There are cases under heavy load (at least for HPE CXI provider) that trying to post a receive buffer can return -FI_EAGAIN. This PR uses the OFI_RETRY_UNTIL_DONE macro to try reposting receive buffer in the event -FI_EAGAIN is returned from the fi_recv call. Signed-off-by: Howard Pritchard <hppritcha@gmail.com>
