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.
