Subject: iw_cxgb4: drop listen destroy replies if no ep found
From: Steve Wise <swise@xxxxxxxxxxxxxxxxxxxxx>
commit 3c8415cc7aff467faba25841fb859660ac14a04e upstream.
If the thread waiting for a CLOSE_LISTSRV_RPL times out and bails,
then we need to handle a subsequent CPL if it arrives and the stid has
been released. In this case silently drop it.
