net/i40e: fix risk in descriptor read in NEON Rx

Rx descriptor is 16B/32B in size. If the DD bit is set, it indicates
that the rest of the descriptor words have valid values. Hence, the
word containing DD bit must be read first before reading the rest of
the descriptor words.

In NEON vector PMD, vector load loads two contiguous 8B of
descriptor data into vector register. Given vector load ensures no
16B atomicity, read of the word that includes DD field could be
reordered after read of other words. In this case, some words could
contain invalid data.

Read barrier is added after read of qword1 that includes DD field.
And qword0 is reloaded to update vector register. This ensures
that the fetched data is correct.

net/ena: fix offload capabilities verification

ENA PMD has multiple checksum offload flags, which are more discrete
than the DPDK offload capabilities flags.
As the driver wasn't storing it's internal checksum offload capabilities
and was relying only on the DPDK capabilities, not all scenarios could
be properly covered (like when to prepare pseudo header checksum and
when not).

Moreover, the user could request offload capability, which isn't
supported by the HW and the PMD would quietly ignore the issue.

This commit reworks eth_ena_prep_pkts() function to perform additional
checks and to properly reflect the HW requirements. With the
RTE_LIBRTE_ETHDEV_DEBUG enabled, the function will do even more
verifications, to help the user find any issues with the mbuf
configuration.

3 years agoethdev: fix max Rx packet length
Ferruh Yigit [Mon, 18 Oct 2021 13:48:48 +0000 (14:48 +0100)]
ethdev: fix max Rx packet length

There is a confusion on setting max Rx packet length, this patch aims to
clarify it.

'rte_eth_dev_configure()' API accepts max Rx packet size via
'uint32_t max_rx_pkt_len' field of the config struct 'struct
rte_eth_conf'.

Also 'rte_eth_dev_set_mtu()' API can be used to set the MTU, and result
stored into '(struct rte_eth_dev)->data->mtu'.

These two APIs are related but they work in a disconnected way, they
store the set values in different variables which makes hard to figure
out which one to use, also having two different method for a related
functionality is confusing for the users.

Other issues causing confusion is:
* maximum transmission unit (MTU) is payload of the Ethernet frame. And
  'max_rx_pkt_len' is the size of the Ethernet frame. Difference is
  Ethernet frame overhead, and this overhead may be different from
  device to device based on what device supports, like VLAN and QinQ.
* 'max_rx_pkt_len' is only valid when application requested jumbo frame,
  which adds additional confusion and some APIs and PMDs already
  discards this documented behavior.
* For the jumbo frame enabled case, 'max_rx_pkt_len' is an mandatory
  field, this adds configuration complexity for application.

As solution, both APIs gets MTU as parameter, and both saves the result
in same variable '(struct rte_eth_dev)->data->mtu'. For this
'max_rx_pkt_len' updated as 'mtu', and it is always valid independent
from jumbo frame.

For 'rte_eth_dev_configure()', 'dev->data->dev_conf.rxmode.mtu' is user
request and it should be used only within configure function and result
should be stored to '(struct rte_eth_dev)->data->mtu'. After that point
both application and PMD uses MTU from this variable.

When application doesn't provide an MTU during 'rte_eth_dev_configure()'
default 'RTE_ETHER_MTU' value is used.

Additional clarification done on scattered Rx configuration, in
relation to MTU and Rx buffer size.
MTU is used to configure the device for physical Rx/Tx size limitation,
Rx buffer is where to store Rx packets, many PMDs use mbuf data buffer
size as Rx buffer size.
PMDs compare MTU against Rx buffer size to decide enabling scattered Rx
or not. If scattered Rx is not supported by device, MTU bigger than Rx
buffer size should fail.

data into private header (ethdev_driver.h).
Few minor changes to keep DPDK building after that.

ethdev: copy fast-path API into separate structure

Copy public function pointers (rx_pkt_burst(), etc.) and related
pointers to internal data from rte_eth_dev structure into a
separate flat array. That array will remain in a public header.
The intention here is to make rte_eth_dev and related structures internal.
That should allow future possible changes to core eth_dev structures
to be transparent to the user and help to avoid ABI/API breakages.
The plan is to keep minimal part of data from rte_eth_dev public,
so we still can use inline functions for fast-path calls
(like rte_eth_rx_burst(), etc.) to avoid/minimize slowdown.
The whole idea beyond this new schema:
1. PMDs keep to setup fast-path function pointers and related data
   inside rte_eth_dev struct in the same way they did it before.
2. Inside rte_eth_dev_start() and inside rte_eth_dev_probing_finish()
   (for secondary process) we call eth_dev_fp_ops_setup, which
   copies these function and data pointers into rte_eth_fp_ops[port_id].
3. Inside rte_eth_dev_stop() and inside rte_eth_dev_release_port()
   we call eth_dev_fp_ops_reset(), which resets rte_eth_fp_ops[port_id]
   into some dummy values.
4. fast-path ethdev API (rte_eth_rx_burst(), etc.) will use that new
   flat array to call PMD specific functions.
That approach should allow us to make rte_eth_devices[] private
without introducing regression and help to avoid changes in drivers code.

ethdev: change input parameters for Rx queue count

rte_eth_rx_queue_count().
