From: Jérôme Pouiller <jerome.pouil...@silabs.com>
The struct hif_req_edca_queue_params comes from hardware API. It is not
intended to be manipulated in upper layers of the driver.
So, this patch:
1. relocate the handling of this struct in hif_set_edca_queue_params()
(the low level function)
2. replace it in wfx_vif by the mac80211 equivalent: struct
ieee80211_tx_queue_params
