Subject: winverbs/ep: allow failed connections to be retried
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=7d4b66389e2d3bad56d68c46ddc50e8e55ba8258;p=~shefty%2Frdma-win.git

winverbs/ep: allow failed connections to be retried

Allow a user to retry a connection request if it fails.  Report a
'success' timeout value, rather than an error timeout, reset the
EP state, and allow the request to be retried from user space.
