7d0c832709 net/tap: check interface name in kvargs
If interface name is passed to remote or iface then check
the length and for invalid characters. This avoids problems where
name gets truncated or rejected by kernel.

2c0dd7b69f config: add static linkage of mlx dependency
The libraries provided by rdma-core may be statically linked
if enabling CONFIG_RTE_IBVERBS_LINK_STATIC in the make-based build.
If CONFIG_RTE_BUILD_SHARED_LIB is disabled, the applications
will embed the mlx PMDs with ibverbs and the mlx libraries.
If CONFIG_RTE_BUILD_SHARED_LIB is enabled,
the mlx PMDs will embed ibverbs and the mlx libraries.

Support with meson may be added later.

85ee5dda6b net/dpaa2: change reference to private device
The I/O threads for DPAA2 take their reference for bpool ID, the
port ID and other info like qdid, from the rte_eth_dev. Further,
to get this data during I/O operation, a reference of the RTE
device is kept in the queue structure (dpaa2_queue).

In case of secondary processes, rte_eth_dev is not same as the
primary process. Thus, the reference goes invalid.

This patch changes the implementation to use the dev_private
rather than the rte_eth_dev as that is shared area across
all the processes.

109df4601c mempool/dpaa2: support saving context of buffer pool
Initial design was to have the buffer pool per process where a
global static array stores the bpids. But, in case of secondary
processes, this would not allow the I/O threads to translate the
bpid in Rx'd packets.

This patch moves the array to a global area (rte_malloc) and in
case of Rx thread not containing a valid reference to the array,
reference is build using the handle avaialble in the dpaa2_queue.

    1. disable notify

In case of reordering, virtio driver could read the flags on

the step 4, i.e. vhost will exit the loop on step 4 with
notifications enabled, but virtio will not notify.

sm_down is a boolean in order to check if the internal switch of the
fm10k is up or down. This variable is configured though an interrupt by
fm10k_dev_interrupt_handler_pf.

If sm_down is uninitialized, we are not sure of its value at the first
bring up. For example, if FM10K_EICR_SWITCHREADY is raised, the PMD will
try to reconfigure the switch, but it does not make sense, as it's the
first startup.

dc5a6e7422 net/ixgbe: fix over using multicast table for VF
According to the current implementation, all VFs will set bit
IXGBE_VMOLR_ROMPE during initialization, this cause any VF
will accept packets that match the MTA table. Since the MTA
table is shared by all VFs which means if one VF update MTA
table in function ixgbe_vf_set_multicast, then all other VFs
will receive multicast packets which cause unnecessary
performance overhead.

So it's better to set VF's ROPE bit of register VMOLR only
if multicast address filter is required on that VF.
Also, the ROPE bit should be reset when multicast address
filter is requested to clean.

This patch also aligns to the related fix on ixgbe
kernel driver 5.3.7.

7928b0fdf8 net/sfc: pass HW Tx queue index on creation
Software indexes are PMD internal and should not be passed outside.
Right now SW and HW indexes of the Tx queue match, so it is just
a cosmetic fix.

This capability is reported when supported by the current emitting
sub-device. Failsafe PMD itself does not exercise fast free logic.

8020573894 net/af_packet: fix setting MTU decrements sockaddr twice
When setting the MTU, eth_dev_mtu_set() is called to validate the
provided MTU. As part of that, it calculates the useful area to store
data and compares it against the MTU, to guarantee that there's enough
space to store the data. It calculates that as:
    "tp_frame_size - TPACKET2_HDRLEN - sizeof(struct sockaddr_ll)"

However, the TPACKET2_HDRLEN macro already increments sizeof(struct
sockaddr_ll) internally, meaning the useuful area of data above will
have sizeof(struct sockaddr_ll) decremented twice.

Instead, the useful area of data should be calculated as:
    "tp_frame_size - TPACKET2_HDRLEN"

This makes sure that there's enough useful area to fit the provided MTU
after excluding tpacket2_hdr and sockaddr_ll.
