2021-01-26mt76: mt7615: mt7915: disable txpower sku when testmode enabledShayne Chen4-2/+6
When testmode can be enabled, the start() callback would already be called, causing that txpower sku feature isn't really disabled after testmode is enabled. This patch fix the issue. Signed-off-by: Shayne Chen <shayne.chen@mediatek.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>

2021-01-26mt76: testmode: add a new state for continuous txShayne Chen1-0/+2
Support to set a special tx state in testmode: continuous tx, which is used for sending tx without time gap. Note that continuous tx mode doesn't send real packets, instead, it's pure phy signal, and the waveform can be observed by instrument. Signed-off-by: Shayne Chen <shayne.chen@mediatek.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>

2021-01-26mt76: testmode: make tx queued limit adjustableShayne Chen3-2/+10
Originally, tx queued limit is set to 1000 to prevent from running out of tx token. If a new testmode tx is triggered while the previous one hasn't finished yet, we'll wait a period of time until tx_done equals to tx_queued. Normally, current queued limit can finish in 10 seconds. However, if ipg is configured to a larger value, less than 1000 packets can be done in the default timeout period, which may lead to a crash when a new testmode tx triggered. To deal with this, make tx queued limit dynamically adjusted according to ipg value. Signed-off-by: Shayne Chen <shayne.chen@mediatek.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2021-01-26mt76: testmode: add attributes for ipg related parametersShayne Chen3-0/+30

2021-01-26mt76: testmode: add support to set user-defined spe indexShayne Chen4-5/+19
Add spatial extension (spe) index as a configurable parameter in testmode. This is used for specifically configuring TX path, such as different WF TX priority, number of antennas and spatial streams. If spe_idx is not set, TX path depends on tx_antenna_mask; otherwise, both spe_idx and tx_antenna_mask are referenced to decide TX path.

2021-01-26mt76: mt7915: force ldpc for bw larger than 20MHz in testmodeShayne Chen1-1/+1

2021-01-26mt76: mt7915: drop zero-length packet to avoid Tx hangRyder Lee1-0/+3
