SCSI layer sends driver IOs with more s/g segments than driver can handle. This results in "Too many sg segments from dma_map_sg. Config 64, seg_cnt 219" error messages from the lpfc_scsi_prep_dma_buf_s3() routine. The was due to use the driver using individual templates for pport and vport, host reset enabled or not, nvme vs scsi, etc. In the end, there was a combination for a vport that didn't match the pport. Rather than enumerating more templates and more discretionary assignments, revert to a base template that is copied to a template specific to the pport/vport. Then, based on role, attributes and sli type, modify the fields that are different for that port. Added a log message to lpfc_create_port to validate values.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
