        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.

depending on the value of the EE_CLK/ADDR4 pin. Support both
configurations by using the sw_addr setting as base address.

1fc050a134 ipv4: Cache source address in nexthop entries.
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().

6247e08618 net: add ndo_fcoe_ddp_target() to support FCoE DDP in target mode
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.
