Now that we use the cumulative consumer index scheme for TX completion, we don't need to have one TX completion per TX packet in the xmit_more code path. Set the TX_BD_FLAGS_NO_CMPL flag if xmit_more is true. Fallback to one interrupt per packet if the ring is filled beyond bp->tx_wake_thresh. Also, move the wmb() to bnxt_txr_db_kick(). When xmit_more is true, we'll skip the bnxt_txr_db_kick() call and there is no need to call wmb() to sync. the TX BD data.

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.
