Support more txq_alloc command types by moving the command declaration to the gen specific area. While at it, move some of the code segments to a common place for re-use. Signed-off-by:

As with the non-offloaded rs case, during assoc on the ap side the phy context is set to 20MHz until authorization of a client that supports wider channel-widths. Support this by sending the initial tlc_config_cmd with max supported channel width of 20MHz until authorization succeeds. Fixes: 6b7a5aea ("iwlwifi: mvm: always init rs with 20mhz bandwidth rates") Signed-off-by:

Probe responses were sent to the multicast station while they should be routed to the broadcast station. This has no negative effect since the frame was still routed to the right queue, but it looked very fishy to send a frame to a (queue, station) tuple where 'queue' is not mapped to 'station'. Fixes: 7c305de2 ("iwlwifi: mvm: Direct multicast frames to the correct station") Signed-off-by:

If the bandwidth is only 20 MHz, then the second channel doesn't exist, but the hardware reports the CRC was OK. Suppress the data of the second channel in the HE radiotap in this case, by marking it as not known. Signed-off-by:

I evidently completely confused "number of LTF symbols" and "LTF size". Radiotap was reporting the former, while I thought it was the latter, and we really need both. Add the LTF symbol size into the newly defined field in radiotap. Signed-off-by:

Implement the extended HE-MU info type decoding to show the HE-SIG-B common contents in the HE-MU radiotap field. The DW4 data is partially overwritten by the hardware in all cases, so only the higher 16 bits can be used. To be able to use it for the HE SIG-B common data anyway, move the bits around in the following way: SIG-B common 0: DW 4 -> DW 7 SIG-B common 1: DW 7 -> DW 8 SIG-B common 2: DW 8 -> DW 4 (upper half) Signed-off-by:

We offloaded all the RX configuration of init to firmware. However, the configuration of interrupt coalescing was left hanging - it wasn't offloaded nor was it written by host. This write to the CSR is allowed in gen2, so the host can do it. Without it we have various issues with RX fullness. Signed-off-by:

The parameter that indicated whether the LQ command should be sent as sync or async was removed, causing the LQ command to be sent as sync from interrupt context (e.g. from the RX path). This resulted in a kernel warning: "scheduling while atomic" and failing to send the LQ command, which ultimately leads to a queue hang. Fix it by adding back the required parameter to send the command as sync only when it is allowed. Fixes: d94c5a82 ("iwlwifi: mvm: open BA session only when sta is authorized") Signed-off-by:

When we receive TX response, we may release a few packets due to a hole that was closed in the transmission window. However, if that frame failed, we will mark all the released frames as failed and will send multiple BARs. This affects statistics badly, and cause unnecessary frames transmission. Instead, mark all the following packets as success, with the desired result of sending a bar for the failed frame only. Signed-off-by:

There is a bug in FW where the sequence control may be incorrect, and the driver overrides it with the value of the ieee80211 header. However, in BAR there is no sequence control in the header, which result with arbitrary sequence. This access to an unknown location is bad and it makes the logs very confusing - so fix it.

When the NIC is disconnected, we just can't do anything besides seeking for help from the bus driver. Dumping the device's memory is not necessary and just bloats the logs with unusable data. Moreover, asking mac80211 to restart the hardware is also useless. Bypass all this. Also, use the STATUS_TRANS_DEAD status bit instead of a bool inside the transport layer. The advantage of this is that now, the transport and the op_mode can know what is the situation and bypass the useless recovery steps mentioned above. Signed-off-by:

There's no point in warning here, the user will just get an error back to the debugfs file write, and warning just makes it seem like there's an internal consistency problem when in reality the user just happened to hit this at a bad time.

Every rx mpdu cmd is built from cmd_hdr | 80211_hdr. The problem is that the size of cmd_hdr changes with API changes and we don't know where the 80211_hdr starts. By adding the size of cmd_hdr dynamically, we can ensure that we always know how to parse mpdu frames, without dependending on the API changes. Signed-off-by:

A probe response built by a P2P GO should contain: 1. CSA/eCSA IE when relevant 2. If the corresponding probe request had P2P IE, then need to add P2P IE with NOA attributes. However, the NOA attributes and the updated channel switch counter are known only to the FW. The solution is that FW will send a notification with the relevant probe response data and the driver will save it and update the probe response accordingly. Signed-off-by:
