e4f4722c14 ixgbe/base: abstract out link read/write
It's more valuable to abstract the link read/write interface. As such,
change the following method names, and add them to a new link info
structure:
  read_i2c_combined               => read_link
  read_i2c_combined_unlocked      => read_link_unlocked
  write_i2c_combined              => write_link
  write_i2c_combined_unlocked     => write_link_unlocked

This will allow X550EM_a to override these methods for MDIO access
while X550EM_x provides methods to use I2C combined access.
Initially the structure is just method pointers and a bus
address.

Two functions involved in combined I2C accesses were moved from
ixgbe_phy.c to ixgbe_x550.c. The underlying functions that carry
out the combined I2C accesses were left in ixgbe_phy.c because
they share some functions with other I2C methods.

0cf7c6a6f3 ixgbe/base: set MDIO speed after MAC reset
The MDIO clock speed must be reconfigured after the MAC reset.
The MDIO clock speed becomes invalid, therefore the driver reads
invalid PHY register values. The driver now set the MDIO clock
speed prior to initializing PHY ops and again after the MAC reset.

As now the MDIO speed gets set in more than one place, make a
function for it so it will always be done correctly.

e2f368a4bf ixgbe/base: fix setting flow director flag twice
Do not set FDIRCTRL.DROP_NO_MATCH in ixgbe_init_fdir_perfect_82599(),
this bit is already set in ixgbe_set_fdir_drop_queue_82599() which
makes more sense for drivers that call that function.

This resolves an issue where packets were being dropped when switching
to perfect filters mode.

Setting this bit makes no sense in perfect filters mode for the
driver as we do not want to route all packets that don't match an FDIR
rule to a single queue and instead fall back to RSS.
Drivers that need this bit set can call ixgbe_set_fdir_drop_queue_82599()
and the ones that don't, can preserve the old behavior.

0c14952f17 ixgbe/base: add register definition for SGMII busy
The X550EM_a device provides the MAC_SGMII_BUSY register to
indicate when slow SGMII register writes complete. Add
definitions for the register. No definitions are provided for
the individual bits under the theory that it is better to wait
for everything to complete when needed rather than try to map
out which reads need to wait for which writes. So we should wait
when anything is marked as "busy".

43a942393d ixgbe: select pool by MAC when using double VLAN
On X550, as required by datasheet, E-tag packets are not expected
when double VLAN are used. So modify the register PFVTCTL after
enabling double VLAN to select pool by MAC but not MAC or E-tag.

An introduction of E-tag:
It's defined in IEEE802.1br. Please reference this website,
http://www.ieee802.org/1/pages/802.1br.html.

A brief description.
E-tag means external tag, and it's a kind of l2 tunnel. It means a
tag will be inserted in the l2 header. Like below,
   |31            24|23           16|15         8|7           0|
  0|                   Destination MAC address                 |
  4|     Dest MAC address(cont.)    |     Src MAC address      |
  8|                  Source MAC address(cont.)                |
 12| E-tag Etherenet type (0x893f)  |      E-tag header        |
 16|                    E-tag header(cont.)                    |
 20|   VLAN Ethertype(optional)     |   VLAN header(optional)  |
 24|         Original type          |         ......           |
...|                              ......                       |
The E-tag format is like below,
   |0                    15|16   18|19 |20                   31|
   |   Ethertype - 0x893f  | E-PCP |DEI|   Ingress E-CID_base  |

   |32  33|34 35|36      47|48         55    |56             63|
   |  RSV | GRP |E-CID_base|Ingress_E-CID_ext|    E-CID_ext    |

The Ingess_E-CID_ext and E-CID_ext are always zero for endpoints
and are effectively reserved.

The more details of E-tag is in IEEE 802.1BR. 802.1BR is used to
replace 802.1Qbh. 802.1BR is a standard for Bridge Port Extension.
It specifies the operation of Bridge Port Extenders, including
management, protocols, and algorithms. Bridge Port Extenders
operate in support of the MAC Service by Extended Bridges.
The E-tag is added to l2 header to identify the VM channel and
the virtual port.

71f39b07b6 ixgbe: fix Tx hang when RS distance exceeds HW limit
One of the ways to reproduce the issue:

testpmd <EAL-OPTIONS> -- -i --txqflags=0
testpmd> set fwd txonly
testpmd> set txpkts 64,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4
testpmd> set txsplit rand
testpmd> start

After some time TX on ixgbe queue will hang,
and all packet transmission on that queue will stop.

This bug was first reported and investigated by
Vlad Zolotarov <vladz@cloudius-systems.com>:
"We can reproduce this issue when stressed the xmit path with a lot of highly
fragmented TCP frames (packets with up to 33 fragments with non-headers
fragments as small as 4 bytes) with all offload features enabled."

The root cause is that ixgbe_xmit_pkts() in some cases violates the HW rule
that the distance between TDs with RS bit set should not exceed 40 TDs.

>From the latest 82599 spec update:
"When WTHRESH is set to zero, the software device driver should set the RS bit
in the Tx descriptors with the EOP bit set and at least once in the 40
descriptors."

The fix is to make sure that the distance between TDs with RS bit set
would never exceed HW limit.
As part of that fix, tx_rs_thresh for ixgbe PMD is not allowed to be greater
then to 32 to comply with HW restrictions.

With that fix slight slowdown for the full-featured ixgbe TX path
might be observed (from our testing - up to 4%).

ixgbe simple TX path is unaffected by that patch.

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/

Fixes: f6bf669b9900 ("ixgbe: account more Rx errors")

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.
