The previous Phonet patch series introduced per-socket implicit
destination (i.e. connect()). In that case, the destination
socket address is NULL in the transmit function.
However commit a8059512
("Phonet: implement per-socket destination/peer address")
is incomplete and would trigger a NULL dereference.
(Fortunately, the code is not in released kernel, and in fact
 currently not reachable.)

        ixgbe: improve logic in ixgbe_init_mbx_params_pf

incorrectly added a line that accessed mbx->udelay.  I'm sure the intent
was mbx->usec_delay.  This patch fixes the compilation error.

When doing output route lookups, we have to select the source address
if the user has not specified an explicit one.

First, if the route has an explicit preferred source address
specified, then we use that.

Otherwise we search the route's outgoing interface for a suitable
address.

This search can be precomputed and cached at route insertion time.

The only missing part is that we have to refresh this precomputed
value any time addresses are added or removed from the interface, and
this is accomplished by fib_update_nh_saddrs().

The Fiber Channel over Ethernet (FCoE) Direct Data Placement (DDP) can also be
used for FCoE target, where the DDP used for read I/O on an initiator can be
used on an FCoE target to speed up the write I/O to the target from the initiator.
The added ndo_fcoe_ddp_target() works in the similar way as the existing
ndo_fcoe_ddp_setup() to allow the underlying hardware set up the DDP context
accordingly when it gets called from the FCoE target implementation on top
the existing Open-FCoE fcoe/libfc protocol stack so without losing the ability
to provide DDP for read I/O as an initiator, it can also provide DDP offload
to the write I/O coming from the initiator as a target.

fib_semantic_match() requires that if the type doesn't signal an
automatic error, it must be of type RTN_UNICAST, RTN_LOCAL,
RTN_BROADCAST, RTN_ANYCAST, or RTN_MULTICAST.

Checking this every route lookup is pointless work.

Instead validate it during route insertion, via fib_create_info().

Also, there was nothing making sure the type value was less than
RTN_MAX, so add that missing check while we're here.
