393775d5c0 ethdev: export function to check port validity
The function rte_eth_dev_is_valid_port is good way to have all
drivers using same function and solves several hotplug related
bugs from drivers not checking attached flag.

7621d6a8d0 eal: add and use unaligned integer types

This patch introduces new unaligned_uint(16|32|64)_t types, which

architectures will need to define CONFIG_RTE_ARCH_STRICT_ALIGN in

64b7acd861 ethdev: add multicast address filtering
With the current PMD API, the receipt of multicast packets on a given
port can only be enabled by invoking the "rte_eth_allmulticast_enable"
function.
This method may not work on Virtual Functions in SR-IOV architectures
when the host PF driver does not allow such operation on VFs.
In such cases, joined multicast addresses must be individually added
in the set of multicast addresses that are filtered by the [VF] port.

For this purpose, a new function "set_mc_addr_list" is introduced
into the set of functions that are exported by a Poll Mode Driver.

467465d86d ethdev: add packet count parameter to Rx callback

This provides the RX callback functions with additional information

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.

14b53e27b3 ethdev: fix crash with multiprocess
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.
