ravb: Add Gigabit Ethernet driver support
The DMAC and EMAC blocks of Gigabit Ethernet IP found on RZ/G2L SoC are
similar to the R-Car Ethernet AVB IP.
The Gigabit Ethernet IP consists of Ethernet controller (E-MAC), Internal
TCP/IP Offload Engine (TOE) and Dedicated Direct memory access controller
(DMAC).
With a few changes in the driver we can support both IPs.
Currently a runtime decision based on the chip type is used to distinguish
the HW differences between the SoC families.
This patch series is in preparation for supporting the RZ/G2L SoC by
replacing driver data chip type with struct ravb_hw_info by moving chip
type to it and also adding gstrings_stats, gstrings_size, net_hw_features,
net_features, aligned_tx, stats_len, max_rx_len variables to
it. This patch also adds the feature bit for {RX, TX} clock internal
delays and TX counters HW features found on R-Car Gen3 to struct
ravb_hw_info.
This patch series is based on net-next.
v2->v3:
* Removed num_gstat_queue variable from struct ravb_hw_info.
* started using unsigned int for num_tx_desc variable in struct ravb_private
* split the patch 'Add struct ravb_hw_info to driver data' into two
* Renamed skb_sz to max_rx_len and tx_drop_cntrs to tx_counters
and also updated the comments.
v1->v2:
* Replaced driver data chip type with struct ravb_hw_info
* Added gstrings_stats, gstrings_size, net_hw_features, net_features,
num_gstat_queue, num_tx_desc, stats_len, skb_sz to struct ravb_hw_info
* Added internal_delay and tx_drop_cntrs hw feature bit to struct ravb_hw_info
RFC->V1
* Incorporated feedback from Andrew, Sergei, Geert and Prabhakar

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.
