wifi: mt76: relicense to BSD-3-Clause-Clear

2025-11-24T13:37:54Z

MediaTek has asked to switch from the ISC license to BSD-3-Clause-Clear, in order to improve clarity and the legal integrity of the code. The BSD-3-Clause license includes the "no endorsement" clause, which is important for protecting the reputation of the original authors and contributors by preventing unauthorized use of their names for endorsement purposes. This clause is absent in the BSD-2-Clause license, which is more permissive but lacks this specific protection. This change also cleans up the license of some Kconfig/Makefile files, which were accidentally marked as GPL. The GPL 2.0 remains in use on mt76x0, as well as two source files in mt7615 for which the license situation still needs to be clarified.

wifi: mt76: fix tx packet loss when scanning on DBDC

2024-05-02T10:44:50Z

When queueing packets, only the MT76_RESET flag of the primary PHY is checked. If the primary PHY is scanning or changing channels, this can lead to packet loss for tx on the second PHY. Fix this by passing the phy to the .tx_queue_skb op and using it to check the correct flag. Signed-off-by: Felix Fietkau

wifi: mt76: testmode: add nla_policy for MT76_TM_ATTR_TX_LENGTH

2023-07-26T11:09:46Z

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

2022-09-15T10:53:56Z

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

2021-12-18T10:47:57Z

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. Signed-off-by: Shayne Chen Signed-off-by: Felix Fietkau

mt76: mt7921: introduce testmode support
