Currently, the driver is able to query the device's specifications, which includes the maximum BD number of non TSO packet, so replace macro HNS3_MAX_NON_TSO_BD_NUM with the queried value, and rewrite macro HNS3_MAX_NON_TSO_SIZE whose value depends on the the maximum BD number of non TSO packet. Also, add a new parameter max_non_tso_bd_num to function hns3_tx_bd_num() and hns3_skb_need_linearized(), then they can get the maximum BD number of non TSO packet from the caller instead of calculating by themself, The note of hns3_skb_need_linearized() should be update as well.

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.
