Some drivers are using skb_transport_offset(skb) instead of skb->csum_start
for NETIF_F_HW_CSUM offload.  This does not matter now, but if someone
implements checksumming of encapsulated packets then this will break silently.

TSO output paths are left as they are, since they are for IP+TCP only
(might be worth converting though).

This patch provices the debugfs interface to see RLB hash table
like the following:

# cat /sys/kernel/debug/bonding/bond0/rlb_hash_table
SourceIP        DestinationIP   Destination MAC   DEV
10.124.196.205  10.124.196.205  ff:ff:ff:ff:ff:ff eth4
10.124.196.205  10.124.196.81   00:19:99:XX:XX:XX eth3
10.124.196.205  10.124.196.1    00:21:d8:XX:XX:XX eth0

This is helpful to check if the receive load balancing works as expected.

Make all RTAX_ADVMSS metric accesses go through a new helper function,
dst_metric_advmss().

Leave the actual default metric as "zero" in the real metric slot,
and compute the actual default value dynamically via a new dst_ops
AF specific callback.

For stacked IPSEC routes, we use the advmss of the path which
preserves existing behavior.

Unlike ipv4/ipv6, DecNET ties the advmss to the mtu and thus updates
advmss on pmtu updates.  This inconsistency in advmss handling
results in more raw metric accesses than I wish we ended up with.
