[Openib-windows] wsd over mt23108 data corruption issue (x64)

[Guy Corem]

Hi Fab,

When running the transmitter side with the debug flag, the problem still
occurred.
When running the receiver side with the debug flag, due to errors, only
part of the file are being received (different sizes, between 10MB and
20MB, less than the 32MB threshold).

Do you want me to send you DebugView logs of the transmitter or the
receiver?

Guy

Large transfers don't really involve the sender beyond advertising the
buffer to the remote side - the data is actually transfered by the
receiver using RDMA Read.  Does the problem occur with the debug
provider?  If so, can you capture debug output with the environment
variable IBWSD_DBG=0x88001000 (assuming it still occurs with the debug
output)?  You'll want to do this by running the app under WinDbg,
rather than sending the output to the kernel debugger (otherwise the
impact on timings is likely going to be too great).

Thanks,
