Brett Creeley 9e4ab4c29a ice: Add support for dynamic interrupt moderation
Currently there is no support for dynamic interrupt moderation. This
patch adds some initial code to support this. The following changes
were made:

1. Currently we are using multiple members to store the interrupt
   granularity (itr_gran_25/50/100/200). This is not necessary because
   we can query the device to determine what the interrupt granularity
   should be set to, done by a new function ice_get_itr_intrl_gran.

2. Added intrl to ice_q_vector structure to support interrupt rate
   limiting.

3. Added the function ice_intrl_usecs_to_reg for converting to a value
   in usecs that the device understands.

4. Added call to write to the GLINT_RATE register. Disable intrl by
   default for now.

5. Changed rx/tx_itr_setting to itr_setting because having both seems
   redundant because a ring is either Tx or Rx.

6. Initialize itr_setting for both Tx/Rx rings in ice_vsi_alloc_rings()

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.
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.
