wfx_tx_get_tid() was used as a wrapper around ieee80211_get_tid(). It did sometime return WFX_MAX_TID to ask to upper layers to not include the frame in "buffered" counter. The objective of this behavior is not clear, but tests has shown that wfx_tx_get_tid() can be replaced by ieee80211_get_tid() without any regressions. BTW, it is not necessary to save the tid in tx_rpiv since it can be retrieved from the 802.11 header.
