The size of the receive completion ring should be recalculated
when MTU is increased to a size that requires scattered receive
or when LRO is enabled. Move logic for this calculation from
the ring configuration path to the device start path.
- Made size calculation dependent only on scattered_rx
status.
- Moved calculation of scattered_rx up in the initialization
sequence.
- Made LRO offload status part of scattered_rx calculation.
When the completion ring size is too small, completion overflows
can occur causing the ring to be disabled in hardware.

Previous fix used `rte_malloc_heap_socket_is_external()` to check if the

calling `rte_malloc_heap_socket_is_external()` will result in a

Fix it by replacing the API call with a check against maximum number of

There is the "set rxpkts" command in the testpmd interactive mode,
it configures the segment sizes to split the packet on receiving.
The mentioned segment sizes are provided on the Rx queue setup
as part of queue configuration. Hence, to take the rxpkts command

Before starting transmission of Tx burst, the driver checked the
available space in the sq and limited the number of packets for
transmission accordingly.
The calculation was incorrect for fragmented packets and potentially had
significantly limited the length of Tx bursts.
This patch removes the assessment and pushes packets to the sq as long
as the burst is not exhausted and space is available in the sq.
Correct evaluation of the required space isn't possible before the burst
because it depends on the number of segments of each packet.
This patch adds per-packet space evaluation for each packet before
attempting to process it. In case there is not enough queue space, the
burst will just stop without error.

When testing high performance numbers, it is often that CPU performance
limits the max values device can reach (both in pps and in gbps)
Here instead of recreating each packet separately, we use clones counter
to resend the same mbuf to the line multiple times.
PMDs handle that transparently due to reference counting inside of mbuf.
Reaching max PPS on small packet sizes helps here:

Tx-pps: 23642629 Tx-bps: 12105024112
Setting flowgen-clones to 512 pushes TX almost to our device

"port config all max-pkt-len" command fails because it doesn't set the

Commit in the fixes line moved the 'DEV_RX_OFFLOAD_JUMBO_FRAME' offload
flag update from 'cmd_config_max_pkt_len_parsed()' to 'init_config()'.
'init_config()' function is only called during testpmd startup, but the
flag status needs to be calculated whenever 'max_rx_pkt_len' changes.
The issue can be reproduced as [1], where the 'max-pkt-len' reduced and
'DEV_RX_OFFLOAD_JUMBO_FRAME' offload flag should be cleared but it
didn't.
Adding the 'update_jumbo_frame_offload()' helper function to update
'DEV_RX_OFFLOAD_JUMBO_FRAME' offload flag and 'max_rx_pkt_len'. This
function is called both by 'init_config()' and
'cmd_config_max_pkt_len_parsed()'.
Default 'max-pkt-len' value set to zero, 'update_jumbo_frame_offload()'
updates it to "RTE_ETHER_MTU + PMD specific Ethernet overhead" when it
is zero.
If '--max-pkt-len=N' argument provided, it will be used instead.
And with each "port config all max-pkt-len" command, the
'DEV_RX_OFFLOAD_JUMBO_FRAME' offload flag, 'max-pkt-len' and MTU is
updated.

For Kunpeng930, the NIC engine support 1280 tqps being taken over by
a PF. In this case, a maximum of 1281 interrupt resources are also
supported in this PF. To support the maximum number of queues, several
patches are made. But the interrupt related modification are missing.
So, in RX interrupt mode, a large number of queues will be aggregated
into one interrupt due to insufficient interrupts. It will lead to
waste of interrupt resources and reduces usability.
To utilize all these interrupt resources, related IMP command has been
extended. And, the I/O address of the extended interrupt resources are
different from the existing ones. So, a function used for calculating
the address offset has been added.
