rte_ipv4_fragment_packet() and rte_ipv6_fragment packet()
call rte_pktmbuf_attach() to attach the segment of the original
packet to the segment of the new fragmented one. Such function
is not declared if RTE_MBUF_REFCNT is disabled, as it needs to
call rte_mbuf_refcnt_update, not declared either.
Therefore, the ipv4/v6 fragmentation libraries are disabled
in that situation.

If the vector pmd option is turned on in the compile time config file,
then always call the vector rxq setup, since we can now use the vector
PMD for receiving jumbo frames that need chained mbufs, a.k.a scattered
packets. Up till now, this function was not being called when receiving
scattered packets, potentially leading to problems with mbufs not being

The previous implementation of rte_kni_alloc() was allocating memzones with a
name composed of a fixed string and the interface name. When an application was
allocating and deallocating multiple interfaces with different names, memzones
were quickly exhausted, even though memzones from deallocated interfaces were
never used anymore (unless an interface with the same name was re-allocated).
As a result, the application was unable to allocate more KNI interfaces with
different names.
This patch implements the KNI memzone pool in order to prevent memzone
exhaustion when allocating/deallocating KNI interfaces. It adds a new API call,
rte_kni_init(max_kni_ifaces) that shall be called before any call to
rte_kni_alloc() if KNI is used. The memzones are pre-allocated with interface-
independent names so that they can be reused.

The four-byte-key (fbk) autotest was allocating the keys to be used for
the test on the stack. When the number of entries in the table was
increased significantly, for example, to test larger hashes by increase the
value of ENTRIES, this array of keys was greater than that
allowed on the stack, and so caused problems, i.e. crashes and core dumps.
The solution is to have the keys dynamically allocated on the heap using
malloc. Now if ENTRIES is increased and we run out of memory we get an
error message instead of a crash.
