ice_parse_caps is used to parse both device and function capabilities. Currently, capabilities are printed with a cryptic "HW caps" prefix, which makes it difficult to distinguish whether the capabilities being printed are device or function capabilities. This patch makes a change to add a "func cap" prefix when printing function capabilities, and a "dev cap" prefix when printing device capabilities. This patch also changes some of the capability print strings for consistency. Signed-off-by:

Commit 3463688e6ced ("ice: Add more validation in ice_vc_cfg_irq_map_msg") added an assignment of vsi making the assignment during declaration unnecessary. Also, cleanup the declaration and assignment of irqmap_info to not use two lines in the variable declaration section. Signed-off-by:Bruce Allan <bruce.w.allan@intel.com> Signed-off-by:

Implement LLDP persistence across reboots, start and stop of LLDP agent. Add additional parameter to ice_aq_start_lldp and ice_aq_stop_lldp. Also change the ethtool private flag from "disable-fw-lldp" to "enable-fw-lldp". This change will flip the boolean logic of the functionality of the flag (on = enable, off = disable). The change in name and functionality is to differentiate between the pre-persistence and post-persistence states. Signed-off-by:

This reverts commit f8b99585. The reverted change instructed the QMan hardware block to fetch RX frame annotation and beginning of frame data to cache before the core would read them. It turns out that in rare cases, it's possible that a QMan stashing transaction is delayed long enough such that, by the time it gets executed, the frame in question had already been dequeued by the core and software processing began on it. If the core manages to unmap the frame buffer _before_ the stashing transaction is executed, an SMMU exception will be raised. Unfortunately there is no easy way to work around this while keeping the performance advantages brought by QMan stashing, so disable it altogether. Signed-off-by:

Adds support for validating hardware filter spec configured in firmware before offloading exact match flows. Use the new fw api FW_PARAM_DEV_FILTER_MODE_MASK to read the filter mode and mask from firmware. If the api isn't supported, then fall-back to older way of reading just the mode from indirect register. Signed-off-by:

With .ndo_set_rx_mode/temac_set_multicast_list() being called in atomic context (holding addr_list_lock), and temac_set_multicast_list() needing to access temac indirect registers, the mutex used to synchronize indirect register is a no-no. Replace it with a spinlock, and avoid sleeping in temac_indirect_busywait(). To avoid excessive holding of the lock, which is now a spinlock, the temac_device_reset() function is changed to only hold the lock for short periods. With timeouts, it could be holding the spinlock for more than 2 seconds. Signed-off-by:

When user has requested IFF_ALLMULTI or have set more than 4 multicast addresses, we should just use promiscuous mode, but not set it in flags, as it causes the interface to stay in promiscuous mode even when the non-IFF_PROMISC condition that caused promiscuous mode to be enabled has gone away.

All LXT PHYs implement the standard "power down" bit 11 of BMCR, so this patch adds support using the generic genphy_{suspend,resume} functions added by commit 0f0ca340 ("phy: power management support").

Currently, the hv_sock send() iterates once over the buffer, puts data into the VMBUS channel and returns. It doesn't maximize on the case when there is a simultaneous reader draining data from the channel. In such a case, the send() can maximize the bandwidth (and consequently minimize the cpu cycles) by iterating until the channel is found to be full. Perf data: Total Data Transfer: 10GB/iteration Single threaded reader/writer, Linux hvsocket writer with Windows hvsocket reader Packet size: 64KB CPU sys time was captured using the 'time' command for the writer to send 10GB of data. 'Send Buffer Loop' is with the patch applied. The values below are over 10 iterations. |--------------------------------------------------------| | | Current | Send Buffer Loop | |--------------------------------------------------------| | | Throughput | CPU sys | Throughput | CPU sys | | | (MB/s) | time (s) | (MB/s) | time (s) | |--------------------------------------------------------| | Min | 407 | 7.048 | 401 | 5.958 | |--------------------------------------------------------| | Max | 455 | 7.563 | 542 | 6.993 | |--------------------------------------------------------| | Avg | 440 | 7.411 | 451 | 6.639 | |--------------------------------------------------------| | Median | 446 | 7.417 | 447 | 6.761 | |--------------------------------------------------------| Observation: 1. The avg throughput doesn't really change much with this change for this scenario. This is most probably because the bottleneck on throughput is somewhere else. 2. The average system (or kernel) cpu time goes down by 10%+ with this change, for the same amount of data transfer. Signed-off-by:

Currently, the hv_sock buffer size is static and can't scale to the bandwidth requirements of the application. This change allows the applications to influence the socket buffer sizes using the SO_SNDBUF and the SO_RCVBUF socket options. Few interesting points to note: 1. Since the VMBUS does not allow a resize operation of the ring size, the socket buffer size option should be set prior to establishing the connection for it to take effect. 2. Setting the socket option comes with the cost of that much memory being reserved/allocated by the kernel, for the lifetime of the connection. Perf data: Total Data Transfer: 1GB Single threaded reader/writer Results below are summarized over 10 iterations. Linux hvsocket writer + Windows hvsocket reader: |---------------------------------------------------------------------------------------------| |Packet size -> | 128B | 1KB | 4KB | 64KB | |---------------------------------------------------------------------------------------------| |SO_SNDBUF size | | Throughput in MB/s (min/max/avg/median): | | v | | |---------------------------------------------------------------------------------------------| | Default | 109/118/114/116 | 636/774/701/700 | 435/507/480/476 | 410/491/462/470 | | 16KB | 110/116/112/111 | 575/705/662/671 | 749/900/854/869 | 592/824/692/676 | | 32KB | 108/120/115/115 | 703/823/767/772 | 718/878/850/866 | 1593/2124/2000/2085 | | 64KB | 108/119/114/114 | 592/732/683/688 | 805/934/903/911 | 1784/1943/1862/1843 | |---------------------------------------------------------------------------------------------| Windows hvsocket writer + Linux hvsocket reader: |---------------------------------------------------------------------------------------------| |Packet size -> | 128B | 1KB | 4KB | 64KB | |---------------------------------------------------------------------------------------------| |SO_RCVBUF size | | Throughput in MB/s (min/max/avg/median): | | v | | |---------------------------------------------------------------------------------------------| | Default | 69/82/75/73 | 313/343/333/336 | 418/477/446/445 | 659/701/676/678 | | 16KB | 69/83/76/77 | 350/401/375/382 | 506/548/517/516 | 602/624/615/615 | | 32KB | 62/83/73/73 | 471/529/496/494 | 830/1046/935/939 | 944/1180/1070/1100 | | 64KB | 64/70/68/69 | 467/533/501/497 | 1260/1590/1430/1431 | 1605/1819/1670/1660 | |---------------------------------------------------------------------------------------------| Signed-off-by:

The point of the pause-on-fail argument is to leave the setup as is after a test fails to allow a user to debug why it failed. Move the cleanup after posting the result to the user to make it so. Random names for the namespaces are not user friendly when trying to debug a failure. Make them simpler and more direct for the tests. Run cleanup at the beginning to ensure they are cleaned up if they already exist. Remove cleanup_done. There is no harm in doing cleanup twice; just ignore any errors related to not existing - which is already done. Signed-off-by:

Add fib_info_notify_update to walk the fib and send RTM_NEWROUTE notifications with NLM_F_REPLACE set for entries linked to a fib_info that have nh_updated flag set. This helper will be used by the nexthop code to notify userspace of routes that are impacted when a nexthop config is updated via replace. The new function and its helper are similar to how fib_flush and fib_table_flush work for address delete and link down events. This notification is needed for legacy apps that do not understand the new nexthop object. Apps that are nexthop aware can use the RTA_NH_ID attribute in the route notification to just ignore it. In the future this should be wrapped in a sysctl to allow OS'es that are fully updated to avoid the notificaton storm. Signed-off-by:
