The Intel service layer driver has defined error codes for the
specific services, which started from FPGA configuration then RSU
(Remote Status Update).
Intel service layer driver should define the standard error codes
rather than keep adding more error codes for the new services.
The standard error codes will be used by all the clients of Intel service
layer driver.
Replace FPGA and RSU specific error codes with Intel service layer’s
Common error codes.

This patch replaces function module_init() with subsys_initcall().
It is needed to ensure that the core module of the driver is
initialized before a component tries to register with the core. This
leads to a NULL pointer dereference if the driver is configured as

Commit ed830385a2 ("scsi: ibmvfc: Avoid loss of all paths during SVC node
reboot") introduced a regression where when the client resets or re-enables
its CRQ with the hypervisor there is a chance that if the server side
doesn't issue its INIT handshake quick enough the client can issue an
Implicit Logout prior to doing an NPIV Login. The server treats this
scenario as a protocol violation and closes the CRQ on its end forcing the
client through a reset that gets the client host state and next host action
out of agreement leading to a BUG assert.

syzbot managed to set up sfq so that q->scaled_quantum was zero,
triggering an infinite loop in sfq_dequeue()
More generally, we must only accept quantum between 1 and 2^18 - 7,
meaning scaled_quantum must be in [1, 0x7FFF] range.
Otherwise, we also could have a loop in sfq_dequeue()

Fix the logic that sets the enable/disable flag for the source MAC
filter according to firmware spec 1.7.1.
In the original firmware spec. before 1.7.1, the VF spoof check flags
were not latched after making the HWRM_FUNC_CFG call, so there was a
need to keep the func_flags so that subsequent calls would perserve
the VF spoof check setting. A change was made in the 1.7.1 spec
so that the flags became latched. So we now set or clear the anti-
spoof setting directly without retrieving the old settings in the
stored vf->func_flags which are no longer valid. We also remove the
unneeded vf->func_flags.
