Disable periodic stats update background thread and update stats in background on demand when ndo_get_stats is called. Having a background thread running in the driver all the time is bad for power consumption and normally a user space daemon will query the stats once every specific interval, so ideally the background thread and its interval can be done in user space..

Add per-channel and global ethtool counters for NAPI. This helps us monitor and analyze performance in general. - ch[i]_poll: the number of times the channel's NAPI poll was invoked. - ch[i]_arm: the number of times the channel's NAPI poll completed and armed the completion queues. - ch[i]_aff_change: the number of times the channel's NAPI poll explicitly stopped execution on a cpu due to a change in affinity.

This patch enables UDP GSO support. We enable this by using two WQEs the first is a UDP LSO WQE for all segments with equal length, and the second is for the last segment in case it has different length. Due to HW limitation, before sending, we must adjust the packet length fields. We measure performance between two Intel(R) Xeon(R) CPU E5-2643 v2 @3.50GHz machines connected back-to-back with Connectx4-Lx (40Gbps) NICs. We compare single stream UDP, UDP GSO and UDP GSO with offload. Performance: | MSS (bytes) | Throughput (Gbps) | CPU utilization (%) UDP GSO offload | 1472 | 35.6 | 8% UDP GSO | 1472 | 25.5 | 17% UDP | 1472 | 10.2 | 17% UDP GSO offload | 1024 | 35.6 | 8% UDP GSO | 1024 | 19.2 | 17% UDP | 1024 | 5.7 | 17% UDP GSO offload | 512 | 33.8 | 16% UDP GSO | 512 | 10.4 | 17% UDP | 512 | 3.5 | 17% Signed-off-by:

Since a phy_device is added to the global mdio_bus list during phy_device_register(), but a phy_device's phy_driver doesn't get attached until phy_probe().

'sockaddr_len' is checked against various values when entering pppol2tp_connect(), to verify its validity. It is used again later, to find out which sockaddr structure was passed from user space. This patch combines these two operations into one new function in order to simplify pppol2tp_connect(). A new structure, l2tp_connect_info, is used to pass sockaddr data back to pppol2tp_connect(), to avoid passing too many parameters to l2tp_sockaddr_get_info(). Also, the first parameter is void* in order to avoid casting between all sockaddr_* structures manually. Signed-off-by:

Petr Machata says: ==================== Multipath tests for tunnel devices This patchset adds a test for ECMP and weighted ECMP between two GRE tunnels. In patches #1 and #2, the function multipath_eval() is first moved from router_multipath.sh to lib.sh for ease of reuse, and then fixed up. In patch #3, the function tc_rule_stats_get() is parameterized to be useful for egress rules as well. In patch #4, a new function __simple_if_init() is extracted from simple_if_init(). This covers the logic that needs to be done for the usual interface: VRF migration, upping and installation of IP addresses. Patch #5 then adds the test itself. Additionally in patch #6, a requirement to add diagrams to selftests is documented. ==================== Signed-off-by: -
Petr Machata authored
ASCII art diagrams are well suited for presenting the topology that a test uses while being easy to embed directly in the test file iteslf. They make the information very easy to grasp even for simple topologies, and for more complex ones they are almost essential, as figuring out the interconnects from the script itself proves to be difficult. Therefore state the requirement for topology ASCII art in README. Signed-off-by:

Petr Machata authored
The function simple_if_init() does two things: it creates a VRF, then moves an interface into this VRF and configures addresses. The latter comes in handy when adding more interfaces into a VRF later on. The situation is similar for simple_if_fini(). Therefore split the interface remastering and address de/initialization logic to a new pair of helpers __simple_if_init() / __simple_if_fini(), and defer to these helpers from simple_if_init() and simple_if_fini().

The IP addresses of tunnel endpoint at H3 are set at the VLAN device $h3.555. Therefore when test_gretap_untagged_egress() sets vlan 555 to egress untagged at $swp3, $h3's rp_filter rejects these packets. The test then spuriously fails. Therefore turn off net.ipv4.conf.{all, $h3}.rp_filter. Fixes: 9c7c8a82 ("selftests: forwarding: mirror_gre_vlan_bridge_1q: Add more tests") Signed-off-by:
