2022-10-31ptp: xgbe: convert to .adjfine and adjust_by_scaled_ppmJacob Keller
The xgbe implementation of .adjfreq is implemented in terms of a straight forward "base * ppb / 1 billion" calculation. Convert this driver to .adjfine and use adjust_by_scaled_ppm to calculate the new addend value.

2022-10-21amd-xgbe: add the bit rate quirk for Molex cablesRaju Rangoju
The offset 12 (bit-rate) of EEPROM SFP DAC (passive) cables is expected to be in the range 0x64 to 0x68. However, the 5 meter and 7 meter Molex passive cables have the rate ceiling 0x78 at offset 12. Add a quirk for Molex passive cables to extend the rate ceiling to 0x78.

2022-10-21amd-xgbe: fix the SFP compliance codes check for DAC cablesRaju Rangoju
The current XGBE code assumes that offset 6 of EEPROM SFP DAC (passive) cables is NULL. However, some cables (the 5 meter and 7 meter Molex passive cables) have non-zero data at offset 6. Fix the logic by moving the passive cable check above the active checks, so as not to be improperly identified as an active cable. This will fix the issue for any passive cable that advertises 1000Base-CX in offset 6.

2022-10-21amd-xgbe: enable PLL_CTL for fixed PHY modes onlyRaju Rangoju
PLL control setting(RRC) is needed only in fixed PHY configuration to fix the peer-peer issues. Without the PLL control setting, the link up takes longer time in a fixed phy configuration. Driver implements SW RRC for Autoneg On configuration, hence PLL control setting (RRC) is not needed for AN On configuration, and can be skipped. Also, PLL re-initialization is not needed for PHY Power Off and RRC commands. Otherwise, they lead to mailbox errors. Added the changes accordingly.

2022-06-13amd-xgbe: Use platform_irq_count()Jean-Philippe Brucker
The AMD XGbE driver currently counts the number of interrupts assigned to the device by inspecting the pdev->resource array. Since commit a1a2b7125e10 ("of/platform: Drop static setup of IRQ resource from DT core") removed IRQs from this array, the driver now attempts to get all interrupts from 1 to -1U and gives up probing once it reaches an invalid interrupt index. Obtain the number of IRQs with platform_irq_count() instead.

The conversion to the dma-mapping API in linux-2.6.11 was incomplete and left a virt_to_bus() call around. There have been a number of fixes for DMA mapping API abuse in this driver, but this one always slipped through.

2022-05-16net: allow gso_max_size to exceed 65536Alexander Duyck
The code for gso_max_size was added originally to allow for debugging and workaround of buggy devices that couldn't support TSO with blocks 64K in size. The original reason for limiting it to 64K was because that was the existing limits of IPv4 and non-jumbogram IPv6 length fields. With the addition of Big TCP we can remove this limit and allow the value to potentially go up to UINT_MAX and instead be limited by the tso_max_size value. So in order to support this we need to go through and clean up the remaining users of the gso_max_size value so that the values will cap at 64K for non-TCPv6 flows. In addition we can clean up the GSO_MAX_SIZE value so that 64K becomes GSO_LEGACY_MAX_SIZE and UINT_MAX will now be the upper limit for GSO_MAX_SIZE. v6: (edumazet) fixed a compile error if CONFIG_IPV6=n, in a new sk_trim_gso_size() helper. netif_set_tso_max_size() caps the requested TSO size with GSO_MAX_SIZE.

Since commit 94dd016ae538 ("bond: pass get_ts_info and SIOC[SG]HWTSTAMP ioctl to active device") the user could get bond active interface's PHC index directly. But when there is a failover, the bond active interface will change, thus the PHC index is also changed. This may break the user's program if they did not update the PHC timely. This patch adds a new hwtstamp_config flag HWTSTAMP_FLAG_BONDED_PHC_INDEX. When the user wants to get the bond active interface's PHC, they need to add this flag and be aware the PHC index may be changed. With the new flag. All flag checks in current drivers are removed.

2021-10-14ethernet: constify references to netdev->dev_addr in driversJakub Kicinski
This big patch sprinkles const on local variables and function arguments which may refer to netdev->dev_addr. Commit 406f42fa0d3c ("net-next: When a bond have a massive amount of VLANs...") introduced a rbtree for faster Ethernet address look up. To maintain netdev->dev_addr in this tree we need to make all the writes to it got through appropriate helpers. Some of the changes here are not strictly required - const is sometimes cast off but pointer is not used for writing. It seems like it's still better to add the const in case the code changes later or relevant -W flags get enabled for the build. No functional changes.

2021-08-13ethernet: fix PTP_1588_CLOCK dependenciesArnd Bergmann
The 'imply' keyword does not do what most people think it does, it only politely asks Kconfig to turn on another symbol, but does not prevent it from being disabled manually or built as a loadable module when the user is built-in. In the ICE driver, the latter now causes a link failure: aarch64-linux-ld: drivers/net/ethernet/intel/ice/ice_main.o: in function `ice_eth_ioctl': ice_main.c:(.text+0x13b0): undefined reference to `ice_ptp_get_ts_config' ice_main.c:(.text+0x13b0): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `ice_ptp_get_ts_config' aarch64-linux-ld: ice_main.c:(.text+0x13bc): undefined reference to `ice_ptp_set_ts_config' ice_main.c:(.text+0x13bc): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `ice_ptp_set_ts_config' aarch64-linux-ld: drivers/net/ethernet/intel/ice/ice_main.o: in function `ice_prepare_for_reset': ice_main.c:(.text+0x31fc): undefined reference to `ice_ptp_release' ice_main.c:(.text+0x31fc): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `ice_ptp_release' aarch64-linux-ld: drivers/net/ethernet/intel/ice/ice_main.o: in function `ice_rebuild': This is a recurring problem in many drivers, and we have discussed it several times befores, without reaching a consensus. I'm providing a link to the previous email thread for reference, which discusses some related problems. To solve the dependency issue better than the 'imply' keyword, introduce a separate Kconfig symbol "CONFIG_PTP_1588_CLOCK_OPTIONAL" that any driver can depend on if it is able to use PTP support when available, but works fine without it. Whenever CONFIG_PTP_1588_CLOCK=m, those drivers are then prevented from being built-in, the same way as with a 'depends on PTP_1588_CLOCK || !PTP_1588_CLOCK' dependency that does the same trick, but that can be rather confusing when you first see it. Since this should cover the dependencies correctly, the IS_REACHABLE() hack in the header is no longer needed now, and can be turned back into a normal IS_ENABLED() check. Any driver that gets the dependency wrong will now cause a link time failure rather than being unable to use PTP support when that is in a loadable module. However, the two recently added ptp_get_vclocks_index() and ptp_convert_timestamp() interfaces are only called from builtin code with ethtool and socket timestamps, so keep the current behavior by stubbing those out completely when PTP is in a loadable module. This should be addressed properly in a follow-up. As Richard suggested, we may want to actually turn PTP support into a 'bool' option later on, preventing it from being a loadable module altogether, which would be one way to solve the problem with the ethtool interface.
