timer: fix race condition
Eliminate problematic race condition in rte_timer_manage() that can
lead to corruption of per-lcore pending-lists (implemented as
skip-lists). The race condition occurs when rte_timer_manage() expires
multiple timers on lcore A, while lcore B simultaneously invokes
rte_timer_reset() for one of the expiring timers (other than the first
one).
Lcore A splits its pending-list, creating a local list of expired timers
linked through their sl_next[0] pointers, and sets the first expired
timer to the RUNNING state, all during one list-lock round trip.
Lcore A then unlocks the list-lock to run the first callback, and that
is when A and B can have different interpretations of the subsequent
expired timers' true state. Lcore B sees an expired timer still in the
PENDING state, atomically changes the timer to the CONFIG state, locks
lcore A's list-lock, and reinserts the timer into A's pending-list.
The two lcores try to use the same next-pointers to maintain both lists!
Our solution is to remove expired timers from the pending-list and try
to set them all to the RUNNING state in one atomic step, i.e.,
rte_timer_manage() should perform these two actions within one
ownership of the list-lock.
After splitting the pending-list at the current point in time and trying
to set all expired timers to the RUNNING state, we must put back into
the pending-list any timers that we failed to set to the RUNNING state,
all while still holding the list-lock. It is then safe to release the
lock and run the callback functions for all expired timers that remain
on our local run-list.

timer: add race condition test
Add new timer-manage race-condition test: We wrote a test to confirm
our suspicion that we could crash rte_timer_manage() under the right
circumstances. We repeatedly set several timers to expire at roughly
the same time on the master core. The master lcore just delays and runs
rte_timer_manage() about ten times per second. The slave lcores all
watch the first timer (timer-0) to see when rte_timer_manage() is
running on the master, i.e., timer-0's state is not PENDING.
At this point, each slave attempts to reset a subset of the timers to
a later expiration time. The goal here is to have the slaves moving
most of the timers to a different place in the master's pending-list,
while the master is traversing the same next-pointers (the slaves'
sl_next[0] pointers) and running callback functions. This eventually
results in the master traversing a corrupted linked-list.
In our observations, it results in an infinite loop.

To resolve, we construct simple synchronization primitives that use one

mbuf: enforce alignment of private area
It looks better to have a data buffer address that is aligned to
8 bytes. This is the case when there is no mbuf private area, but
if there is one, the alignment depends on the size of this area
that is located between the mbuf structure and the data buffer.
Indeed, some drivers expects to have the buffer address aligned
to an even address, and moreover an unaligned buffer may impact
the performance when accessing to network headers.
Add a check in rte_pktmbuf_pool_create() to verify the alignment
constraint before creating the mempool. For applications that use
the alternative way (direct call to rte_mempool_create), also
add an assertion in rte_pktmbuf_init().

examples/l3fwd-power: enable one-shot Rx interrupt and polling switch
The patch demonstrates how to handle per rx queue interrupt in a NAPI-like
implementation in userspace. The working thread mainly runs in polling mode
and switch to interrupt mode only if there is no packet received in recent polls.
The working thread returns to polling mode immediately once it receives an
interrupt notification caused by the incoming packets.
The sample keeps running in polling mode if the binding PMD hasn't supported
the rx interrupt yet. Now only ixgbe(pf/vf) and igb support it.

cxgbe: enable build on FreeBSD
Fix "MACRO redefined" and "function redefined" compilation errors in FreeBSD
by adding CXGBE prefix to them. Also remove reference to a linux header
linux/if_ether.h and use DPDK macros directly. Finally, enable CXGBE PMD
for FreeBSD.

nic_uio: allow to bind any device
nic_uio requires the pci ids to be present in rte_pci_dev_ids.h in order to
bind the devices to nic_uio. However, it's better to remove this whitelist
of pci ids, and instead rely on hw.nic_uio.bdfs kenv parameter to allow
binding any device to nic_uio.
