hi David:

Is it only specific to iso scheduling or bulk also need to take care?
from your kind explanation, the trb buffer for Bulk also need to take
care crossing 64k physical boundary.
But i don't find it for bulk transfer.
Below is excerpted from xhci_queue_bulk_tx
while (running_total < urb->transfer_buffer_length) {
num_trbs++;
running_total += TRB_MAX_BUFF_SIZE;
}
appreciate your kind help,
