2020-11-12qtnfmac: switch to core handling of rx/tx byte/packet countersHeiner Kallweit
Use netdev->tstats instead of a member of qtnf_vif for storing a pointer to the per-cpu counters. This allows us to use core functionality for statistics handling. The driver sets netdev->needs_free_netdev, therefore freeing the per-cpu counters at the right point in time is a little bit tricky. Best option seems to be to use the ndo_init/ndo_uninit callbacks.

2020-03-12qtnfmac: assign each wiphy to its own virtual platform deviceSergey Matyukevich
Quantenna Pearl device exposes multiple (up to 3) radio interfaces under single PCIe function. So far all the wiphy devices were attached to the same pcie device. As a result, all different wireless network devices were reported under the same sysfs directory for pcie device, e.g.: $ ls /sys/class/net/wlan0/device/net/ wlan0 wlan1 It turns out that such behavior may confuse various users of wireless subsystem. For instance, it turned out to be the case for: - Linux init systems, e.g. for renaming based on parent device - OpenWRT configuration scripts Suggested solution is to add an intermediate virtual platform device for each radio interface.

2020-02-12qtnfmac: implement extendable channel survey dumpIgor Mitsyanko
Switch to extendable implementation of channel survey dump to make sure that any new channel statistics can be added in the future without any backwards compatibility issues. For this purpose use a separate variable length bitmap to pass the list of valid statistics in firmware response. Besides, switch to using channel frequency instead of IEEE channel number to prepare for adding support of 6GHz band.

2020-02-12qtnfmac: use MAJOR.MINOR format for firmware protocolIgor Mitsyanko
Use MAJOR.MINOR format for QLink firmware protocol. MAJOR part is incremented when backward compatibility is broken. Normally this part should not be incremented unless there is a good reason for that. MINOR part is incremented each time when new features are added to qlink.h, e.g. new TLVs, events, commands. These changes should not break backward compatibility. For instance, older firmware versions may not be able to parse new flags or send new types of events, but this does not impact normal system operations. As part of initialization sequence, driver requests protocol version from firmware and refuses to start in case there is a mismatch in MAJOR part of the version.

2020-01-26qtnfmac: add module param to configure DFS offloadSergey Matyukevich
Firmware may support DFS offload. However the final decision on whether to use it or not should be up to the user. So even if firmware supports DFS offload, it should be enabled only if user explicitly requests it. For this purpose introduce kernel param dfs_offload which is disabled by default.

2019-11-20qtnfmac: track broadcast domain of each interfaceIgor Mitsyanko
If firmware reports that it supports hardware switch capabilities, driver needs to track and notify device whenever broadcast domain of a particular network device changes (ie. whenever it's upper master device changes). Firmware needs a unique ID to tell broadcast domains from each other which is an opaque number otherwise. For that purpose we can use netspace:ifidx pair to uniquely identify each broadcast domain: - if netdev is not part of a bridge, then use it's own ifidx as a broadcast domain ID - if netdev is part of a bridge, then use bridge netdev ifidx as broadcast domain ID Firmware makes sure that packets are only forwarded between interfaces marked with the same broadcast domain ID.

Send EAPOL frames via control path so they can be treated in a different way rather than normal data frames. In this case EAPOLs are sent with higher priority and with disabled aggregation and encryption. Besides, all devices benefit from sending EAPOL frames via high priority path, so move the functionality from chip specific to common code.

2019-04-26qtnfmac: modify debugfs to support multiple cardsSergey Matyukevich
This patch modifies location of debugfs entries and their naming conventions to support multiple wireless cards on pcie host. Selected approach is to use separate directories for different wireless cards in top-level qtnfmac debugfs directory.

2019-04-04qtnfmac: allow each MAC to specify its own regulatory rulesIgor Mitsyanko

2018-01-24qtnfmac: modify supported interface combinationsSergey Matyukevich
Update existing code handling configuration of supported interface combinations. Current implementation is not complete since it does not report multiple interface combinations which are incompatible with each other. Instead current implementation packs all the supported combinations into single entry. In fact currently qsr10g wireless card supports the following two distinct interface combinations: 1. STA/repeater: 1 STA and/or 1 AP { { .max = 1, .types = NL80211_IFTYPE_AP}, { .max = 1, .types = NL80211_IFTYPE_STA}, } 2. AP/mBSS { { .max = 8, .types = NL80211_IFTYPE_AP}, } The list of supported configuration is reported by firmware during wireless card bring-up. Communication protocol between firmware and host has been updated accordingly in order to accommodate passing multiple interface combination entries.

2017-10-30qtnfmac: modify full Tx queue recoverySergey Matyukevich
Current recovery approach is to wake s/w Tx queues for skb->dev netdevice. However this approach doesn't cover the case when h/w queue is full of packets from a single wireless interface. Suppose xmit attempt from the second wireless interface fails due to failed reclaim. Then the second interface will not have a chance to recover even if subsequent reclaims succeed.
