nvme-tcp: add basic support for the C2HTermReq PDU
[ Upstream commit 84e009042d0f3dfe91bec60bcd208ee3f866cbcd ]
Previously, the NVMe/TCP host driver did not handle the C2HTermReq PDU,
instead printing "unsupported pdu type (3)" when received. This patch adds
support for processing the C2HTermReq PDU, allowing the driver
to print the Fatal Error Status field.
Example of output:
nvme nvme4: Received C2HTermReq (FES = Invalid PDU Header Field)
