The "reverse RMII" protocol name is a personal invention, derived from "reverse MII". Just like MII, RMII is an asymmetric protocol in that a PHY behaves differently than a MAC. In the case of RMII, for example: - the 50 MHz clock signals are either driven by the MAC or by an external oscillator (but never by the PHY). - the PHY can transmit extra in-band control symbols via RXD[1:0] which the MAC is supposed to understand, but a PHY isn't. The "reverse MII" protocol is not standardized either, except for this web document: https://www.eetimes.com/reverse-media-independent-interface-revmii-block-architecture/# In short, it means that the Ethernet controller speaks the 4-bit data parallel protocol from the perspective of a PHY (it acts like a PHY). This might mean that it implements clause 22 compatible registers, although that is optional - the important bit is that its pins can be connected to an MII MAC and it will 'just work'. In this discussion thread: https://lore.kernel.org/netdev/20210201214515.cx6ivvme2tlquge2@skbuf/ we agreed that it would be an abuse of terms to use the "RevMII" name for anything than the 4-bit parallel MII protocol. But since all the same concepts can be applied to the 2-bit Reduced MII protocol as well, here we are introducing a "Reverse RMII" protocol. This means: "behave like an RMII PHY". Signed-off-by:

Add an inbound policy filter which matches the HSR/PRP supervision MAC range and forwards to the CPU port without discarding duplicates. This is required to correctly populate time_in[A] and time_in[B] in the HSR/PRP node_table. Leave the policy disabled by default and enable/disable it when joining/leaving hsr. Signed-off-by:

The supplied buffer for the MAC address might not be aligned. Thus doing a 32bit (or 16bit) access could be on an unaligned address. For now, enetc is only used on aarch64 which can do unaligned accesses, thus there is no error. In any case, be correct and use the get/put_unaligned helpers. Signed-off-by:

Mat Martineau says: ==================== mptcp: Add timestamp support Enable the SO_TIMESTAMP and SO_TIMESTAMPING socket options for MPTCP sockets and add receive path cmsg support for timestamps. Patches 1, 2, and 5 expose existing sock and tcp helpers for timestamps (no new EXPORT_SYMBOLS()s). Patch 3 propagates timestamp options to subflows. Patch 4 cleans up MPTCP handling of SOL_SOCKET options. Patch 6 adds timestamp csmg data when receiving on sockets that have been configured for timestamps. Patch 7 adds self test coverage for timestamps. ==================== Signed-off-by: -

This is technically a false positive because there is an if statement above this one that checks skb->protocol for not being either ETH_P_IP{,V6}. However, it is more obvious to sink that into the if statement as an else branch, which makes the code clearer and fixes the warning. At the same time, move the "IS_ENABLED(CONFIG_IPV6)" into the else if condition so that the else branch of the preprocessor conditional can be shared, since there is no build failure with CONFIG_IPV6 disabled.

Alex Elder authored
Starting with IPA v4.5, IP payload checksum offload is implemented differently. Prior to v4.5, the IPA hardware appends an rmnet_map_dl_csum_trailer structure to each packet if checksum offload is enabled in the download direction (modem->AP). In the upload direction (AP->modem) a rmnet_map_ul_csum_header structure is prepended before each sent packet. Starting with IPA v4.5, checksum offload is implemented using a single new rmnet_map_v5_csum_header structure which sits between the QMAP header and the packet data. The same header structure is used in both directions. The new header contains a header type (CSUM_OFFLOAD); a checksum flag; and a flag indicating whether any other headers follow this one. The checksum flag indicates whether the hardware should compute (and insert) the checksum on a sent packet. On a received packet the checksum flag indicates whether the hardware confirms the checksum value in the payload is correct. Signed-off-by:

OFLD and CTRL TX queues can be stopped if there is no room in their DMA rings. If this happens, they're tried to be restarted later after having made some room in the corresponding ring. The tasks of restarting these queues were triggered using tasklets, but they can be replaced for workqueue works, getting them out of softirq context. This queues stop/restart probably doesn't happen often and they can be quite lengthy because they try to send all pending skbs. Moreover, given that probably the ring is not empty yet, so the DMA still has work to do, we don't need to be so fast to justify using tasklets/softirq instead of running in a thread. Signed-off-by:
