Hello James,

This patchset adds FC transport support to nvme fabrics. Adds both
initiator and target. The transport utilizes a lower-level api with
FC hbas to actually perform FC link traffic. The drivers are mostly
ignorant of the actual NVME transport implementation, and provide
hooks to send/receive FC-4
This patch updates the lpfc driver such that it ties into the NVME FC
transport to add host (initiator) support.
It currently is an unoptimized NVME implementation.
The patch:
-Replaces stubs so that the local FC port is registered with the
NVME FC transport as a "nvme local port"
-Replaces stub
nvme-fabrics: Add FC transport FC-NVME definitions:
- Formats for Cmd, Data, Rsp IUs
- Formats FC-4 LS definitions

Patch nvme-fabrics target code in prep for FC transport support:

- Add FC address family decoding

not merged before being brought
Patch nvme-fabrics host code in prep for FC transport support:
- Add the host_traddr field to allow specification of the host-port

- Revise nvmf_get_address() string to account for not all options being
present.
- Revise some of

Will be used by the nvme-fabrics FC transport in parsing options

Changing the case of a string (with or without copying it first) seems

This series introduces a family of generic string case conversion

the kernel. Right now, everybody seems to be implementing their own
copy of this functionality.

ata_mselect_*() would initialize a char array for storing a copy of
the current mode page. However, char could be signed char. In that
case, bytes larger than 127 would be converted to negative number.
For example, 0xff from def_control_mpage[] would become -1. This
prevented ata_m
Strange. I merely changed the two "char" to "u8". I wonder how the tab
became spaces. Anyway, sorry about that, resending soon.
