FUNCTION WDA_TLI_FastHwFwdDataFrame
DESCRIPTION
For NON integrated SOC, this function is called by TL.
Fast path function to quickly forward a data frame if HAL determines BD
signature computed here matches the signature inside current VOSS packet.
If there is a match, HAL and TL fills in the swapped packet length into
BD header and DxE header, respectively. Otherwise, packet goes back to
normal (slow) path and a new BD signature would be tagged into BD in this
VOSS packet later by the WLANHAL_FillTxBd() function.
TODO For integrated SOC, this function does nothing yet. Pima SLM/HAL
should provide the equivelant functionality.
DEPENDENCIES
PARAMETERS
IN
pvosGCtx VOS context
vosDataBuff Ptr to VOSS packet
pMetaInfo For getting frame's TID
pStaInfo For checking STA type
OUT
pvosStatus returned status
puFastFwdOK Flag to indicate whether frame could be fast forwarded
RETURN VALUE
No return.
