When fast path operation is introduced, the Rx/Tx function is done by
object 'rte_eth_fp_ops'. So 'rte_eth_fp_ops' should be updated if
'fast-path functions' need to be changed, such as PMD receive function,
prepare function and so on.
This patch fixed receiving packets bug when fast path operation is
introduced.

If hardware supports IEEE 1588 PTP, PTP capability will be set. Currently,
vec and sve burst is unsupported when PTP capability is set.
For sake of Rx/Tx performance, IEEE 1588 PTP is not supported in sve or
vec burst mode. When enabling IEEE 1588 PTP, Rx/Tx burst mode should be
simple or common. Rx/Tx burst mode could be set like this, for example:
-a 0000:35:00.0,rx_func_hint=common,tx_func_hint=common
This patch supports vec and sve burst when PTP is disabled. And only
support simple or common burst When PTP is enabled.
