net/iavf: improve performance of Rx timestamp offload
In this patch, We use CPU ticks instead of HW register
to determine whether low 32 bits timestamp has turned
over. It can avoid requesting register value frequently
and improve receiving performance.

net/iavf: remove extra copy step in Rx bulk path
In the Rx bulk path, packets which are taken from the HW ring, are first
copied to the stage data structure and then later copied from the stage
to the rx_pkts array. For the number of packets requested immediately
by the receiving function, this two-step process adds extra overhead
that is not necessary.
Instead, put requested number of packets directly into the rx_pkts array
and only stage excess packets. On N1SDP with 1 core/port, l3fwd saw up
to 4% performance improvement. On x86, no difference in performance was
observed.

When setup Rx queue, the rxdid would be changed if it's

function 'iavf_rx_scan_hw_ring_flex_rxd()'.
Ignore the rxdid changed when equals "IAVF_RXDID_LEGACY_0/1".

net/iavf: remove extra check in vector Tx
In the vector Tx path, the function iavf_xmit_pkts_vec_xxx compares

net/iavf: remove extra check in vector Tx
In the vector Tx path, the function iavf_xmit_pkts_vec_xxx compares
nb_pkts and the txq->rs_thresh and passes the minimum of these as an
argument to iavf_xmit_fixed_burst_vec_xxx.
Inside iavf_xmit_fixed_burst_vec_xxx, the same check is performed again.
This patch removes the redundant check from the
iavf_xmit_fixed_burst_vec_xxx function.

This patch uses the index value to call the function, instead of the
function pointer assignment to save the selection of Receive Flex
Descriptor profile ID.
Otherwise the secondary process will run with wrong function address
