Output of ixgbe_rx_offset() is based on ethtool's priv flag setting, which when changed, causes PF reset (disables napi, frees irqs, loads different Rx mem model, etc.). This means that within napi its result is constant and there is no reason to call it per each processed frame. Add new 'rx_offset' field to ixgbe_ring that is meant to hold the ixgbe_rx_offset() result and use it within ixgbe_clean_rx_irq(). Furthermore, use it within ixgbe_alloc_mapped_page(). Last but not least, un-inline the function of interest as it lives in .c file so let compiler do the decision about the inlining.

README
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.
