So far we've succeeded in operating without keeping a copy of the phy-mode in the driver, since we already have the static config and we can look at the xMII Mode Parameters Table which already holds that information. But with the SJA1110, we cannot make the distinction between sgmii and 2500base-x, because to the hardware's static config, it's all SGMII. So add a phy_mode property per port inside struct sja1105_private.

Looking at the SGMII PCS from SJA1110, which is accessed indirectly through a different base address as can be seen in the next patch, it appears odd that the address accessed through indirection still references the base address from the SJA1105S register map (first MDIO register is at 0x1f0000), when it could index the SGMII registers starting from zero. Except that the 0x1f0000 is not a base address at all, it seems. It is 0x1f << 16 | 0x0000, and 0x1f is coding for the vendor-specific MMD2. So, it turns out, the Synopsys PCS implements all its registers inside the vendor-specific MMDs 1 and 2 (0x1e and 0x1f). This explains why the PCS has no overlaps (for the other MMDs) with other register regions of the switch (because no other MMDs are implemented). Change the code to remove the SGMII "base address" and explicitly encode the MMD for reads/writes. This will become necessary for SJA1110 support.

The SJA1105 R and S switches have 1 SGMII port (port 4). Because there is only one such port, there is no "port" parameter in the configuration code for the SGMII PCS. However, the SJA1110 can have up to 4 SGMII ports, each with its own SGMII register map. So we need to generalize the logic.

Since commit f2f3e09396be ("net: dsa: sja1105: be compatible with "ethernet-ports" OF node name"), DSA supports the "ethernet-ports" name for the container node of the ports, but the sja1105 driver doesn't, because it handles some device tree parsing of its own. Add the second node name as a fallback. Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>

This is a complement to commit aa6dd211 ("inet: use bigger hash table for IP ID generation"), but focusing on some specific aspects of IPv6. Contary to IPv4, IPv6 only uses packet IDs with fragments, and with a minimum MTU of 1280, it's much less easy to force a remote peer to produce many fragments to explore its ID sequence. In addition packet IDs are 32-bit in IPv6, which further complicates their analysis. On the other hand, it is often easier to choose among plenty of possible source addresses and partially work around the bigger hash table the commit above permits, which leaves IPv6 partially exposed to some possibilities of remote analysis at the risk of weakening some protocols like DNS if some IDs can be predicted with a good enough probability. Given the wide range of permitted IDs, the risk of collision is extremely low so there's no need to rely on the positive increment algorithm that is shared with the IPv4 code via ip_idents_reserve(). We have a fast PRNG, so let's simply call prandom_u32() and be done with it. Performance measurements at 10 Gbps couldn't show any difference with the previous code, even when using a single core, because due to the large fragments, we're limited to only ~930 kpps at 10 Gbps and the cost of the random generation is completely offset by other operations and by the network transfer time. In addition, this change removes the need to update a shared entry in the idents table so it may even end up being slightly faster on large scale systems where this matters. The risk of at least one collision here is about 1/80 million among 10 IDs, 1/850k among 100 IDs, and still only 1/8.5k among 1000 IDs, which remains very low compared to IPv4 where all IDs are reused every 4 to 80ms on a 10 Gbps flow depending on packet sizes.

While investigating the clang `ge` uninitialized variable report, it was discovered the default switch would have unintended consequences. Due to the switch to __phy_modify, the driver would modify the ID values in the default scenario. Fix this by promoting the interface mode switch and aborting when the mode is not a supported RGMII mode. This prevents the `ge` and `fe` variables from ever being used uninitialized.
