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

Crack open GRE packets in __skb_get_rxhash to compute 4-tuple hash on
in encapsulated packet. Note that this is used only when the
__skb_get_rxhash is taken, in particular only when the device does
not compute provide the rxhash (ie. feature is disabled).
This was tested by creating a single GRE tunnel between two 16 core
AMD machines. 200 netperf TCP_RR streams were ran with 1 byte
request and response size.
Without patch: 157497 tps, 50/90/99% latencies 1250/1292/1364 usecs

The l4_rxhash flag was added to the skb structure to indicate
that the rxhash value was computed over the 4 tuple for the
packet which includes the port information in the encapsulated
transport packet. This is used by the stack to preserve the
rxhash value in __skb_rx_tunnel.

Remove the now-redundant text from field descriptions.

Signed-off-by: David S. Miller <davem@davemloft.net>
The current descriptions state that these fields specify 'How many
packets to delay ... after a packet ...' which implies that the
hardware should wait for (max_coalesced_frames + 1) completions before
generating an interrupt. It is also stated that setting both this
field and the corresponding 'coalesce_usecs' field to 0 is invalid.
Together, this implies that the hardware must always be configured
to delay a completion IRQ for at least 1 usec or 1 more completion.
I believe that the addition of 1 is not intended, and David Miller
confirms that the original implementation (in tg3) does not do this.
Clarify the descriptions of these fields to avoid this interpretation.

This patch extends the HiperSockets device driver to send and receive
af_iucv traffic over HiperSockets transport.
TX: Driver uses new asynchronous delivery of storage blocks to pass
flow control/congestion information from the HiperSockets microcode
to the af_iucv socket.
RX: Memory for incoming traffic is preallocated and passed to
HiperSockets layer. If receiver is not capable to clean its buffers
shared with HiperSockets and pass new memory to the HiperSockets
layer this will cause flow control/congestion events on the
sender.
