wifi: mt76: testmode: add nla_policy for MT76_TM_ATTR_TX_LENGTH It seems that the nla_policy in mt76_tm_policy is missed for attribute MT76_TM_ATTR_TX_LENGTH. This patch adds the correct description to make sure the u32 val = nla_get_u32(tb[MT76_TM_ATTR_TX_LENGTH]); in function mt76_testmode_cmd() is safe and will not result in out-of-attribute read.

wifi: mt76: testmode: use random payload for tx packets Compared to fixed payload packets, random payload packets have better measured EVM under the same txpower. Our tests show EVM becomes at least 2-3 dB better in test cases with high rate and long tx length, which also aligns the testing results to proprietary driver.

mt76: testmode: add support to set MAC Add support to set SA/DA/BSSID in testmode. During mass production stage, some test scripts or test equipments need to set fixed addresses to detect or parse if a test is passed. Also, MAC setting is necessary for some tx/rx tests with rx filter, to make sure rx site only receives expected packets.

mt76: testmode: make tx queued limit adjustable 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>

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.
