[dpdk-dev] [PATCH v3] vmxnet3: fix Rx deadlock

Our use case is that we have an app that needs to keep mbufs around for a while. We've seen cases when calling vmxnet3_post_rx_bufs() from vmxet3_recv_pkts(), it might not succeed to add any mbufs to any RX descriptors (where it returns -err). Since there are no mbufs that the virtual hardware can
