Possible packet loss issue in recent net-next

In the last few pulls from net-next I am seeing an issue where sometimes a transfer would stall for about 30secs and then continue. I see this with simple commands like `rsh server uname -a` and ftp transfers. It happens with multiple drivers.

I have not done much digging into it yet, but just wanted to check if it's a known issue. I don't see this problem when testing with the torvalds tree.

Attached is a capture from the rsh session that fails. The "server" (190.1.15.5) is the system running net-next kernel.

Thanks,
Emil
