driver for qca8k
Changes v4:
- Use iopoll for busy_wait function
- Better describe and split some confusing commits
- Fix bad rgmii delay configurable patch
- Drop phy generic patch to pass flags with phylink_connect_phy
- Add dsa2 patch to declare mdio node in the switch node
- Add dsa patch to permit dsa driver to declare custom get_phys_mii_mask
Some background about the last 2 patch.
The qca8k switch doesn't have a 1:1 map between port reg and phy reg.
Currently it's used a function to convert port to the internal phy reg.
I added some patch to fix this.
- The dsa driver now check if the mdio node is present and use the of variant
of the mdiobus_register
- A custom phy_mii_mask is required as currently the mask is generated from
the port reg, but in our case the mask would be different as it should be
generated from the phy reg. To generalize this I added an extra function
that driver can provide to pass custom phy_mii_mask.
Changes v3:
- Revert mdio writel changes (use regmap with REGCACHE disabled)
- Split propagate error patch to 4 different patch
Changes v2:
- Implemented phy driver for internal PHYs
I'm testing cable test functions as I found some documentation that
actually declare regs about it. Problem is that it doesn't actually
work. It seems that the value set are ignored by the phy.
- Made the rgmii delay configurable
- Reordered patch
- Split mdio patches to more specific ones
- Reworked mdio driver to use readl/writel instead of regmap
- Reworked the entire driver to make it aware of any read/write error.
- Added phy generic patch to pass flags with phylink_connect_phy
function

The legacy qsdk code used a different delay instead of the max value.
Qsdk use 1 ns for rx and 2 ns for tx. Make these values configurable
using the standard rx/tx-internal-delay-ps ethernet binding and apply
qsdk values by default. The connected gmac doesn't add any delay so no
additional delay is added to tx/rx.
On this switch the delay is actually in ns so value should be in the
1000 order. Any value converted from ps to ns by dividing it by 1000
as the switch max value for delay is 3ns.
