[ofw] svn.2079 checkins and hung dapltest.exe server process

[Smith, Stan]

Further testing of hung windows process has shown the problem in ttcp.exe (sender) when an IPoIB IPv4 remote address is used.

A debug version of ibbus.sys did not fire any asserts w.r.t. reference counting or anything else.

Attaching windbg to the hung process shows it's waiting in the NT kernel - somewhat supports the ref counting theory. More attention needed here as I did not have current kernel symbols.

The salient point: this is not 'just' a dapltest.exe issue.

Cause-n-effect point out that before svn.2079 daptest.exe worked fine, afterwards problems.

Stan.
