Commit 45f119bf936b ("tcp: remove header prediction") introduced a
minor bug: the sk_state_change() and sk_wake_async() notifications for
a completed active connection happen twice: once in this new spot
inside tcp_finish_connect() and once in the existing code in
tcp_rcv_synsent_state_process() immediately after it calls
tcp_finish_connect(). This commit remoes the duplicate POLL_OUT
notifications.

It's been a while now since ds->dst is not an array anymore, but a
simple pointer to a dsa_switch_tree.
Fortunately, SF2 does not support multi-chip and thus ds->index is
always 0.
This patch substitutes 'ds->dst[ds->index].' with 'ds->dst->'.

in this case. Reduce the memory footprint of the rds module

Now that we provide offload indication using the nexthop's flags we must
refresh the offload indication whenever the offload state within the
group changes.
This didn't matter until now, as offload indication was provided using
the FIB info flags and multipath routes were marked as offloaded as long
as one of the nexthops was offloaded.

Previous patch removed the reliance on the counter in the FIB info to
set the offload indication, so we no longer need to keep an offload
state on each FIB entry and can just set or unset the RTNH_F_OFFLOAD
flag in each nexthop.
This is also necessary because we're going to need to refresh the
offload indication whenever the nexthop group associated with the FIB
entry is refreshed. Current check would prevent us from marking a newly
resolved nexthop as offloaded if the FIB entry is already marked as
offloaded.

In a similar fashion to previous patch, use the nexthop flags to provide
offload indication instead of the FIB info's flags.
In case a nexthop in a multipath route can't be offloaded (gateway's MAC
can't be resolved, for example), then its offload flag isn't set.

This patch implements transparent fail over from synthetic NIC to
SR-IOV virtual function NIC in Hyper-V environment. It is a better
alternative to using bonding as is done now. Instead, the receive and
transmit fail over is done internally inside the driver.
Using bonding driver has lots of issues because it depends on the
script being run early enough in the boot process and with sufficient
information to make the association. This patch moves all that
functionality into the kernel.

The last patch added the dependency on 'OF && HAS_IOMEM' but left
COMPILE_TEST as an alternative, which kind of defeats the purpose
of adding the dependency, we still get randconfig build warnings:
warning: (NET_DSA_BCM_SF2 && BCMGENET) selects MDIO_BCM_UNIMAC which has unmet direct dependencies (NETDEVICES && MDIO_BUS && HAS_IOMEM && OF_MDIO)
For compile-testing purposes, we don't really need this anyway,
as CONFIG_OF can be enabled on all architectures, and HAS_IOMEM
is present on all architectures we do meaningful compile-testing on
(the exception being arch/um).
This makes both OF and HAS_IOMEM hard dependencies.
