wifi: mt76: fix rx checksum offload on mt7615/mt7915/mt7921

2022-10-11T08:41:20Z

Checking the relevant rxd bits for the checksum information only indicates if the checksum verification was performed by the hardware and doesn't show actual checksum errors. Checksum errors are indicated in the info field of the DMA descriptor. Fix packets erroneously marked as CHECKSUM_UNNECESSARY by checking the extra bits as well. Those bits are only passed to the driver for MMIO devices at the moment, so limit checksum offload to those.

wifi: mt76: fix receiving LLC packets on mt7615/mt7915

2022-10-11T08:41:20Z

When 802.3 decap offload is enabled, the hardware indicates header translation failure, whenever either the LLC-SNAP header was not found, or a VLAN header with an unregcognized tag is present. In that case, the hardware inserts a 2-byte length fields after the MAC addresses. For VLAN packets, this tag needs to be removed. However, for 802.3 LLC packets, the length bytes should be preserved, since there is no separate ethertype field in the data. This fixes an issue where the length field was omitted for LLC frames, causing them to be malformed after hardware decap.

wifi: mt76: mt7915: do not check state before configuring implicit beamform

2022-09-15T11:21:39Z

Do not need to check running state before configuring implicit Tx beamform. It is okay to configure implicit Tx beamform in run time. Noted that the existing connected stations will be applied for new configuration only if they reconnected to the interface.

wifi: mt76: add PPDU based TxS support for WED device

2022-09-15T10:54:01Z

Given that there's no data coming from network stack for binding flows, hence driver counts and reports station's statistics directly through NL80211_STA_INFO_* based on active PPDU based TxS for offloading data. Apart from that, WA firmware and its offloading engine (SDO) have hardcoded "2" as PID, so we introduce MT_PACKET_ID_WED to differentiate WED reporting. Note that PPDU format TxS is mutually exclusive with MT_TXD5_TX_STATUS_HOST. Co-developed-by: Yi-Chia Hsieh Signed-off-by: Yi-Chia Hsieh Signed-off-by: Ryder Lee Signed-off-by: Felix Fietkau

wifi: mac80211: keep A-MSDU data in sta and per-link

2022-09-06T08:17:08Z

The A-MSDU data needs to be stored per-link and aggregated into a single value for the station. Add a new struct ieee_80211_sta_aggregates in order to store this data and a new function ieee80211_sta_recalc_aggregates to update the current data for the STA. Note that in the non MLO case the pointer in ieee80211_sta will directly reference the data in deflink.agg, which means that recalculation may be skipped in that case.
