When enable/disable tso, the driver tries to access the hardware register, but this operation will cause the port unavalible when there is traffic. This patch tries to enable TSO when initialize, then control tso through TSE bit in transmit descriptor. Signed-off-by:

The default coalesce timeout is 3us, which is will cause CPU usage is too high. This patch change it to 50us in order to reduce CPU usage and the value makes sure network latency also meets requirement. Signed-off-by:

The default sbm config parameter leaves little buffer when there is heavy traffic, which will cause packets drop. This patch changes them to make enough buffers for handling packets. Signed-off-by:

When hns_nic_poll_rx_skb alloc skb fail, it will break receive cycle and read new fbd_num to start new receive cycle. It recomputes cycle num is fbd_num minus clean_count, actually this cycle num is too big because it drop out receive cycle. It brings about the port unavailable. So we will goto out when alloc skb fail to fix this bug. Signed-off-by:

The default driver sets anchor led bit to 0 when link down, actually, the anchor bit should be set to 1, so fixes it when link status is down. Secondly, change the return value of cpld_set_led_id to 0, which means leave the cpld to control led blink frequece other than the driver itself. Signed-off-by:

For debug-ports,there are two non-synchronized processes: Speed-Auto-Negotiation and Link-Update-Status. The two processes are towed by two different state machines. Bond reads the speed when link up, but the speed maybe not update the right value at that time.That make for bond's wrong speed. Thus only one state machine should be used and if phy_state_machine is used, it does not need to do hns_nic_update_link_status(). Signed-off-by:

When run ethtool cmd(ethtool -t ethx) again and again for a long time, it will be probabilistically fail. The PHYs' registers may be on different pages, so it must be switch to the right page before setting PHYs' registers. And __lb_up() calls phy_start() to startup the PHYs device, but this function may change Copper Control Register(Page 0, Register 0) to an other value. It would cause phy loopback test fail. if we remove phy_start(), we have to remove the relative phy_stop(), phy_disconnect() when doing phy loopback to keep the phy stay in right status. Reported-by:

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:
