Sagi Grimberg fb8658581a nvmet-tcp: fix uninitialized variable access
If we end up in nvmet_tcp_try_recv_one with a bogus state
queue receive state we will access result which is uninitialized.

Initialize restult to 0 which will be considered as if no data
was received by the tcp socket.

Sagi Grimberg 872d26a391 nvmet-tcp: add NVMe over TCP target driver
This patch implements the TCP transport driver for the NVMe over Fabrics
target stack. This allows exporting NVMe over Fabrics functionality over
good old TCP/IP.

The driver implements the TP 8000 of how nvme over fabrics capsules and
data are encapsulated in nvme-tcp pdus and exchaged on top of a TCP byte
stream. nvme-tcp header and data digest are supported as well.
