ICC requires an initializer be given for the static variables,
so adding one in cases where one wasn't previously given.
This problem was introduced in commit e8ae856140
(fix index overflow when resetting big queues).

Rings are resetted with a loop because memset cannot be used without
issuing a warning about volatile casting.
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 rings are configured for 4096 entries
(descriptor size is 16 bytes). The result is an endless loop.
It is fixed by indexing ring entries and resetting all bytes of the entry
with a simple assignment.
The descriptor initializer is zeroed thanks to its static declaration.
There already was a fix for ixgbe Tx only
(commit bcf457f8c0).
It is reverted to use the same fix everywhere (Rx/Tx for igb/ixgbe).

The base driver supports more NICs:
- i210 flashless
- i217
- i218
- i354
The new features are not automatically used by the DPDK PMD.

In case of multi-process application, the secondary process can initialize
the driver without configuring queues. In this case the Rx/Tx functions
were not initialized because it was only done in queue setup.
Fix by reproducing the same behaviour as in eth_igb_dev_init().

When in 'normal' mode, hardware is designed to receive up to 1522 bytes.
When in 'jumbo' mode, RLPML register must be updated so that hardware accepts
a 802.1q vlan header. If dual vlan is enabled, then a second vlan header is
expected, so update RLPML register according to dual vlan support.

The 82576 has known issues which require the write threshold to be set to 1.

If not then single packets will hang in transmit ring until more arrive.
Simple tests like ping will fail.

Need to change PCI code to support multiple I/O regions on a single device.
Some devices like VMXNET3 have multiple PCI memory regions, and some
have none.
