As driver flag of 'RTE_PCI_DRV_INTR_LSC' was introduced
recently, it must be added in i40e. One second waiting
is needed for link up event, to wait the hardware into a
stable state, so the interrupt could be processed in two

kni: memzone pool for alloc and release
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-

app/test: fix crash for fbk hashes with a lot of entries
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.
