7c574623ba ixgbe: remove Rx bulk allocation option
RTE_LIBRTE_IXGBE_RX_ALLOW_BULK_ALLOC config option is not really
necessary, as bulk alloc rx function can be used anyway, as long as the
necessary conditions are satisfied, which are checked already
in the library.

0369957f27 ixgbe: remove awkward typecasts
The vector/SSE pmd used a different element type for the tx queue sw_ring
entries. This led to lots of typecasts in the code which required specific
use of bracketing, leading to subtle errors.
For example, in the original code:
	txe = (struct ixgbe_tx_entry_v *)&txq->sw_ring[i];
instead needs to be written as:
	txe = &((struct ixgbe_tx_entry_v *)txq->sw_ring)[i];

We can eliminate this problem, by having two software ring pointers in the
structure for the two different element types.

f03b4ea048 ixgbe: rename Tx queue release function
The function inside the vector/SSE poll-mode driver for releasing
the mbufs on the TX queues had the same name as another function
inside the regular PMD. To keep consistency and avoid confusion,
rename the vector PMD version to have a "_vec" suffix.

11b220c649 ixgbe: fix release queue mbufs
The calculations of what mbufs were valid in the RX and TX queues were
incorrect when freeing the mbufs for the vector PMD. This led to crashes
due to invalid reference counts when mbuf debugging was turned on, and
possibly other more subtle problems (such as mbufs being freed when in use)
in other cases.

To fix this, the following changes were made:
* correct counts and post-loop values in the TX release function for the
  vector code.
* create a new separate RX release function for the RX vector code, since the
  tracking of what mbufs are valid or not is different for that code path

3c47efd90d ixgbe: fix Rx error stats
Bug fix to remove (rxnfgpc - hw_stats->gprc) which does not account
for phy errors.
hw_stats->gprc is the Number of good (non-erred) Rx packets (from the
network) that pass L2 filtering and has a legal length as defined by
LongPacketEnable. While rxnfgpc is the Number of good (non-erred with
legal length) Rx packets (from the network) regardless of packet
filtering and receive enablement. Thus hw_stats->gprc can be > rxnfgpc
and this calculation should be removed from the calculation of ierrors.
Validated with testpmd by sending packets to the interface without
forwarding enabled - packets should be dropped and the error counters
incremented.

3962541758 mbuf: redefine packet type
In order to unify the packet type, the field of 'packet_type' in
'struct rte_mbuf' needs to be extended from 16 to 32 bits.

Accordingly, some fields in 'struct rte_mbuf' are re-organized to support
this change for Vector PMD.
As 'struct rte_kni_mbuf' for KNI should be right mapped to
'struct rte_mbuf', it should be modified accordingly.
In ixgbe PMD driver, corresponding changes are added for the mbuf changes,
especially the bit masks of packet type for 'ol_flags' are replaced by
unified packet type. In addition, more packet types (UDP, TCP and SCTP)
are supported in vectorized ixgbe PMD.

To avoid breaking ABI compatibility, all the changes would be enabled by
RTE_NEXT_ABI.

Note that around 2% performance drop (64B) was observed of doing 4 ports

b35d0d80f0 ixgbe: check mbuf refcnt when clearing a ring
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():

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.

55c64cee04 ixgbe/base: enable X550 FEC when EEE is disabled
The FEC(Forward Error Correction) feature had been disabled
because it increases power consumption. However, some customers
want to use it. This patch enables FEC when EEE(Energy Efficient
Ethernet) is disabled; FEC was already being disabled when EEE
was enabled, but now both are done in the same function. The two
features are not allowed to be enabled at the same time. The two
features cannot both be disabled. If this ability is ever
determined to be needed, we will need to define a new user parameter
to control FEC independently of EEE.

Fixes: d4c9ffd4fe1c ("ixgbe/base: disable X550em FEC to save power")

7554abe348 ixgbe/base: check for functional CS4227 ucode
During init, check the ucode running in the CS4227. If
it is not responding correctly, reset the part. This is
a global reset so it must only be done the first time a
driver loads after power-on.

8bdbca1345 ixgbe/base: use a semaphore to serialize X550 IOSF accesses
Because each IOSF access requires the use of multiple registers,
use a semaphore to serialize those accesses.

bde42a2209 ixgbe/base: add wait helper for X550 IOSF accesses
Add a helper function to wait for IOSF accesses to complete. Also
perform this wait before each access, as specified in the datasheet.

2bbe36aaa0 ixgbe/base: add macros for X550em bus speed fuse
x550em has two different bus speeds, 300 MHz and 400 MHz.
A bit in a fuse register tells which it is, with a 1 meaning
the bus is running at 300 MHz.

75a43979c7 ixgbe/base: fix X550em UniPHY link configuration
In UniPHY we have 2 IOSF targets that are UniPHY related. We can
write to PHY and PCS. In earlier times I've been told that there
were 2 separate PCS targets for IOSF commands and that's why I
implemented it with 2 defines and adding hw->bus.lan_id, but lately
I confirmed with HW that FW takes care of which PCS "slice" we are
talking to and is directing writes to correct one, so KX4_PCS1
target is dead now and we cannot use it.

caab86b897 ixgbe/base: power down the X550em PHY on overtemp event
This patch powers down the x550em PHY on over-temp events. The
PHY firmware is supposed to do this autonomously but that isn't
implemented. The short-term stop-gap solution is for SW to power
down the PHY when it reports an overtemp event.
