bb7c5ab2e8 eal: do not reset getopt lib
Someone may need to call rte_eal_init() with a fake argc/argv array
in the middle of using getopt() to parse its own unrelated argc/argv
parameters. So getopt lib shouldn't be reset by rte_eal_init().

Now eal will always save optind, optarg and optopt (and optreset on
FreeBSD) at the beginning, initialize optind (and optreset on FreeBSD)
to 1 before calling getopt_long(), then restore all values after.

d5790b03b3 ethdev: fix link status race condition
Calling the Ethernet driver's link_update function from
rte_eth_dev_start can result in a race condition if the NIC raises
the link interrupt at the same time.
Depending on the interrupt handler implementation, the race can cause
the it to think that it received two consecutive link up interrupts,
and it exits without calling the user callback. Appears to impact
E1000/IGB and virtio drivers only.

256ff05a9c ixgbe: fix Rx errors statistics for UDP checksum
This patch removes l3_l4_xsum_errors from rx errors.

The reason to remove it is that UDP packets have an optional checksum, and
when not calculated the checksum field should be set to zero. When the
checksum is not calculated (zero-ed out), the hardware still counts a valid
UDP packet as an l3_l4_xsum_error.

This hardware issue is documented in 82599 errata, titled:
"Integrity Error Reported for IPv4/UDP Packets with Zero Checksum"

The solution is to remove l3_l4_xsum_errors from rx_errors, as discussed on
http://thread.gmane.org/gmane.comp.networking.dpdk.devel/25590/

6b6861c171 ethdev: check queue state before starting or stopping
Following the same approach taken with dev_started field
in rte_eth_dev_data structure, this patch adds two new fields
in it, rx_queue_state and tx_queue_state arrays, which track
which queues have been started and which not.

This is important to avoid trying to start/stop twice a queue,
which will result in undefined behaviour
(which may cause RX/TX disruption).

Mind that only the PMDs which have queue_start/stop functions
have been changed to update this field, as the functions will
check the queue state before switching it.

not changing the current default behavior. The application itself can

5b720dc643 lpm: fix condition check in delete
Fixes an issue of check logic in delete_depth_small function.

For a tbl24 entry, the 'ext_entry' field indicates whether we need
to use tbl8_gindex to read the next_hop from a tbl8 entry, or whether
it can be read directly from this entry.

If a route is deleted, the prefix of previous route is used to override
the deleted route.

When checking the depth of the previous route the conditional checks
both the ext_entry and the depth, but the "else" leg fails to take
account that the condition could fail for one of two possible reasons,
leading to an incorrect flow when 'ext_entry == 0' is true,
but 'lpm->tbl24[i].depth > depth' is false.
The fix here is to add a condition check to the else leg so that it
only executes when ext_entry is set.
