There is a race condition when we go from iclass commands to mf command. Especially noticable when eload large files where we used to spam the device with usb packages.\ntry iclass eload, then mf eload, and you see the client hang. With this change we trigger a preload of the fpga image before we start uploading to the device. Current places I could trigger this bug was in eload and gsave. With this patch only the first call takes some time if fpga image must be loaded. The following goes fast.\n\n if you find that the client hangs when going between, this could be the root cause.
