Do I need to resend v4 patch? Or how can I to resolve this problem?

CAUTION! Use only if you are
Add a new 'snps,parkmode-disable-hs-quirk' DT quirk to dwc3 core for disable the high-speed parkmode. For some USB wifi devices, if enable this feature it will reduce the performance. Therefore, add an option for disabling HS park mode by device-tree. In Synopsys's dwc3 data book: In a few high speed devices when an IN request is sent within 900ns of the ACK of the previous packet, these devices send a NAK. When connected to these devices, if required, the software can disable the park mode if you see performance drop in your system. When park mode is disabled, pipelining of multiple packet is disabled and instead one packet at a time is requested by the scheduler. This allows up to 12 NAKs in a micro-frame and improves performance of these slow devices. Signed-off-by: Stanley Chang <stanley_chang@realtek.com> --- v2 to v3 change: 1.
