net: get rid of SET_ETHTOOL_OPS

Dave Miller mentioned he'd like to see SET_ETHTOOL_OPS gone.
This does that.

Mostly done via coccinelle script:
@@
struct ethtool_ops *ops;
struct net_device *dev;
@@
-       SET_ETHTOOL_OPS(dev, ops);
+       dev->ethtool_ops = ops;

Compile tested only, but I'd seriously wonder if this broke anything.

None of these files are actually using any __init type directives
and hence don't need to include <linux/init.h>.   Most are just a

code getting copied from one driver to the next.

This covers everything under drivers/net except for wireless, which
has been submitted separately.

Instead of open-coding a PHY reset through the MII BMCR register, use
phy_init_hw() which does this for us and ensures that PHY device fixups
are also applied. We also remove a call to ethernet_phy_reset() which is
now unncessary since phy_attach() calls phy_attach_direct() which in
turns calls phy_init_hw().

__GFP_ZERO is an uncommon flag and perhaps is better
not used.  static inline dma_zalloc_coherent exists
so convert the uses of dma_alloc_coherent with __GFP_ZERO
to the more common kernel style with zalloc.

Remove memset from the static inline dma_zalloc_coherent
and add just one use of __GFP_ZERO instead.

Trivially reduces the size of the existing uses of
dma_zalloc_coherent.

Zero pointer in rx_skb or tx_skb is how respective *_deinit() functions find
out that a skb slot is unallocated. If *_init() functions unsuccessfully return
after the allocation (e.g. when subsequent dma_alloc_coherent() is not
successful), this would result in attempt to kfree() invalid pointers.

The change set of 4305b541, "[SK_BUFF]: Convert skb->end to sk_buff_data_t"
converted skb->end from pointer type to sk_buff_data_t.
The pointed value should be accessed via skb_end_pointer().

Since arm arch doesn't define NET_SKBUFF_DATA_USES_OFFSET,
skb->end is effectively pointer. So it doesn't cause a real problem.
But this patch is good for consistency.

Found by inspection. Compile tested only.

The flags argument of the phy_{attach,connect,connect_direct} functions
is then used to assign a struct phy_device dev_flags with its value.
All callers but the tg3 driver pass the flag 0, which results in the
underlying PHY drivers in drivers/net/phy/ not being able to actually
use any of the flags they would set in dev_flags. This patch gets rid of
the flags argument, and passes phydev->dev_flags to the internal PHY
library call phy_attach_direct() such that drivers which actually modify
a phy device dev_flags get the value preserved for use by the underlying
phy driver.

Adding casts of objects to the same type is unnecessary
and confusing for a human reader.

For example, this cast:

        int y;
        int *p = (int *)&y;

I used the coccinelle script below to find and remove these
unnecessary casts.  I manually removed the conversions this
script produces of casts with __force, __iomem and __user.

@@
type T;
T *p;

-       (T *)p

flush_scheduled_work() is on its way out.  This patch contains simple
conversions to replace flush_scheduled_work() usage with direct
cancels and flushes.

Directly cancel the used works on driver detach and flush them in
other cases.

The conversions are mostly straight forward and the only dangers are,

* Forgetting to cancel/flush one or more used works.

* Cancelling when a work should be flushed (ie. the work must be
  executed once scheduled whether the driver is detaching or not).

I've gone over the changes multiple times but it would be much
appreciated if you can review with the above points in mind.
