stmmac: rework the code to get the Synopsys ID (v3)
The Synopsys ID is now passed from the MAC core
to the main. This info will be used for managing
the HW cap register (supported in the new GMAC
generations).

This patch adds the MMC management counters support.
MMC module is an extension of the register address
space and all the hardware counters can be accessed
via ethtoo -S ethX.
Note that, the MMC interrupts remain masked and the logic
to handle this kind of interrupt will be added later (if
actually useful).

stmmac: support wake up irq from external sources (v3)
On some platforms e.g. SPEAr the wake up irq differs from the
GMAC interrupt source.
With this patch an external wake up irq can be passed through the
platform code and named as "eth_wake_irq".
In case the wake up interrupt is not passed from the platform
so the driver will continue to use the mac irq (ndev->irq)

net: linkwatch: allow vlans to get carrier changes faster
There is a time-lag of IFF_RUNNING flag consistency between vlan and
real devices when the real devices are in problem such as link or cable
broken.
This leads to a degradation of Availability such as a delay of failover
in HA systems using vlan since the detection of the problem at real
device is delayed.
We can avoid the linkwatch delay (~1 sec) for devices linked to another
ones, since delay is already done for the realdev.

Based on finds for Stephen Rothwell, where current defconfig's
enable a ethernet driver and it is not compiled due to the newly
added NET_VENDOR_* component of Kconfig.
This patch enables all the "new" Kconfig options so that current
defconfig's will continue to compile the expected drivers. In
addition, by enabling all the new Kconfig options does not add
any un-expected options.

e1000: save skb counts in TX to avoid cache misses
Virtual Machines with emulated e1000 network adapter running on Parallels'
server were seeing kernel panics due to the e1000 driver dereferencing an
unexpected NULL pointer retrieved from buffer_info->skb.
The problem has been addressed for the e1000e driver, but not for the e1000.
Since the two drivers share similar code in the affected area, a port of the
following e1000e driver commit solves the issue for the e1000 driver:
e1000e: save skb counts in TX to avoid cache misses
In e1000_tx_map, precompute number of segements and bytecounts which
are derived from fields in skb; these are stored in buffer_info. When
cleaning tx in e1000_clean_tx_irq use the values in the associated
buffer_info for statistics counting, this eliminates cache misses
on skb fields.
