This reverts commit efa230f2c6.
BQL doesn't work with how this driver currently only takes TX
interrupts every 1/4 of the TX ring. That behavior needs to be fixed,
but that's a larger non-trivial task and for now we have to revert
BQL support as this makes the device currently completely unusable.

The idea here seems to be to get a 44bit DMA mask working and if this
fails it should fallback to a 32bit DMA mask. The dma_mask variable is
assigned once to 44bit and never updated. pci_set_dma_mask() and
pci_set_consistent_dma_mask() are both implemented as functions so there
is no evil macro which might update dma_mask. Looking at the assembly, I
see a call to dma_set_mask() followed by dma_supported() and then a jump
passed the second dma_set_mask(). The only way to get to second
dma_set_mask() call is by an error code in the first one.
So I hereby remove the check since it looks superfluous. Please ignore
the path if there is black magic involved.

Unify return value of .ndo_set_mac_address if the given address
isn't valid. Return -EADDRNOTAVAIL as eth_mac_addr() already does
if is_valid_ether_addr() fails.

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.

Translating between ethtool advertisement settings and MII
advertisements are common operations for ethernet drivers. This patch
adds a set of helper functions that implements the conversion. The
patch then modifies a couple of the drivers to use the new functions.

Perform another round of floor sweeping, converting the .get_drvinfo
routines of additional drivers from strcpy to strlcpy along with
some conversion of sprintf to snprintf.

To ease skb->truesize sanitization, its better to be able to localize
all references to skb frags size.
Define accessors : skb_frag_size() to fetch frag size, and
skb_frag_size_{set|add|sub}() to manipulate it.

A user-space process must use ETHTOOL_GRXCLSRLCNT to find the number
of classification rules, then allocate a buffer of the right size,
then use ETHTOOL_GRXCLSRLALL to fill the buffer. If some other
process inserts or deletes a rule between those two operations,
the user buffer might turn out to be the wrong size.
If it's too small, the return value will be -EMSGSIZE. But if it's
too large, there is no indication of this. Fix this by updating
the rule_cnt field on return.

Correct the description of ethtool_rxnfc::rule_locs; it is an array
of currently used locations, not all possible valid locations.
Add note that drivers must not use ethtool_rxnfc::rule_locs.
The rule_locs argument to ethtool_ops::get_rxnfc is either NULL or a
pointer to an array of u32, so change the parameter type accordingly.

Use IFF_UNICAST_FTL to find out if driver handles unicast address
filtering. In case it does not, promisc mode is entered.
Patch also fixes following drivers:
stmmac, niu: support uc filtering and yet it propagated
ndo_set_multicast_list
bna, benet, pxa168_eth, ks8851, ks8851_mll, ksz884x : has set

Moves the Sun drivers into drivers/net/ethernet/sun/ and make
the necessary Kconfig and Makefile changes.
Oliver Hartkopp <socketcan@hartkopp.net> suggested removing the
sun* prefix on the driver names. This type of change I will
leave up to the driver maintainers.
