app/testpmd: align behaviour of multi-port detach
A port can be closed in multiple situations:
- close command calling close_port() -> rte_eth_dev_close()
- exit calling close_port() -> rte_eth_dev_close()
- hotplug calling close_port() -> rte_eth_dev_close()
- hotplug calling detach_device() -> rte_dev_remove()
- port detach command, detach_device() -> rte_dev_remove()
- device detach command, detach_devargs() -> rte_eal_hotplug_remove()
The flow rules are flushed before each close.
It was already done in close_port(), detach_devargs() and
detach_port_device() which calls detach_device(),
but not in detach_device(). As a consequence, it was missing for siblings
of port detach command and unplugged device.
The check before calling port_flow_flush() is moved inside the function.
The state of the port to close is checked to be stopped.
As above, this check was missing in detach_device(),
impacting the cases of a multi-port device unplugged or detached
with the port detach command.

ethdev: remove old close behaviour
The temporary flag RTE_ETH_DEV_CLOSE_REMOVE is removed.
It was introduced in DPDK 18.11 in order to give time for PMDs to migrate.
The old behaviour was to free only queues when closing a port.
The new behaviour is calling rte_eth_dev_release_port() which does
three more tasks:
- trigger event callback
- reset state and few pointers
- free all generic port resources
The private port resources must be released in the .dev_close callback.
The .remove callback should:
- call .dev_close callback
- call rte_eth_dev_release_port()
- free multi-port device shared resources
Despite waiting two years, some drivers have not migrated,
so they may hit issues with the incompatible new behaviour.
After sending emails, adding logs, and announcing the deprecation,
the only last solution is to declare these drivers as unmaintained:
ionic, liquidio, nfp
Below is a summary of what to implement in those drivers.
* The freeing of private port resources must be moved
from the ".remove(device)" function to the ".dev_close(port)" function.
* If a generic resource (.mac_addrs or .hash_mac_addrs) cannot be freed,
it must be set to NULL in ".dev_close" function to protect from
subsequent rte_eth_dev_release_port() freeing.
* Note 1:
The generic resources are freed in rte_eth_dev_release_port(),
after ".dev_close" is called in rte_eth_dev_close(), but not when
calling ".dev_close" directly from the ".remove" PMD function.
That's why rte_eth_dev_release_port() must still be called explicitly
from ".remove(device)" after calling the ".dev_close" PMD function.
* Note 2:
If a device can have multiple ports, the common resources must be freed
only in the ".remove(device)" function.
* Note 3:
The port is supposed to be in a stopped state when it is closed.
If it is not the case, it is free to the PMD implementation
how to react when trying to close a non-stopped port:
either try to stop it automatically or just return an error.

ethdev: reset device and interrupt pointers on release
The pointers .device and .intr_handle were already reset by the helper
rte_eth_dev_pci_generic_remove().
It is now made part of rte_eth_dev_release_port().
It makes rte_eth_dev_pci_release() meaningless,
so it is replaced with a call to rte_eth_dev_release_port().

app/testpmd: fix displaying Rx/Tx queues information
Currently, the information of Rx/Tx queues from PMD driver is not
displayed exactly in the rxtx_config_display function. Because
"ports[pid].rx_conf" and "ports[pid].tx_conf" maintained in testpmd
application may be not the value actually used by PMD driver. For
instance, user does not set a field, but PMD driver has to use the
default value.
This patch fixes rxtx_config_display so that the information of Rx/Tx
queues can be really displayed for the PMD driver that implement
.rxq_info_get and .txq_info_get ops callback function.

app/testpmd: fix descriptor id check
The number of desc is a per queue configuration. But in the check
function, nb_txd & nb_rxd are used to check whether the desc_id is
valid. nb_txd & nb_rxd are the global configuration of number of desc.
If the queue configuration is changed by cmdline liks: "port config xx
txq xx ring_size xxx", the real value will be changed.
This patch use the real value to check whether the desc_id is valid.
And if these are not configured by user. It will use the default value
to check it, since the rte_eth_rx_queue_setup & rte_eth_tx_queue_setup
will use a default value to configure the queue if nb_rx_desc or
nb_tx_desc is zero.

app/testpmd: fix packet header in txonly mode
In txonly forward mode, the packet header is fixed by the initial
setting, including the packet length and checksum. So when the packets
varies, this may cause a packet header error. Currently, there are two
methods in txonly mode to randomly change the packets.
1. Set txsplit random and txpkts (x[,y]*), the number of segments
each packets will be a random value between 1 and total number of
segments determined by txpkts settings.
The step as follows:
a) ./testpmd -w xxx -l xx -n 4 -- -i --disable-device-start
b) port config 0 tx_offload multi_segs on
c) set fwd txonly
d) set txsplit rand
e) set txpkts 2048,2048,2048,2048
f) start
The nb_segs of the packets sent by testpmd will be 1~4. The real packet
length will be 2048, 4096, 6144 and 8192. But in fact the packet length
in ip header and udp header will be fixed by 8178 and 8158.
2. Set txonly-multi-flow. the ip address will be varied to generate
multiple flow.
The step as follows:
a) ./testpmd -w xxx -l xx -n 4 -- -i --txonly-multi-flow
b) set fwd txonly
c) start
The ip address of each pkts will change randomly, but since the header
is fixed, the checksum may be a error value.
Therefore, this patch adds a function to update the packet length and
check sum in the pkts header when the txsplit mode is set to rand or
multi-flow is set.

app/testpmd: remove restriction on Tx segments set
Currently, if nb_txd is not set, the txpkts is not allowed to be set
because the nb_txd is used to avoid the number of segments exceed the Tx
ring size and the default value of nb_txd is 0. And there is a bug that
nb_txd is the global configuration for Tx ring size and the ring size
could be changed by some command per queue. So these valid check is
unreliable and introduced unnecessary constraints.
This patch adds a valid check function to use the real Tx ring size to
check the validity of txpkts.
