    Subject[PATCH AUTOSEL 5.7 040/388] staging: wfx: fix output of rx_stats on big endian hosts
    Date
    From: Jérôme Pouiller <jerome.pouiller@silabs.com>

    [ Upstream commit a823d6ecd4904e1a6ffb12964de88fb0bb4802f6 ]

    The struct hif_rx_stats contains only little endian values. Thus, it is
    necessary to fix byte ordering before to use them.
