For HNAE3_DEVICE_VERSION_V3, a maximum of 1281 interrupt resources are supported. To utilize these new resources, extend the corresponding field or variable to 16bit type, and remove the restriction of NIC client that only use a maximum of 65 interrupt vectors. In addition, the I/O address of the extended interrupt resources are different, so an extra handler is needed. Currently, the total number of interrupts is the sum of RoCE's number and RoCE's offset (RoCE is in front of NIC), since the number of both NIC and RoCE are same. For readability, rewrite the corresponding field of the command, rename the RoCE's offset field as the number of NIC interrupts, then the total number of interrupts is sum of the number of RoCE and NIC, and replace vport->back with hdev in hclge_init_roce_base_info() for simplifying the code.

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.
