common/mlx5: remove memory region dependency on Verbs

Replace 'struct ibv_mr *' (in 'struct mlx5_mr') with a new 'struct
mlx5_pmd_mr'.  The new struct contains the required MR field: lkey,

net/cxgbe: ignore flow default masks for unrequested fields

commit 536db938a444 ("net/cxgbe: add devargs to control filtermode and
filtermask") allows configuring hardware to select specific combination
of header fields to match in the incoming packets. However, the default
mask is set for all fields in the requested pattern items, even if the
field is not explicitly set in the combination and results in
validation errors. To prevent this, ignore setting the default masks
for the unrequested fields and the hardware will also ignore them in
validation, accordingly. Also, tweak the filter spec before finalizing
the masks.

ICE_AQC_REPORT_TOPO_CAP. This call uses the media

net/ice/base: reset capabilities before parsing

The capability flags used to report whether an NVM component has
a pending update are stored as simple booleans. If ice_parse_caps finds
the relevant capability then the boolean is set to true.

If the capability is not provided by firmware, then the boolean value
will be left alone. This works during initialization because the
capabilities structure is zero-initialized.

However, this does not work if capabilities are updated by calling
ice_get_caps again after driver load. For example, consider if firmware
had a pending update, and then an EMPR was triggered. The update will
complete, and firmware will no longer report these capabilities.

However, the device driver will have already set the pending flags.
After an EMPR, new capabilities are read. However, because the pending
flags in the dev_caps.common_cap structure have already been set, they
will remain true.

Fix this by clearing the capabilities structures in ice_parse_caps
before processing any capabilities.

This ensures that the capabilities structure will always be refreshed to
match the state of the device or function capabilities reported by
firmware.

net/ice/base: allow GENEVE and VXLAN rules with VLAN

When programming GENEVE and VXLAN switch rules, there are some instances
where both VLAN tagged packets plus non-VLAN tagged packets are needed
to match the rule.

In order to perform this action in one rule, the switch code needs
to setup the packet flag mask to ignore the VLAN packet flag. This
will allow the rule to match both VLAN and non-VLAN packets.

nanosecond timeval addition. This also ensures that the precision

This patch fixes it by passing '-ret' to the function strerror() when
ret is negative.

app/testpmd: fix error detection in MTU command

MTU is used in testpmd to set the maximum payload size for packets.
According to testpmd, the setting influence RX only.
In rte_ethdev there's no relation between MTU setting and JUMBO offload
or rx_max_pkt_len.

The previous fix in patch referenced below was meant to update the
correlated variables of max_pkt_len and JUMBO offload, but by doing so
it assumes that MTU setting can only exist when JUMBO offload supported
in the device. For example fail-safe device does supports set MTU and
doesn't support JUMBO offload, and in this case, though set MTU
succeeds, an error message is still printed since the JUMBO packet
offload is disabled.

The fix separates the two conditions to make sure the error
triggers only in case the set_mtu action actually failed.
