Hi Aleksander and Daniele,

from looking at commit
https://portland.source.codeaurora.org/quic/qsdk/oss/lklm/gobinet/commit/GobiNet?id=6effcb052f0320bf32b44409f09643d548578e6b
("gobinet: Added support for QMAP with aggregation")
"WDS Bind Mux Port" seems to be used together with additional WDASetDataFormat
TLVs 0x12, ..., 0x17.

it seems that the firmware lacks support for this feature as only the setting
of TLV 0x11 is honored. Perhaps this feature is only available in firmwares
for newer Qualcomm chipset?
