Vitaly Kuzmichev 98fae9707f USB-CDC: Prevent rx_req being enqueued twice ... After gadget reinitializaton (after tftp has been done once) packet_received may become equal to 1 due to nuking OUT_EP while disabling it in eth_reset_config. rx_submit called from usb_eth_init queues rx_req first time. But the first call of usb_eth_recv from NetLoop queues rx_req again due to packet_received = 1. The following flow shows the path of functions calls when this happens: net/net.c:NetLoop | +-net/eth.c:eth_init | ether.c:usb_eth_init | | | +-udc_driver:usb_gadget_handle_interrupts | | udc_driver:... | | ether.c:eth_setup | | ether.c:eth_set_config | | ether.c:eth_reset_config | | udc_driver:usb_ep_disable | | udc_driver:nuke | | ether.c:rx_complete | | ether.c: packet_received = 1; | | | +-ether.c:rx_submit | udc_driver:usb_ep_queue --- The first time when rx_req is queued | +-net/eth.c:eth_rx ether.c:usb_eth_recv | +-udc_driver:usb_gadget_handle_interrupts | udc_driver:... --- no interrupts, returning +-ether.c: if (packet_received) { ... ether.c:rx_submit udc_driver:usb_ep_queue --- The second time!
