Added a parameter to the RX callback to pass in the number of
available RX packets in addition to the number of dequeued packets.
This provides the RX callback functions with additional information
that can be used to decide how packets from a burst are handled.
The TX callback doesn't require this additional parameter so the RX
and TX callbacks no longer have the same function parameters. As such
the single RX/TX callback has been refactored into two separate callbacks.

Field ig_vlan_strip_en in struct enic type is int. It is used only by
function enic_set_nic_cfg which expects uint_8 as argument. Changed type

The data structure for the rx and tx callbacks is local to each process
since it contains function pointers and cannot be shared between
different unique binaries. However, because it is not in
rte_eth_dev_data structure, the array is not getting initialized for
secondary processes - neither is it getting appropriately resized if the
number of RX/TX queues changes. This causes crashes in secondary
processes as they dereference a null pointer in struct rte_eth_dev.
This patch fixes this by introducing an upper-bound on the number of
queues per port that can be configured, and then uses this to make the
array statically sized, thereby avoiding the crashes.
