On leon, -this means that cache snooping must be configured in the -vhdl model and enabled by software. - -TX interrupts are not used and masked in the interrupt mask -register. - -For now, only 10 Mbit/s half-duplex is supported. -100 Mbit/s operations does not work reliably, the transmitter -locks up or skips frames. Seems to depend on the TX fifo -implementation in the opencores MAC. Send a mail to -jiri@gaisler.com if you know how to fix this. - -Tested only on leon, using the GR-PCI-XC2V board @ 40 MHz. -Output from ttcp receiving 1 Mbyte file: - ->>> ttcp -r -s -ttcp-r: buflen=8192, nbuf=2048, align=16384/0, port=5001 tcp -ttcp-r: socket -ttcp-r: accept from 192.168.0.2 -ttcp-r: 1145339 bytes in 1.18 real seconds = 947.88 KB/sec +++ -ttcp-r: 792 I/O calls, msec/call = 1.53, calls/sec = 671.19 -ttcp-r: 0.0user 1.1sys 0:01real 100% 0i+0d 0maxrss 0+0pf 0+0csw -************ MBUF STATISTICS ************ -mbufs:1024 clusters: 128 free: 112 -drops: 0 waits: 0 drains: 0 - free:1007 data:17 header:0 socket:0 - pcb:0 rtable:0 htable:0 atable:0 - soname:0 soopts:0 ftable:0 rights:0 - ifaddr:0 control:0 oobdata:0 - -************ INTERFACE STATISTICS ************ -***** open_eth1 ***** -Address:192.168.0.66 Broadcast Address:192.168.0.255 -Flags: Up Broadcast Running Simplex -Send queue limit:50 length:0 Dropped:0 - Rx Packets:796 Rx Interrupts:796 Length:0 - Bad CRC:0 Overrun:0 Miss:0 - Tx Interrupts:0 Deferred:0 Missed Hearbeat:0 - No Carrier:0 Retransmit Limit:0 Late Collision:0 - Underrun:0 Raw output wait:0 - -************ IP Statistics ************ - total packets received 795 - datagrams delivered to upper level 795 - total ip packets generated here 401 - -************ TCP Statistics ************ - connections accepted 1 - connections established 1 - conn. closed (includes drops) 1 - segs where we tried to get rtt 2 - times we succeeded 2 - delayed acks sent 4 - total packets sent 401 - ack-only packets sent 6 - window update-only packets sent 394 - control (SYN|FIN|RST) packets sent 1 - total packets received 795 - packets received in sequence 792 - bytes received in sequence 1145339 - rcvd ack packets 2 - bytes acked by rcvd acks 2 - times hdr predict ok for data pkts 791 - - |
