usb: renesas_usbhs: set quirk_avoids_skb_reserve if USB-DMAC is used This patch sets the quirk_avoids_skb_reserve flag to improve performance of a network gadget driver (e.g. f_ncm.c) if USB-DMAC is used. For example (on r8a7795 board + f_ncm.c + iperf udp mode / receiving): - without this patch: 90.3 Mbits/sec - with this patch: 273 Mbits/sec Signed-off-by: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com> Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com>
