This code in cdc-ether.c, CDCEther_start_xmit()
2.5.x current but 2.4 seem wrong too:
// If we are told to transmit an ethernet frame that fits EXACTLY
// into an integer number of USB packets, we force it to send one
// more byte so the device will get a runt USB packet signalling the
// end of the ethernet frame
if ( (skb->len) ^ (ether_dev->data_ep_out_size) ) {
// It was not an exact multiple
// no need to add anything extra
count = skb->len;
} else {
// Add one to make it NOT an exact multiple
count = skb->len + 1;
}
Shoudn't it be skb->len % ether_dev->data_ep_out_size instead ?
Ben.
