18fab3a918 net/cxgbe: implement dynamic log type
The generic RTE_LOGTYPE_PMD is a historical relic and should
be deprecated. Every driver must register its own logtype.

2da3ba7467 net/i40e: fix VF runtime queues RSS config
I40evf queue can not work properly with kernel pf driver for X722 vf.
Eg. when configure 8 queues pair, only 4 queues can receive packets,
and half packets will be lost if using 2 queues pair.

This issue is caused by misconfiguration of look up table, the original
code of LUT configuration did not work for X722 vf, use aq command to
setup the LUT to make it work properly.

68218b87c1 net/bonding: prefer allmulti to promiscuous for LACP
Rather than the global promiscuous mode on all slaves, let's try to use
allmulti.
To do this, we apply the same mechanism than for promiscuous and drop in
rx_burst.

When adding a slave, we first try to use allmulti, else we try
promiscuous.
Because of this, we must be able to handle allmulti on the bonding
interface, so the associated dev_ops is added with checks on which mode
has been applied on each slave.

Rather than add a new flag in the bond private structure, we can remove
promiscuous_en since ethdev already maintains this information.
When starting the bond device, there is no promisc/allmulti re-apply
as, again, ethdev does this itself.

On reception, we must inspect if the packets are multicast or unicast
and take a decision to drop based on which mode has been enabled on the
bonding interface.

Note: in the future, if we define an API so that we can add/remove mc
addresses to a port (rather than the current global set_mc_addr_list
API), we can refine this to only register the LACP multicast mac
address.

0ec234460b net/bonding: fix unicast packets filtering
By default, the 802.3ad code enables promisc mode on all slaves.
To avoid all packets going to the application (unless the application
asked for promiscuous mode), all frames are supposed to be filtered in
the rx burst handler.

However the incriminated commit broke this because non pure ethernet
frames (basically any unicast Ether()/IP() packet) are not filtered
anymore.

8ff0003c19 net/bonding: fix out of bound access in LACP mode
We'd better consolidate the fast queue and the normal tx burst functions
under a common inline wrapper for maintenance.

But looking closer at the bufs_slave_port_idxs[] mapping array in those
tx burst functions, its size is invalid since up to nb_bufs are handled
here.
A previous patch [1] fixed this issue for balance tx burst function
without mentioning it.

802.3ad and balance modes are functionally equivalent on transmit.
The only difference is on the slave id distribution.
Add an additional inline wrapper to consolidate even more and fix this
issue.

47caefc163 eal: increase maximum different hugepage sizes on Arm
ARM is supporting maximum 4 hugepage sizes (64K, 2M, 32M
and 1G) when granule is 4KB since very long and DPDK
support maximum 3 hugepage sizes.

With all 4 hugepage sizes enabled, applications and some
stacks like VPP which are working over DPDK and using
"in-memory" eal option, or using separate mount points
on ARM based platform, fails at huge page initialization,
reporting error messages from eal:

EAL: FATAL: Cannot get hugepage information.
EAL: Cannot get hugepage information.
EAL: Error - exiting with code: 1

This issue is originated from Linux 5.0
(a21b0b78eaf7 "arm64: hugetlb: Register hugepages during arch init")
where kernel is by default creating directories for each supported
hugepage size in /sys/kernel/mm/hugepages/

On earlier Stable Kernel LTR's, the directories visible in
/sys/kernel/mm/hugepages/ were dependent upon what hugepage
sizes are configured at boot time.

This change increases the maximum supported hugepage sizes
to 4 for ARM based platforms.

For the multi segment packets this optimization is not applicable,

we do not have linear array of pointers in pkts parameter.

23bdbfec2b doc: fix wording and formatting of mlx5 guide
These are simple fixes of punctuation, anchor placement
or wording.
The table format is fixed to avoid having a long line
in the first column.

ae28c04547 doc: improve firmware configuration in mlx5 guide
The command mlxconfig was not enough explained and too much verbose
at the same time.
The syntax is now explained in introduction before listing the options,
without repeating the commands.
Some options, which are explained elsewhere in the doc,
are added to this list.

1f1eb0949c net/mlx5: fix UDP checksum zeroing
Function flow_dv_zero_encap_udp_csum() uses a while loop to iterate
over vlan items in flow rule.
Pointer next_hdr is incremented to the next item before it is used,
so the first item is skipped.

This patch moves the incrementing of next_hdr to the correct place.

6fd05da9ef net/mlx5: fix link speed info when link is down
When the link is down, the link speed returned by ethtool is
UINT32_MAX and the link status is 0.

In this case, the DPDK ethdev link speed should be set to
ETH_SPEED_NUM_NONE.
Otherwise since link speed is non-zero but link status is zero, this
is an inconsistent situation and -EAGAIN is returned, which is not right.

f32a3f5216 net/mlx5: fix completion queue overflow for large burst
There is the limit on completion descriptor fetch to improve
latency. If burst size is large there might be not enough
resources freed in completion processing. This fix reiterates
sending loop and allows multiple completion descriptor fetch
and processing.

This patch fixes the default settings for packet size to inline
with Enhanced Multi-Packet Write feature, allowing 256B packets
to be inlined with Out-Of-the-Box settings.

c6f0485646 net/mlx5: fix inline data settings
If the minimal inline data are required the data inline feature
must be engaged. There were the incorrect settings enabling the
entire small packet inline (in size up to 82B) which may result
in sending rate declining if there is no enough cores. The same
problem was raised if inline was enabled to support VLAN tag
insertion by software.

da1df1ccab net/mlx5: fix completion queue drain loop

operations are done - no CQE field fetch on each loop
iteration. Also, code size is oprimized - the flush
buffers routine is invoked once.
