UDP packets work just fine. Below is a netio test of the card. The sun computer is the server for the test and another machine (which performs correctly for the same test with other machines) is a client. The results posted are as viewed from the client. results with netio -t option (TCP): Packet size 1k bytes: 10140 KByte/s Tx, 166 KByte/s Rx. Packet size 2k bytes: 11068 KByte/s Tx, 117 KByte/s Rx. Packet size 4k bytes: 11166 KByte/s Tx, 78516 Byte/s Rx. Packet size 8k bytes: 10271 KByte/s Tx, 67 KByte/s Rx. Packet size 16k bytes: 10328 KByte/s Tx, 61 KByte/s Rx. Packet size 32k bytes: 10329 KByte/s Tx, 76849 Byte/s Rx. Done. results with netio -u option (UDP): Packet size 1k bytes: 9388 KByte/s (0%) Tx, 10742 KByte/s (0%) Rx. Packet size 2k bytes: 10268 KByte/s (0%) Tx, 11257 KByte/s (0%) Rx. Packet size 4k bytes: 10541 KByte/s (0%) Tx, 11570 KByte/s (0%) Rx. Packet size 8k bytes: 10528 KByte/s (0%) Tx, 11581 KByte/s (0%) Rx. Packet size 16k bytes: 10542 KByte/s (0%) Tx, 11627 KByte/s (0%) Rx. Packet size 32k bytes: 10572 KByte/s (0%) Tx, 11642 KByte/s (0%) Rx. Done. As can be seen above, the LAN is 10MB/s capable, while the card is barely performing over a few hundred kbytes/s. Steps to reproduce: not working as-is. The problem has been observed by atleast one other person (http://forums.gentoo.org/viewtopic-t-500365-highlight-.html?sid=121fb7b0c83e17e7e18a5bce20a2971d) Please look into it. thanks Saurabh ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
