Renesas Ethernet AVB driver proper Ethernet AVB includes an Gigabit Ethernet controller (E-MAC) that is basically compatible with SuperH Gigabit Ethernet E-MAC. Ethernet AVB has a dedicated direct memory access controller (AVB-DMAC) that is a new design compared to the SuperH E-DMAC. The AVB-DMAC is compliant with 3 standards formulated for IEEE 802.1BA: IEEE 802.1AS timing and synchronization protocol, IEEE 802.1Qav real- time transfer, and the IEEE 802.1Qat stream reservation protocol. The driver only supports device tree probing, so the binding document is included in this patch. Based on the original patches by Mitsuhiro Kimura.

drivers/net: remove all references to obsolete Ethernet-HOWTO This howto made sense in the 1990s when users had to manually configure ISA cards with jumpers or vendor utilities, but with the implementation of PCI it became increasingly less and less relevant, to the point where it has been well over a decade since I last updated it. And there is no value in anyone else taking over updating it either. However the references to it continue to spread as boiler plate text from one Kconfig file into the next. We are not doing end users any favours by pointing them at this old document, so lets kill it with fire, once and for all, to hopefully stop any further spread. No code is changed in this commit, just Kconfig help text. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com> Signed-off-by: David S. Miller <davem@davemloft.net>

ethernet: fix PTP_1588_CLOCK dependencies 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.

Renesas Ethernet-TSN device driver.
Renesas Ethernet AVB driver proper Ethernet AVB includes an Gigabit Ethernet controller (E-MAC) that is basically compatible with SuperH Gigabit Ethernet E-MAC. Ethernet AVB has a dedicated direct memory access controller (AVB-DMAC) that is a new design compared to the SuperH E-DMAC. The AVB-DMAC is compliant with 3 standards formulated for IEEE 802.1BA: IEEE 802.1AS timing and synchronization protocol, IEEE 802.1Qav real- time transfer, and the IEEE 802.1Qat stream reservation protocol. The driver only supports device tree probing, so the binding document is included in this patch. Based on the original patches by Mitsuhiro Kimura.
