When there's a Tx timeout for a queue which belongs to a PFC enabled TC, then it's not because the queue is hung but because PFC is in action. In PFC, peer sends a pause frame for a specified period of time when its buffer threshold is exceeded (due to congestion). Netdev on the other hand checks if ACK is received within a specified time for a TX packet, if not, it'll invoke the tx_timeout routine. Signed-off-by:

Implement promiscuous support for VF VSIs. Behaviour of promiscuous support is based on VF trust as well as the, introduced, vf-true-promisc flag. A trusted VF with vf-true-promisc disabled will be the default VSI, which means that all traffic without a matching destination MAC address in the device's internal switch will be forwarded to this VF VSI. A trusted VF with vf-true-promisc enabled will go into "true promiscuous mode". This amounts to the VF receiving all ingress and egress traffic that hits the device's internal switch. An untrusted VF will only receive traffic destined for that VF. The vf-true-promisc-support flag cannot be toggled while any VF is in promiscuous mode. This flag should be set prior to loading the iavf driver or spawning VF(s). Signed-off-by:

The flash memory for the ice hardware contains a block of information used for link management called the Netlist module. As this essentially represents another section of firmware, add its version information to the output of the driver's .info_get handler. This includes both a version and the first few bytes of a hash of the module contents. fw.netlist -> the version information extracted from the netlist module fw.netlist.build-> first 4 bytes of the hash of the contents, similar to fw.mgmt.build Signed-off-by:

Oleksij Rempel says: ==================== provide KAPI for SQI This patches are extending ethtool netlink interface to export Signal Quality Index (SQI). SQI provided by 100Base-T1 PHYs and can be used for cable diagnostic. Compared to a typical cable tests, this value can be only used after link is established. changes v3: - rename __ethtool_get_sqi* to linkstate_get_sqi*. And move this functions to the net/ethtool/linkstate.c - protect linkstate_get_sqi* with locking changes v2: - use u32 instead of u8 for SQI - add SQI_MAX field and callbacks - some style fixes in the rst. - do not convert index to shifted index. ==================== Signed-off-by:

Signal Quality Index is a mandatory value required by "OPEN Alliance SIG" for the 100Base-T1 PHYs [1]. This indicator can be used for cable integrity diagnostic and investigating other noise sources and implement by at least two vendors: NXP[2] and TI[3].

Add support for XRC-SRQ's and XRC-QP's for upper layer driver. We maintain separate bitmaps for resource management for srq and xrc-srq, However, the range in FW is one, The xrc-srq's are first and then the srq's follow. Therefore we maintain a srq-id offset. v2: perform cleanups if XRC bitmpas allocation fail. Signed-off-by:

Currently, psample can only send the packet bits after decapsulation. The tunnel information is lost. Add the tunnel support. If the sampled packet has no tunnel info, the behavior is the same as before. If it has, add a nested metadata field named PSAMPLE_ATTR_TUNNEL and include the tunnel subfields if applicable. Increase the metadata length for sampled packet with the tunnel info. If new subfields of tunnel info should be included, update the metadata length accordingly. Signed-off-by:

Jeff Kirsher says: ==================== 1GbE Intel Wired LAN Driver Updates 2020-05-19 This series contains updates to igc only. Sasha cleans up the igc driver code that is not used or needed. Vitaly cleans up driver code that was used to support Virtualization on a device that is not supported by igc, so remove the dead code. Andre renames a few macros to align with register and field names described in the data sheet. Also adds the VLAN Priority Queue Fliter and EType Queue Filter registers to the list of registers dumped by igc_get_regs(). Added additional debug messages and updated return codes for unsupported features. Refactored the VLAN priority filtering code to move the core logic into igc_main.c. Cleaned up duplicate code and useless code. ==================== Acked-by:

Native ->setsockopt() handling of these options (MCAST_..._SOURCE_GROUP and MCAST_{,UN}BLOCK_SOURCE) consists of copyin + call of a helper that does the actual work. The only change needed for ->compat_setsockopt() is a slightly different copyin - the helpers can be reused as-is. Signed-off-by:

Parallel to what the native setsockopt() does, except that unlike the native setsockopt() we do not use memdup_user() - we want the sockaddr_storage fields properly aligned, so we allocate 4 bytes more and copy compat_group_filter at the offset 4, which yields the proper alignments. Signed-off-by:

now we can do MCAST_MSFILTER in compat ->getsockopt() without playing silly buggers with copying things back and forth. We can form a native struct group_filter (sans the variable-length tail) on stack, pass that + pointer to the tail of original request to the helper doing the bulk of the work, then do the rest of copyout - same as the native getsockopt() does.

pass the userland pointer to the array in its tail, so that part gets copied out by our functions; copyout of everything else is done in the callers. Rationale: reuse for compat; the array is the same in native and compat, the layout of parts before it is different for compat. Signed-off-by:

We want to get rid of compat_mc_[sg]etsockopt() and to have that stuff handled without compat_alloc_user_space(), extra copying through userland, etc. To do that we'll need ipv4 and ipv6 instances of ->compat_[sg]etsockopt() to manipulate the 32bit variants of mcast requests, so we need to move the definitions of those out of net/compat.c and into a public header. This patch just does a mechanical move to include/net/compat.h Signed-off-by:

The whole ethertype filtering code is implemented in igc_ethtool.c and mixes logic from ethtool and core parts. This patch refactors it so core logic is moved to igc_main.c, aligning the ethertype filtering code organization with the rest of the filtering code from the driver (MAC address and VLAN priority). Besides moving code to igc_main.c, this patch also does some minor improvements to the code. Below are some highlights. In case all filters are already in use and the user tries to add another filter, we return -ENOSPC instead of -EINVAL so a more meaningful error code is provided. This also aligns with the behavior implemented in MAC address filtering code. With this code refactoring, 'etype_bitmap' array in struct igc_adapter and 'etype_reg_index' in struct igc_nfc_filter are not needed anymore and are removed. Log messages are added to help debugging the ethertype filtering code. Signed-off-by:

Christoph Hellwig says: ==================== add a new ->ndo_tunnel_ctl method to avoid a few set_fs calls v2 both the ipv4 and ipv6 code have an ioctl each that can be used to create a tunnel using code that doesn't live in the core kernel or ipv6 module. Currently they call ioctls on the tunnel devices to create these, for which the code needs to override the address limit, which is a "feature" I plan to get rid of. Instead this patchset adds a new ->ndo_tunnel_ctl that can be used for the tunnel configuration using struct ip_tunnel_parm. The method is either invoked from a helper that does the uaccess and can be wired up as ndo_do_ioctl method, or directly from the magic IPV4/6 ioctls that create tunnels with kernel space arguments. Changes since v2: - properly propagate errors in ipip6_tunnel_prl_ctl ==================== Signed-off-by:
