Check for ethtool_ops structures that are only stored in the ethtool_ops
field of a net_device structure or passed as the second argument to
netdev_set_default_ethtool_ops. These contexts are declared const, so
ethtool_ops structures that have these properties can be declared as const
also.
The semantic patch that makes this change is as follows:

There are two generics functions phy_ethtool_{get|set}_link_ksettings,
so we can use them instead of defining the same code in the driver.

The private structure contain a pointer to phydev, but the structure
net_device already contain such pointer. So we can remove the pointer
phy in the private structure, and update the driver to use the
one contained in struct net_device.

Replace all trans_start updates with netif_trans_update helper.
change was done via spatch:
struct net_device *d;
@@
- d->trans_start = jiffies
+ netif_trans_update(d)
Compile tested only.

BITS_RX_EN is an 'unsigned long' constant, so the ones complement of that
has bits set that do not fit into a 32-bit variable on 64-bit architectures,
which causes a harmless gcc warning:
drivers/net/ethernet/hisilicon/hix5hd2_gmac.c: In function 'hix5hd2_port_disable':
drivers/net/ethernet/hisilicon/hix5hd2_gmac.c:374:2: warning: large integer implicitly truncated to unsigned type [-Woverflow]
writel_relaxed(~(BITS_RX_EN | BITS_TX_EN), priv->base + PORT_EN);
This adds a cast to (u32) to tell gcc that the code is indeed fine.

None of those drivers uses last_rx for its own needs.
See 4dc89133f49b8cfd77ba7e83f5960aed63aaa99e ("net: add a comment on
netdev->last_rx") for reference.

Add support for the hix5hd2 XGMAC 1Gb ethernet device.
The controller requires two queues for tx and two queues for rx.
Controller fetch buffer from free queue and then push to used queue.
Diver should prepare free queue and free buffer from used queue.
