NAME

net2280_set_fifo_mode - change allocation of fifo buffers

SYNOPSIS

"SYNOPSIS"

int net2280_set_fifo_mode (struct usb_gadget * gadget, int mode);

ARGUMENTS

gadget: access to the net2280 device that will be updated
mode: 0 for default, four 1kB buffers (ep-a through ep-d); 1 for two 2kB buffers (ep-a and ep-b only); 2 for one 2kB buffer (ep-a) and two 1kB ones (ep-b, ep-c).

DESCRIPTION

returns zero on success, else negative errno. when this succeeds, the contents of gadget->ep_list may have changed.

you may only call this function when endpoints a-d are all disabled. use it whenever extra hardware buffering can help performance, such as before enabling ``high bandwidth'' interrupt endpoints that use maxpacket bigger than 512 (when double buffering would otherwise be unavailable).
