gcc permitting variable length arrays makes the current construct used for
BUILD_BUG_ON() useless, as that doesn't produce any diagnostic if the
controlling expression isn't really constant.  Instead, this patch makes
it so that a bit field gets used here.  Consequently, those uses where the
condition isn't really constant now also need fixing.

Note that in the gfp.h, kmemcheck.h, and virtio_config.h cases
MAYBE_BUILD_BUG_ON() really just serves documentation purposes - even if
the expression is compile time constant (__builtin_constant_p() yields
true), the array is still deemed of variable length by gcc, and hence the
whole expression doesn't have the intended effect.

This patch is inspired by patch recently posted by Johannes Berg. Basically what
my patch does is to group list and a count of addresses into newly introduced
structure netdev_hw_addr_list. This brings us two benefits:
1) struct net_device becames a bit nicer.
2) in the future there will be a possibility to operate with lists independently
   on netdevices (with exporting right functions).
I wanted to introduce this patch before I'll post a multicast lists conversion.

This patch converts unicast address list to standard list_head using
previously introduced struct netdev_hw_addr. It also relaxes the
locking. Original spinlock (still used for multicast addresses) is not
needed and is no longer used for a protection of this list. All
reading and writing takes place under rtnl (with no changes).

I also removed a possibility to specify the length of the address
while adding or deleting unicast address. It's always dev->addr_len.

The convertion touched especially e1000 and ixgbe codes when the
change is not so trivial.

Implementing discard counters for the NIU driver turned out to be more
complicated than first assumed.

The discard counters for the NIU neptune chip are only 16-bit (even
though this is a 64-bit chip).  These 16-bit counters can overflow
quickly, especially considering this is a 10Gbit/s ethernet card.

The overflow indication bit is, unfortunatly, not usable as the
counter value does not wrap, but remains at max value 0xFFFF.
Resulting in lost counts until the counter is reset.

The read and reset scheme also poses a problem. Both in theory and in
practice counters can be lost in between reading nr64() and clearing
the counter nw64().  For this reason, the number of counter clearings
nw64() is limited/reduced.  On the fast-path the counters are only
syncronized once it exceeds 0x7FFF.  When read by userspace, its
syncronized fully.

This fixes a TX hang reported by Jesper Dangaard Brouer.

When an architecutre cannot provide a fully functional
64-bit atomic readq/writeq, the driver must implement
it's own.  This is because only the driver can say whether
doing something like using two 32-bit reads to implement
the full 64-bit read will actually work properly.

In particular one of the issues is whether the top 32-bits
or the bottom 32-bits of the 64-bit register should be read
first.  There could be side effects, and in fact that is
exactly the problem here.

The TX_CS register has counters in the upper 32-bits and
state bits in the lower 32-bits.  A read clears the state
bits.

We would read the counter half before the state bit half.
That first read would clear the state bits, and then the
driver thinks that no interrupts are pending because the
interrupt indication state bits are seen clear every time.

Fix this by reading the bottom half before the upper half.
