Add support for configuring secondary unicast addresses. Unicast
addresses take precendece over multicast addresses when filling
the exact address filters to avoid going to promiscous mode.
When more unicast addresses are present than filter slots,
unicast filtering is disabled and all slots can be used for
multicast addresses.

On the systems that have cache incoherent DMA, including ARM, there
is a race condition between software allocating a new receive buffer
and hardware writing into a buffer. The two race on touching the last
Receive Frame Descriptor (RFD). It has its el-bit set and its next
link equal to 0. When hardware encounters this buffer it attempts to
write data to it and then update Status Word bits and Actual Count in
the RFD. At the same time software may try to clear the el-bit and
set the link address to a new buffer.
Since the entire RFD is once cache-line, the two write operations can
collide. This can lead to the receive unit stalling or interpreting
random memory as its receive area.
The fix is to set the el-bit on and the size to 0 on the next to last
buffer in the chain. When the hardware encounters this buffer it stops
and does not write to it at all. The hardware issues an RNR interrupt
with the receive unit in the No Resources state. Software can write
to the tail of the list because it knows hardware will stop on the
previous descriptor that was marked as the end of list.
Once it has a new next to last buffer prepared, it can clear the el-bit
and set the size on the previous one. The race on this buffer is safe
since the link already points to a valid next buffer and the software
can handle the race setting the size (assuming aligned 16 bit writes
are atomic with respect to the DMA read). If the hardware sees the
el-bit cleared without the size set, it will move on to the next buffer
and skip this one. If it sees the size set but the el-bit still set,
it will complete that buffer and then RNR interrupt and wait.

To quote one of my favorite contemporary author:
[include/linux/sockios.h]
* THESE IOCTLS ARE _DEPRECATED_ AND WILL DISAPPEAR IN 2.5.X -DaveM
*/
#define SIOCDEVPRIVATE 0x89F0 /* to 89FF */
[...]
Gentoo's snmpd trips up over this code when trying to figure if the driver
supports the non-SIOCDEVPRIVATE API or not. One can argue over its choice
of heuristic but there no reason to make ioctl more ugly than needed.

While cleaning up the internal API focussing on Fiber and CX4 code
we found that I had broken the copper PHY initialization code. This
patch restores the PHY-specific code. This is mostly uninteresting
since no copper PHY boards are yet available. The changes have been
tested against Fiber only as I do not even have copper PHY versions
of 82598 macs.
This change actually cleans up the API code a bit more and we
lose some initialization code. A few PHY link detection helper
lines of code have been snuck into this patch, as well as a
read flush where it was suspected that this might cause issues.

e1000e will from now on support the PCI-Express adapters that
previously were supported by e1000. This support means better
performance and easier debugging from now on for both the old
PCI-X/PCI hardware and PCI-Express adapters.
This patch also moves 3 recently merged device IDs over to e1000e
that are identical to quad-port versions of already existing
dual port versions. With this last bit every former e1000 pci-e
device should work now with e1000e.
Here is a brief list of which gigabit driver to use with which
adapter:
e1000:
82540 -> 82547
e1000e:
82571 -> 82573
ich8, ich9 (82562 or 82566)
es2lan (80003eslan)
igb: (not yet merged, only available from e1000.sf.net)
82575

L1 ASPM link (pci-e link power savings) has significant benefits
(~1W savings when link is active) but unfortunately does not work
correctly on any of the chipsets that have 82573 on mobile platforms
which causes various nuisances:
- eeprom reads return garbage information leading to bad eeprom
checksums
- long ping times (up to 2 seconds)
- complete system hangs (freeze/lockup)
A lot of T60 owners have been plagued by this, but other mobile
solutions also suffer from these symptoms.
Disabling L1 ASPM before we activate the PCI-E link fixes all of
these issues at the cost of some power consumption.
Remove a workaround RDTR adjustment that is no longer needed with
this new one.

This converts uses of ARRAY_SIZE(), and while at it also kills
unreachable code as far as I can say. I can't tell what was the author
trying to do with the following check. First we have:
PNMI_STATIC const SK_PNMI_STATADDR
StatAddr[SK_PNMI_MAX_IDX][SK_PNMI_MAC_TYPES];
and then a check goes like this:
if (SK_PNMI_MAX_IDX !=
(sizeof(StatAddr) / (sizeof(SK_PNMI_STATADDR) * SK_PNMI_MAC_TYPES)))
with the second line being just ARRAY_SIZE(StatAddr), which will always
return SK_PNMI_MAX_IDX, rendering the check useless.
