* HTT tx MSDU descriptor
*
* The HTT tx MSDU descriptor is created by the host HTT SW for each
* tx MSDU. The HTT tx MSDU descriptor contains the information that
* the target firmware needs for the FW's tx processing, particularly
* for creating the HW msdu descriptor.
* The same HTT tx descriptor is used for HL and LL systems, though
* a few fields within the tx descriptor are used only by LL or
* only by HL.
* The HTT tx descriptor is defined in two manners: by a struct with
* bitfields, and by a series of [dword offset, bit mask, bit shift]
* definitions.
* The target should use the struct def, for simplicitly and clarity,
* but the host shall use the bit-mast + bit-shift defs, to be endian-
* neutral. Specifically, the host shall use the get/set macros built
* around the mask + shift defs.
