qlge: fix size of external list for TX address descriptors
When transmiting a fragmented skb, qlge fills a descriptor with the
fragment addresses, after DMA-mapping them. If there are more than eight
fragments, it will use the eighth descriptor as a pointer to an external
list. After mapping this external list, called OAL to a structure
containing more descriptors, it fills it with the extra fragments.
However, considering that systems with pages larger than 8KiB would have
less than 8 fragments, which was true before commit a715dea3c8e, it
defined a macro for the OAL size as 0 in those cases.
Now, if a skb with more than 8 fragments (counting skb->data as one
fragment), this would start overwriting the list of addresses already
mapped and would make the driver fail to properly unmap the right
addresses on architectures with pages larger than 8KiB.
Besides that, the list of mappings was one size too small, since it must
have a mapping for the maxinum number of skb fragments plus one for
skb->data and another for the OAL. So, even on architectures with page
sizes 4KiB and 8KiB, a skb with the maximum number of fragments would
make the driver overwrite its counter for the number of mappings, which,
again, would make it fail to unmap the mapped DMA addresses.

tg3: switch to build_skb() infrastructure
This is very similar to bnx2x conversion, but simpler since no special
alignement is required, so goal was not to reduce skb truesize.
Using build_skb() reduces cache line misses in the driver, since we
use cache hot skb instead of cold ones. Number of in-flight sk_buff
structures is lower, they are more likely recycled in SLUB caches
while still hot.

We need to mask the MMC irq otherwise if we raise the mmc
interrupts that are not handled the driver loops in the
handler.
In fact, by default all mmc counters (only used for stats)
are managed in SW and registers are cleared on each READ.

net: Change mii to ethtool advertisement function names
This patch implements advice by Ben Hutchings to change the mii side of
the function names to look more like the register whose values they
convert. New LPA translation functions have been added as well.

ksz884x: Use kzalloc rather than kmalloc followed by memset with 0
This considers some simple cases that are common and easy to validate
Note in particular that there are no ...s in the rule, so all of the
matched code has to be contiguous
The semantic patch that makes this change is available
