📋 Description
In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7996: fix MLD ID in MAC TXD and HIF TXP
Problem: MCU command timeout while the firmware state is normal, and the firmware keeps showing the error log "ERROR!! NO PAUSE...".
Root cause: If the MLD_ID field in the TXD is neither the primary link id nor the secondary link id, it may lead to a firmware busy loop when the third link is in power saving mode.
Remap frames directed to a third link to the primary link wcid. Since TX status events and txfree completions carry the wcid the firmware saw, use the remapped wcid for packet id tracking and non-AQL packet accounting as well, while the frame keeps its original link context for addressing, band and OMAC selection.
