kni: fix X540 init

KNI must not do hardware reset. But it was resetting X540 devices.

This bug was in the first KNI version
(commit 3fc5ca2f63529ec5ad7b1b75f517d61dc7613bd9).

ixgbe: fix index overflow when resetting big Tx queues

The index of the loop was a 16-bit variable which is sufficient for
ring entries number but not for the byte size of the whole ring.
The overflow happens when queue rings are configured for 4096 entries
(descriptor size is 16 bytes). The result is an endless loop.

For compatible processors, they are equivalent.

http://www.intel.com/Assets/PDF/manual/325383.pdf:
"
When executing a spin-wait loop, a Pentium 4 or Intel Xeon processor suffers
a severe performance penalty when exiting the loop because it detects a
possible memory order violation.
The PAUSE instruction provides a hint to the processor that the code sequence
is a spin-wait loop. The processor uses this hint to avoid the memory order
violation in most situations, which greatly improves processor performance.
