ethdev: deprecate hard-to-use or ambiguous items and actions

PF, VF and PHY_PORT require that applications have extra
knowledge of the underlying NIC and thus are hard to use.
Also, the corresponding items depend on the direction
attribute (ingress / egress), which complicates their
use in applications and interpretation in PMDs.

The concept of PORT_ID is ambiguous as it doesn't say whether
the port in question is an ethdev or the represented entity.

Items and actions PORT_REPRESENTOR, REPRESENTED_PORT
should be used instead.

(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.

3 years agonet/ixgbe: fix queue release
Julien Meunier [Tue, 28 Sep 2021 08:12:38 +0000 (10:12 +0200)]
net/ixgbe: fix queue release

On the vector implementation, during the tear-down, the mbufs not
drained in the RxQ and TxQ are freed based on an algorithm which
supposed that the number of descriptors is a power of 2 (max_desc).
Based on this hypothesis, this algorithm uses a bitmask in order to
detect an index overflow during the iteration, and to restart the loop
from 0.

However, there is no such power of 2 requirement in the ixgbe for the
number of descriptors in the RxQ / TxQ. The only requirement is to have
a number correctly aligned.

If a user requested to configure a number of descriptors which is not a
power of 2, as a consequence, during the tear-down, it was possible to
be in an infinite loop, and to never reach the exit loop condition.

By removing the bitmask and changing the loop method, we can avoid this
issue, and allow the user to configure a RxQ / TxQ which is not a power
of 2.

function interface to be able to specify the ingress m-port
flag for a representor RxQ. Rx prefix of packets on that queue
will contain ingress m-port field required for packet forwarding
in representor proxy.
