Hi all,
I have dumped the Rx ring descriptor status when this happens. This is what
I found
"qprdc" ="Queue Packet Receive Drop Count">1602602</token>
"qrdh" ="Queue Receive Descriptor Head">1256</token>
qrdt" ="Queue Receive Descriptor Tail">1256</token>
qrdntc" ="Queue Receive Descriptor Next to Check">1257</token>
qrdlc" ="Queue Receive Descriptor Last Cleaned">1256</token>
I checked the status of the Rx Ring descriptos from 1257 onwards.
Descriptor 1257 status 0
Descriptor 1258 status 0
Descriptor 1259 status 0
...
...
...
Descriptor 1247 status 0
Descriptor 1248 status 0
Descriptor 1249 status -1073741725
Descriptor 1250 status -1073741725
Descriptor 1251 status -1073741725
Descriptor 1252 status -1073741725
Descriptor 1253 status -1073741725
Descriptor 1254 status -1073741725
Descriptor 1255 status -1073741725
Descriptor 1256 status 0
This means that the Application sees that the Rx_ring is empty, but actualy
Rx_ring is full and is in a bad state. Any idea what may be happening ?
Regards,
Kaushal
