This change is meant to add an ntuple data extensions to the rx network flow
classification specifiers.  The idea is to allow ntuple to be displayed via
the network flow classification interface.

The first patch had some left over stuff from the original flow extension
flags I had added.  That bit is removed in this patch.

The second had some left over comments that stated we ignored bits in the
masks when we actually match them.

This work is based on input from Ben Hutchings.

This change is meant to prevent a possible null pointer dereference if
NETIF_F_NTUPLE is defined but the set_rx_ntuple function pointer is not.

The main motivation behind this patch is to eventually replace the ntuple
interfaces entirely with the network flow classifier interfaces.  This
allows the device drivers to maintain the ntuple check internally while
using the network flow classifier interface for setting up and displaying
rules.

This also fixes possible race when changing receive checksum state
and removes IPV6_CSUM_GEN_HACK as it's always set.

BTW, The claim about fake IPV6 checksum looks dubious. If that were true,
then there's a problem in networking core and should be fixed there and not
in random drivers.

BTW#2, there's no MAINTAINERS entry for this driver. I assume this driver
is supported by Micrel?

This also removes TSO as it's made fully in software --- better to leave this
to networking core.

If the MAC features can be detected at probe time and not at open, then
stmmac_fix_features could be simplified by limiting hw_features. That's
also better for users as they don't see offloads being togglable but
never turned on.

Redundant fallbacks for TX csum are removed as it's already handled
by network core.

The reverse path filter interferes with IPsec subnet-to-subnet tunnels,
especially when the link to the IPsec peer is on an interface other than
the one hosting the default route.

With dynamic routing, where the peer might be reachable through eth0
today and eth1 tomorrow, it's difficult to keep rp_filter enabled unless
fake routes to the remote subnets are configured on the interface
currently used to reach the peer.

IPsec provides a much stronger anti-spoofing policy than rp_filter, so
this patch disables the rp_filter for packets with a security path.

When cnic_stop_hw() -> cnic_cm_stop_bnx2x_hw() is called under rtnl_lock()
from NETDEV_DOWN event, it waits for cnic_delete_task() to complete.
It will deadlock when cnic_delete_task() takes rtnl_lock() before
calling cnic_ulp_stop_one().

We fix it by removing the rtnl_lock() in cnic_delete_task().
cnic_ulp_stop_one() has mutex and atomic bit ops to prevent important
operations from being done more than once, so it is not necessary to take
rtnl_lock().

Commit 1018b5c0 ("Set rt->rt_iif more
sanely on output routes.")  breaks rt_is_{output,input}_route.

This became the cause to return "IP_PKTINFO's ->ipi_ifindex == 0".

To fix it, this does:

1) Add "int rt_route_iif;" to struct rtable

2) For input routes, always set rt_route_iif to same value as rt_iif

3) For output routes, always set rt_route_iif to zero.  Set rt_iif
   as it is done currently.

4) Change rt_is_{output,input}_route() to test rt_route_iif
