Vivien Didelot says: ==================== net: dsa: mv88e6xxx: probe compatible This patchset factorizes the legacy and new SMI probing and abstracts the switch register accesses. This simplifies adding support for new chips or alternative register accesses. This will allow us to use a compatible chip info to describe how to access the SMI device and its switch ID register at probe time. For the legacy probe, we fix the compatible info to 88E6085. For the MDIO probe, we will use the compatible info from the device node data. All patches are reviewed. Changes since v4: - fix debug printing (was 'val' instead of '*val') Changes since v3 [3]: - better register access abstraction using the chip structure Changes since v2 [2]: - do not guess compatible model in legacy probe - add low level SMI API using a chip structure - allocate before probe and detection - add 3 cosmetic patches Changes since v1 [1]: - merge style fix from Ben Dooks - add Acked-by/Reviewed-by tags - drop one compatible string per model - detect the SMI device based on the compatible info - add an SMI ops structure [1] https://lkml.org/lkml/2016/6/8/1201 [2] https://lkml.org/lkml/2016/6/14/671 [3] https://lkml.org/lkml/2016/6/17/995 ==================== Signed-off-by:

When the SMI address of the switch chip is zero, the chip assumes to be the only one on the SMI master bus and thus responds to all its known SMI devices addresses (port registers, Global2, etc.) When its SMI address is not zero, some chips (e.g. 88E6352) use an indirect access through two SMI Command and Data registers. Other models (e.g. 88E6060) using less than 16 internal SMI addresses always use a direct access. Add a capability flag to describe chips supporting the (indirect) Multi-chip Addressing Mode, and a low-level API to access the registers via SMI. Other accesses (like Ethernet management frames) may be added later. Signed-off-by:

The switch ID is located at address 0x3 of every Port Registers bank. But not all Marvell switches have their Port Registers SMI Addresses starting at 0x10. 88E6060 starts at 0x8 and 88E6390 starts at 0x0. Add this data in the info structure and use it in the detection code. Signed-off-by:

After allocating the chip structure, pass it a compatible info pointer. The compatible info structure will be used later to describe how to access the switch registers and where to read the switch ID. For the standard MDIO probe, get it from the device node data. For the legacy DSA driver probing, pass it the 88E6085 info. Signed-off-by:

Add an helper function to isolate SMI specific assignments and checks. This function will later help choosing the different SMI accesses based of the compatible info. Since the chip structure is already allocated in the legacy probe, use the mv88e6xxx_reg_read access routine instead of __mv88e6xxx_reg_read. Signed-off-by:

The chip smi_mutex mutex is used to protect the access to the internal switch registers, not only the Multi-chip Addressing Mode, as commented. Since we will isolate SMI-specific pieces of code, avoid the confusion now by renaming smi_mutex to reg_lock. No functional changes here. Signed-off-by:

The mixed assignments, allocations and registrations in the probe code make it hard to follow the logic and figure out what is DSA or chip specific.

Eric Dumazet says: ==================== ipv6: better traceroute support in sit and gre In commit ca15a078 ("sit: generate icmpv6 error when receiving icmpv4 error"), Oussama Ghorbel added minimal support for SIT tunnels to generate ICMPv6 messages when receiving ICMPv4 messages. This patch series extends this to GRE tunnels. It also adds support for ICMPV6_TIME_EXCEED. Partial support for RFC 4884 is added, to forward ICMP Multi-part extensions eventually found in the ICMPv4 message. v2: replaced an overlapping memcpy() by memmove() ==================== Signed-off-by:

Eric Dumazet authored
When receiving an ICMPv4 message containing extensions as defined in RFC 4884, and translating it to ICMPv6 at SIT or GRE tunnel, we need some extra manipulation in order to properly forward the extensions. This patch only takes care of Time Exceeded messages as they are the ones that typically carry information from various routers in a fabric during a traceroute session. It also avoids complex skb logic if the data_len is not a multiple of 8. RFC states : The "original datagram" field MUST contain at least 128 octets. If the original datagram did not contain 128 octets, the "original datagram" field MUST be zero padded to 128 octets. In practice routers use 128 bytes of original datagram, not more. Initial translation was added in commit ca15a078 ("sit: generate icmpv6 error when receiving icmpv4 error") Signed-off-by:

Geert Uytterhoeven contributes a patch that adds a file patterns for CAN device tree bindings to MAINTAINERS. A patch by Alexander Aring fixes warnings when building without proc support. A patch by me improves the sample point calculation. Marek Vasut's patch converts the slcan driver to use CAN_MTU. A patch by William Breathitt Gray converts the tscan1 driver to use module_isa_driver. Two patches by Maximilian Schneider for the gs_usb driver fix coding style and add support for set_phys_id callback. 5 patches by Oliver Hartkopp add support for CANFD to the bcm.

There is no reason in rx_descs property because davinici_cpdma driver splits pool of descriptors equally between tx and rx channels. That is, if number of descriptors 256, 128 of them are for rx channels. While receiving, the descriptor is freed to the pool and then allocated with new skb. And if in DT the "rx_descs" is set to 64, then 128 - 64 = 64 descriptors are always in the pool and cannot be used, for tx, for instance. It's not correct resource usage, better to set it to half of pool, then the rx pool can be used in full. It will not have any impact on performance, as anyway, the "redundant" descriptors were unused. Signed-off-by:

Update the source address selection to consider the real output route as opposed to the VRF route that sends packets to the VRF device first (ie., implement get_saddr6 similar to the IPv4 method) and update the IPv6 address selection to consider L3 domains and preference for addresses on the VRF device). ==================== Signed-off-by:
