The pattern: entry = macb_tx_ring_wrap(bp, i); tx_skb = &queue->tx_skb[entry]; is the exact definition of: macb_tx_skb(queue, i); The pattern: entry = macb_tx_ring_wrap(bp, i); desc = macb_tx_desc(queue, entry); is redundant because macb_tx_desc() calls macb_tx_ring_wrap(). One explicit call to macb_tx_ring_wrap() is still required for checking if it is the last buffer (TX_WRAP case).

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 reStructuredText 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.
