    iwlwifi: mvm: support bss dynamic alloc/dealloc of queues · 24afba76
    Liad Kaufman authored
    "DQA" is shorthand for "dynamic queue allocation". This
    enables on-demand allocation of queues per RA/TID rather than
    statically allocating per vif, thus allowing a potential
    benefit of various factors.
    
    Please refer to the DOC section this patch adds to sta.h to
    see a more in-depth explanation of this feature.
    
    There are many things to take into consideration when working
    in DQA mode, and this patch is only one in a series. Note that
    default operation mode is non-DQA mode, unless the FW
    indicates that it supports DQA mode.
    
    This patch enables support of DQA for a station connected to
    an AP, and works in a non-aggregated mode.
    
    When a frame for an unused RA/TID arrives at the driver, it
    isn't TXed immediately, but deferred first until a suitable
    queue is first allocated for it, and then TXed by a worker
    that both allocates the queues and TXes deferred traffic.
    
    When a STA is removed, its queues goes back into the queue
    pools for reuse as needed.
