2023-05-12ethernet: T3891: add conditional code-path when doing speed/duplex changesChristian Breunig
There is no need for the backend code to call ethtool and try to change speed or duplex settings every time there is a change in the interface configuration, but no change for the speed/duplex subnodes. This also makes the commit itself faster when working with ethernet interfaces. Bonus: no repeating CLI messages that the driver does not support speed/duplex changes, as we do not change anything here. Extension to commit f2ecc9710 ("ethernet: T3891: honor auto-negotiation support per NIC")
2023-05-04ethernet: T3891: honor auto-negotiation support per NICChristian Breunig
Not all drivers/NICs or combination of NIC + transceiver support auto- negotiation. The current auto-negotiation capability is evaluated and taken into account when applying spped/duplex settings. If auto-negotiation is not supported - we skip the setting to avoid errors during configuration.
2023-01-13ethernet: rps: T4928: adjust to Kernel ABI changes #2Christian Breunig
Fix ValueError: Unknown format code 'x' for object of type 'str' added in commit c0ffb8ba4e663 ("ethernet: rps: T4928: adjust to Kernel ABI changes").
2023-01-12ethernet: rps: T4928: adjust to Kernel ABI changesChristian Breunig
In the past we could simply set all bits for all CPUs even if they did not exist. With 6.1.y Kernel series this is no longer possible and the input data is validated against the available number of CPUs.
2022-09-26ethernet: T4689: support asymetric RFS configuration on multiple interfacesChristian Poessinger
The initial implementation from commit ac4e07f9 ("rfs: T4689: Support RFS (Receive Flow Steering)") always adjusted the global rps_sock_flow_entries configuration. So if RFS was enabled for one NIC but not the other - it did not work. According to the documentation: RFS is only available if the kconfig symbol CONFIG_RPS is enabled (on by default for SMP). The functionality remains disabled until explicitly configured. The number of entries in the global flow table is set through: /proc/sys/net/core/rps_sock_flow_entries The number of entries in the per-queue flow table are set through: /sys/class/net/<dev>/queues/rx-<n>/rps_flow_cnt Both of these need to be set before RFS is enabled for a receive queue. Values for both are rounded up to the nearest power of two. The suggested flow count depends on the expected number of active connections at any given time, which may be significantly less than the number of open connections. We have found that a value of 32768 for rps_sock_flow_entries works fairly well on a moderately loaded server. This commit sets rps_sock_flow_entries via sysctl on bootup leafing the RFS configuration to the interface level.

The initial implementation in commit 9fb9e5cade ("ethernet: T3171: add CLI option to enable RPS (Receive Packet Steering)" only changed the CPU affinity for RX queue 0. This commit takes all RX queues into account.

2022-08-29ethernet: T4653: bugfix copy-paste when processing NIC offloadingChristian Poessinger
Commit 31169fa8a763e ("vyos.ifconfig: T3619: only set offloading options if supported by NIC") added the new implementation which handles NIC offloading. Unfortunately every single implementation was copied from "gro" which resulted in a change to gro for each offloading option - thus options like lro, sg, tso had no effect at all. It all comes down to copy/paste errors ... one way or another.
2022-04-11T4327: ignore PermissionError caused by ethtool spee/duplex/autoneg settingDaniil Baturin
Certain NICs seem to fail to report that they don't support speed/duplex setting, so they look as if it's supported, but the command fails in practice. It's probably better to preserve a working config in that case.

Interface will still be visible to the operating system.
2021-09-10ethernet: T3802: not all NICs support reading speed/duplex settings in all ↵Christian Poessinger
states Turns out an AX88179 USB 3.0 NIC does not support reading back the speed and duplex settings in every operating state. While the NIC is beeing initialized, reading the speed setting will return: $ cat /sys/class/net/eth6/speed cat: /sys/class/net/eth6/speed: Invalid argument Thus if this happens, we simply tell the system that the current NIC speed matches the requested speed and nothing is changed at this point in time.

Move the two implementations to get the driver name of a NIC from ethernet.py and ethtool.py to only ethtool.py. (cherry picked from commit 07840977834816b69fa3b366817d90f44b5dc7a7)

2021-08-31vyos.ethtool: T3163: purify code to read and change flow-control settingsChristian Poessinger
It makes no sense to have a parser for the ethtool values in ethtool.py and ethernet.py - one instance ios more then enough!
2021-08-31ethernet: T3163: only change ring-buffer settings if requiredChristian Poessinger
Only update the RX/TX ring-buffer settings if they are different from the ones currently programmed to the hardware. There is no need to write the same value to the hardware again - this could cause traffic disruption on some NICs.

2021-08-30vyos.ifconfig: T3619: only inform user about real offload change for invalid ↵Christian Poessinger
option Commit 31169fa8 ("vyos.ifconfig: T3619: only set offloading options if supported by NIC") added a warning for the user if an offload option was about to change that was not possible at all (harware limit). Unfortunately the warning was even displayed if nothing was done at all. This got corrected.
2021-08-28vyos.ifconfig: T3619: only set offloading options if supported by NICChristian Poessinger
In the past we always told ethtool to change the offloading settings, even if this was not supported by the underlaying driver. This commit will only change the offloading options if they differ from the current state of the NIC and only if it's supported by the NIC. If the NIC does not support setting the offloading options, a message will be displayed for the user: vyos@vyos# set interfaces ethernet eth2 offload gro vyos@vyos# commit [ interfaces ethernet eth2 ] Adapter does not support changing large-receive-offload settings!

2021-02-28vif: T3349: use fixed ordering when enabling parent and child interfaceChristian Poessinger
When a VIF/VLAN interface is placed in admin down state but the lower interface, serving the vlan, is moved from admin down -> admin up, all its vlan interfaces will be placed in admin up state, too. This is bad as a VLAN interface will become admin up even if its specified as admin down after a reboot. To reproduce: set interfaces ethernet eth1 vif 20 disable set interfaces ethernet eth1 disable commit delete interfaces ethernet eth1 disable commit Now check the interface state and it returns UP,LOWER_UP 7: eth1.20@eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000 link/ether 00:50:56:b3:09:07 brd ff:ff:ff:ff:ff:ff inet6 fe80::250:56ff:feb3:907/64 scope link valid_lft forever preferred_lft forever
2021-02-28vyos.ifconfig: T1579: remove calls to vyos.ifconfig.Interface.get_config()Christian Poessinger
Interface.get_config() was always a pure helper which exposed a "per interface type" dictionary which was then fed by the caller to create interfaces by iproute2 which required additional options during creation time. Such interfaces had been: * tunnel * vxlan * geneve * macsec * wifi * macvlan / pseudo-ethernet The code was always duplicated to convert from the VyOS CLI based get_config_dict() to a dict which can be used to feed iproute2. This path has been removed and we now always feed in the entire dictionary retrieved by get_config_dict() or in the interfaces case, it's high-level wrapper get_interface_dict() to the interface we wan't to create. This also adds the - personally long awaited - possibility to get rid of the derived tunnel classes for e.g. GRE, IPIP, IPIP6 and so on.
2021-01-02ethernet: T3171: always use full CPU enable bitmask over computational maskChristian Poessinger
The Linux Kernel supports enabling more cores for RPS then we actually have. It does internal clipping/validation so there is no need for us to calculate the specifc enable mask we can simply throw "all -1" at the Kernel.

2020-09-19ifconfig: T2653: convert VLAN interfaces do discrete classChristian Poessinger
Instead of using an Adapter pattern to make interfaces VLAN-aware, create a derived class named VLANIf to represent a VLAN. This change was necessary to eliminate mixed code in Interfaces class which was VLAN - free, but recently gained some VLAN specific code for set_admin_state(). In addition this "autoresolves" the issue in T2894 as a bond vlan interface will no longer change the lower interface.

2020-07-25ifconfig: T2653: implement update() in derived classes for admin up/downChristian Poessinger
Every derived class must implement update() to set the interfaces admin up/down state. This is required to prevend extensive link flaps when e.g. reconfiguring bond interfaces.

The current VyOS CLI parser code written in Python contains a ton of duplicates which I can also hold myself accountable for - or maybe mainly me - depends on the angle of judge. While providing a new update() method in vyos.ifconfig.interfaces() this is extended for bridge interfaces in the derived bridge class. Signed-off-by: Christian Poessinger <christian@poessinger.com>

The current VyOS CLI parser code written in Python contains a ton of duplicates which I can also hold myself accountable for - or maybe mainly me - depends on the angle of judge. While providing a new update() method in vyos.ifconfig.interfaces() this is extended for ethernet based interfaces which also supports 802.1q, 802.1ad VLANs. This commit migrates the existing codebase for an ethernet based interfaces and implements the missing parts for VLANs. Adding or migrating other interfaces (e.g. bridge or bond) will become much easier as they must reuse the entire functionality - we now walk towards a single codepath.

Not all interface are capable of all features. Since commands are now checked for valid completion, ethtool command failure must be ignored.
2020-03-27ifconfig: T2158: never fail when setting flowcontrolThomas Mangin
the result of the commands used to setup the interface is now checked. flowcontrol can not always be set on all interfaces, and when/if it fails, it prevents the interace to come up. This is problematic as it may prevent the router to come up. Therefore flowcontrol must be allowed to fail gracefully/silently.
