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
ndo_set_rx_mode but do not support uc filtering

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.
