Add support to read module EEPROM for fbnic. Towards this, add required support to issue a new command to the firmware and to receive the response to the corresponding command. Create a local copy of the data in the completion struct before writing to ethtool_module_eeprom to avoid writing to data in case it is freed. Given that EEPROM pages are small, the overhead of additional copy is negligible. Do not block API with explicit checks since API has appropriate checks in place for length, offset, and page. Explicitly check bank, page, offset, and length in fbnic_fw_parse_qsfp_read_resp() to match EEPROM read responses to the correct request. This is important because if the driver times out waiting for an EEPROM read response, a subsequent read request with different values is susceptible to receiving an erroneous response (i.e., the response to the previous request).

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.
