Transmit Packet Burst Length
This bit field is a coding for the maximum burst length on PCI bus, when
data management unit fetches transmit packets. Please refer to
4 "Threshold Codings" on Page 155
code and maximum burst length.
Minimum Frame Length
Only valid for those channel which have bit CSPEC_MODE_REC.SFDE
set. MINFL sets the minimum frame length in bytes (payload bytes and
CRC bytes) for frames which will be forwarded to system memory. If
enabled the receive buffer will drop frames which are smaller or equal to
the programmed value MINFL to avoid wasting of PCI bandwidth in case
of error conditions. The small frame check is disabled, if MINFL is set to
zero.
Note: Since the receive packets will be dropped inside the receive
0
H
buffer, the receive packet threshold CSPEC_BUFFER.RTC has
to be greater than MINFL/4 in order to work properly.
