Currently when there is share buffer in the SSU(storage switching unit), the low waterline for RX private buffer is too low to keep the hardware running. Hardware may have processed all the packet stored in the private buffer of the low waterline before the new packet comes, because hardware only tell the peer send packet again when the private buffer is under the low waterline. So this patch only allocate RX private buffer if there is enough buffer according to hardware user manual. This patch also reserve some buffer for reusing when TC num is less than or equal to 2, and change PAUSE_TRANS_GAP & HCLGE_NON_DCB_ADDITIONAL_BUF according to hardware user manual.

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.
