Seth David Schoen says: ==================== 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. ==================== Signed-off-by: -

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. Signed-off-by:

Ansuel Smith says: ==================== 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 ==================== Signed-off-by: -

Since the at803x share the same regs, it's assumed they are based on the same implementation. Make it part of the at803x PHY driver to skip having redudant code. Add initial support for qca8k internal PHYs. The internal PHYs requires special mmd and debug values to be set based on the switch revision passwd using the dev_flags. Supports output of idle, receive and eee_wake errors stats. Some debug values sets can't be translated as the documentation lacks any reference about them. Signed-off-by:

Clear MDIO_MASTER_EN bit from MDIO_MASTER_CTRL after read/write operation. The MDIO_MASTER_EN bit is not reset after read/write operation and the next operation can be wrongly interpreted by the switch as a mdio operation. This cause a production of wrong/garbage data from the switch and underfined bheavior. (random port drop, unplugged port flagged with link up, wrong port speed) Also on driver remove the MASTER_CTRL can be left set and cause the malfunction of any next driver using the mdio device.

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. Signed-off-by:
