Note: The ‘Wait On Tx’ option is unchecked by default. For each port, an application
‘write’ will complete when the last data fragment is written to the TX FIFO but
before all the data has been physically transmitted. Each port has a 128 byte deep
TX FIFO and leaving ‘Wait On Tx’ un-checked may improve throughput.
However some applications implicitly assume that a ‘write’ will complete when
all data is physically transmitted. If such an application is to be used then check
the ‘Wait On Tx’ option.
