[ Upstream commit6e1cdedcf0] NETDEV_TX_BUSY really should only be used by drivers that call netif_tx_stop_queue() at the wrong moment. If dma_map_single() is failed to map tx DMA buffer, it might trigger an infinite loop. This patch use NETDEV_TX_OK instead of NETDEV_TX_BUSY, and change printk to pr_err_ratelimited.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
