FUNCTION WDA_DS_BuildTxPacketInfo
DESCRIPTION
Build TX meta info for integrated SOC.
Same function calls HAL for reserve BD header space into VOS packet and
HAL function to fill it.
DEPENDENCIES
PARAMETERS
IN

pvDestMacAddr destination MAC address ponter
ucDisableFrmXtl Is frame xtl disabled?
ucQosEnabled Is QoS enabled?
ucWDSEnabled Is WDS enabled?
extraHeadSpace Extra head bytes. If it's not 0 due to 4 bytes align
of BD header.
typeSubtype typeSubtype from MAC header or TX metainfo/BD
pAddr2 address 2
uTid tid
