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.

net: fec: using page pool to manage RX buffers This patch optimizes the RX buffer management by using the page pool. The purpose for this change is to prepare for the following XDP support. The current driver uses one frame per page for easy management. Added __maybe_unused attribute to the following functions to avoid the compiling warning. Those functions will be removed by a separate patch once this page pool solution is accepted. - fec_enet_new_rxbdp - fec_enet_copybreak The following are the comparing result between page pool implementation and the original implementation (non page pool). --- small packet (64 bytes) testing are almost the same --- no matter what the implementation is --- on both i.MX8 and i.MX6SX

enetc: Introduce basic PF and VF ENETC ethernet drivers ENETC is a multi-port virtualized Ethernet controller supporting GbE designs and Time-Sensitive Networking (TSN) functionality. ENETC is operating as an SR-IOV multi-PF capable Root Complex Integrated Endpoint (RCIE). As such, it contains multiple physical (PF) and virtual (VF) PCIe functions, discoverable by standard PCI Express. Introduce basic PF and VF ENETC ethernet drivers. The PF has access to the ENETC Port registers and resources and makes the required privileged configurations for the underlying VF devices. Common functionality is controlled through so called System Interface (SI) register blocks, PFs and VFs own a SI each. Though SI register blocks are almost identical, there are a few privileged SI level controls that are accessible only to PFs, and so the distinction is made between PF SIs (PSI) and VF SIs (VSI). As such, the bulk of the code, including datapath processing, basic h/w offload support and generic pci related configuration, is shared between the 2 drivers and is factored out in common source files (i.e. enetc.c). Major functionalities included (for both drivers): MSI-X support for Rx and Tx processing, assignment of Rx/Tx BD ring pairs to MSI-X entries, multi-queue support, Rx S/G (Rx frame fragmentation) and jumbo frame (up to 9600B) support, Rx paged allocation and reuse, Tx S/G support (NETIF_F_SG), Rx and Tx checksum offload, PF MAC filtering and initial control ring support, VLAN extraction/ insertion, PF Rx VLAN CTAG filtering, VF mac address config support, VF VLAN isolation support, etc. Signed-off-by: Claudiu Manoil <claudiu.manoil@nxp.com> Signed-off-by: David S.
