d6b324c00f mbuf: get DMA address
Macros RTE_MBUF_DATA_DMA_ADDR and RTE_MBUF_DATA_DMA_ADDR_DEFAULT
are defined in each PMD driver file. Convert macros to inline
functions and move them to common lib/librte_mbuf/rte_mbuf.h file.
PMD drivers include rte_mbuf.h file directly/indirectly hence no
additioanl header file inclusion is necessary.

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/

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.

7ab8500037 ixgbe: fix VF start with PF stopped
When ixgbe runs as a PF, mbox interrupt is prerequisite to make VF
start normally.
And PF sometimes won't 'dev_start', so the mbox interrupt register
during 'dev_init' is required.
The patch rolls back the interrupt register for mbox,lsc to the 'dev_init'.
As UIO doesn't support multiple vector, mbox has to occupy the only one.
It adds condition check on 'dev_start', rxq interrupt is not allowed
when PF running in IOV mode via UIO.

75e7eb4a01 ixgbe: fix statistics for 82598/82599 differences
Ixgbe based 82598 and 82599 have different priority receive link-on
register addresses. This is solved in base/ by providing in the
PXONRXC and PXONXCNT as separate macros. This patch ensures the
correct address is read, avoiding reading garbage values.

Also PXON2OFFCNT doesn't exist in 82598, so it is not read for
that MAC.

This issue has existed since the drivers were imported into DPDK,
but was not easily discoverable as xstats were not available.

45e73f4208 ixgbe: remove burst size restriction of vector Rx
On receive side, the burst size now floor aligns to RTE_IXGBE_DESCS_PER_LOOP
power of 2. According to this rule, the burst size less than 4 still won't
receive anything.
(Before this change, the burst size less than 32 can't receive anything.)
_recv_*_pkts_vec returns no more than 32(RTE_IXGBE_RXQ_REARM_THRESH) packets.

On transmit side, the max burst size no longer bind with a constant, however
it still requires to check the cross tx_rs_thresh violation.

There's no obvious performance drop found on both recv_pkts_vec
and recv_scattered_pkts_vec on burst size 32.

Niantic HW expects Header Buffer Address in the RXD to be word aligned.
So, if mbuf's buf_physaddr is not word aligned then

Right now, in ixgbe PMD we always setup Packet Buffer Address(PBA) and
Header Buffer Address (HBA) to the same value:
buf_physaddr + RTE_PKTMBUF_HEADROOM.

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.

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

Bug fix to remove (rxnfgpc - hw_stats->gprc) which does not account

hw_stats->gprc is the Number of good (non-erred) Rx packets (from the

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.

forwarding enabled - packets should be dropped and the error counters
incremented.

In order to unify the packet type, the field of 'packet_type' in

Accordingly, some fields in 'struct rte_mbuf' are re-organized to support

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

61e4d90f27 ixgbe: remove a discarded source line
Little endian to CPU order conversion had been added for reading
vlan tag from RX descriptor, while its original source line was
forgotten to delete. That's a discarded source line and should be
deleted.
