    Subject[PATCH 4.19 082/346] USB: gadget: f_rndis: fix bitrate for SuperSpeed and above
    Date
    From: Will McVicker <willmcvicker@google.com>

    commit b00f444f9add39b64d1943fa75538a1ebd54a290 upstream.

    Align the SuperSpeed Plus bitrate for f_rndis to match f_ncm's ncm_bitrate
    defined by commit 1650113888fe ("usb: gadget: f_ncm: add SuperSpeed descriptors
    for CDC NCM").
