Implementation includes following limitations:
1) Packet's header length must be less than 256 (SFC_TSOH_STD_LEN);
2) Offset of the TCP header must be less than 208
(EF10_TCP_HEADER_OFFSET_LIMIT);
3) Number of Tx descriptors must be not less than number of descriptors
needed for TSO settings plus header plus one data segment.
If above conditions are not met, the packet is dropped.
If the maximum descriptor space is insufficient to hold entire TSO packet,
only a part of the packet is sent.

DPDK firmware variant supports equal stride super-buffer Rx mode which
provides higher packet rate and packet marks but requires dedicated
mempool manager with contiguous object block allocation (e.g. bucket).
Also the firmware supports subvariant without checksumming on Tx which
allows to reach higher packet rates on transmit if checksumming is not
required.

HW Rx descriptor represents many contiguous packet buffers which
follow each other. Number of buffers, stride and maximum DMA
length are setup-time configurable per Rx queue based on provided
mempool. The mempool must support contiguous block allocation and
get info API to retrieve number of objects in the block.

This provides the possibility to remove the dedicated

with the main log type. In order to keep these logs silent
by default, INFO level should be used.

Despite being versatile, the hardware support for filtering has a number
of special properties which must be taken into account. Namely, there is
a known set of valid filters which don't take any effect despite being
accepted by the hardware.
The combinations of match flags and field values which can describe the
exceptional filters are as follows:
- ETHER_TYPE or ETHER_TYPE | LOC_MAC with IPv4 or IPv6 EtherType
- ETHER_TYPE | IP_PROTO or ETHER_TYPE | IP_PROTO | LOC_MAC with UDP or
TCP IP protocol value
- The same combinations with OUTER_VID and/or INNER_VID
These exceptional filters can be expressed in terms of RTE flow rules.
If the user creates such a flow rule, no traffic will hit the underlying
filter, and no errors will be reported.
This patch adds a means to prevent such ineffective flow rules from
being created.
