It configures specific registers to enable double vlan stripping
on RX side and insertion on TX side.
The RX descriptors will be parsed, the vlan tags and flags will be
saved to corresponding mbuf fields if vlan tag is detected.
The TX descriptors will be configured according to the
configurations in mbufs, to trigger the hardware insertion of
double vlan tags for each packets sent out.

The parameter tx_free_thresh is not consistent between the drivers:
some use it as rte_eth_tx_burst() requires, some release buffers when
the number of free descriptors drop below this value.
Let's use it as most fast-path code does, which is the latter, and update
comments throughout the code to reflect that.

The function to clear the TX ring when a port was being closed, e.g. on
exit in testpmd, was not checking the mbuf refcnt before freeing it.
Since the function in the vector driver to clear the ring after TX does
not set the pointer to NULL post-free, this caused crashes if mbuf
debugging was turned on.
To reproduce the issue, ensure the follow config variables are set:
RTE_IXGBE_INC_VECTOR
RTE_LIBRTE_MBUF_DEBUG
Then compile up and run testpmd using 10G ports with the vector driver.
Start traffic and let some flow through, then type "stop" and "quit" at
the testpmd prompt, and crash will occur. Output below:
testpmd> quit
Stopping port 0...done
Stopping port 1...PANIC in rte_mbuf_sanity_check():

As well as the fast-path functions in the rxtx code, there are also
functions which set up and tear down the descriptor rings. Since these
are not performance critical functions, there is no need to have them
extensively optimized, so we add __attribute__((cold)) to their
definitions. This has the side-effect of making debugging them easier as
the compiler does not optimize them as heavily, so more variables are
accessible by default in gdb.

When compiling the cxgbe driver with icc, multiple errors about using
enums as integers appear across a number of files, including in the base
code and in the DPDK-specific driver code.

For the errors in the base driver code we use the CFLAGS_BASE_DRIVER
approach used by other drivers to disable warnings.
For errors in the DPDK-specific code, typecasts are used to fix the
errors in the code itself.

TX queue elements (struct txq_elt) contain WR and SGE structures required by
ibv_post_send(). This commit replaces them with a single pointer to the
related TX mbuf considering that:
- There is no need to keep these structures around forever since the
hardware doesn't access them after ibv_post_send() and send_pending*()
have returned.
- The TX queue index stored in the WR ID field is not used for completions
anymore since they use a separate counter (elts_comp_cd).
- The WR structure itself was only useful for ibv_post_send(), it is
currently only used to store the mbuf data address and an offset to the
mbuf structure in the WR ID field. send_pending*() callbacks only require
SGEs or buffer pointers.
Therefore for single segment mbufs, send_pending() or send_pending_inline()
can be used directly without involving SGEs. For scattered mbufs, SGEs are
allocated on the stack and passed to send_pending_sg_list().

This patch adds max_link_up_time parameter to mac structure.
This parameter is used to control maximum link polling time in
ixgbe_check_mac_link functions. It is required to prevent long wait
time on x550 PHY that have no external link.
Since x550 is handled by software, we have to reset internal (PHY to
PHY) link when external link changes, and after reset, we have to wait for
this link to be established. As a result of not having interrupts, we have
to poll for link state, and we know that this link comes up much faster
than default 9 seconds. This parameter is added to prevent waiting 9
seconds for link when external link is not established.
