iproute2 doesn't provide the NLM_F_CREATE flag when adding addresses,
it is assumed to be implied. The existing code issues a check on
said flag when the modify operation fails (likely due to ENOENT)
before continueing to create it, this leads to a hard to predict
result, therefore the NLM_F_CREATE check is removed.

By passing a Linux-generated TSO packet straight back into Linux, Xen
becomes our first LRO user :) Unfortunately, there is at least one spot
in our stack that needs to be changed to cope with this.

The receive MSS estimate is computed from the raw packet size.  This is
broken if the packet is GSO/LRO.  Fortunately the real MSS can be found
in gso_size so we simply need to use that if it is non-zero.

Real LRO NICs should of course set the gso_size field in future.

Introduces a new attribute type NLA_NUL_STRING to support NUL

a terminating NUL within the maximum specified in the policy.

The `old' NLA_STRING which is not required to be NUL terminated
is extended to provide means to specify a maximum length of the
string.

Aims at easing the pain with using nla_strlcpy() on temporary
