In current fcoe utils, both fcoemon and fcoeadm could write to /sys/class/..
files by calling "create"/"destroy"/"reset" commands. Fcoemon has no way to
manage those files after startup. Fcoeadm bypasses fcoemon and accesses
those files.
So this patch create socket interface between fcoemon and fcoeadm. Fcoemon as
server provided an IPC interface for client applications(fcoeadm) to set
create/reset/destroy device interface. fcoeadm doesn't write to those files
anymore, instead, it connects to the client interface of
fcoemon to perform those operations.
The detail changes are as following:
a. Create new files fcoe_clif.h/c as a library used by fcoemon and
fcoeadm. Clif stands for client interface. Change Makefile.am for new files
fcoe_clif.h/c
b. In fcoemon.c/h, create socket interface and resiger receive function using
sa_loop_select. The code has merged with fcoemon redesign. In fcoe_port
struct, add a new member as socket reply information. Fcoemon will save the
socket reply info and wait to reply to fcoeadm at the end of select loop
after the "action".
c. In fcoeadm.c/h, remove the code of access sysfs files, create socket to
connect to fcoemon, send request, parse and print out the response;
d. in fcoeplumb, remove "create", "delete" and "reset" commands.
