mbuf: extend meaning of QinQ stripped bit

Certain hardware may be able to strip and/or save only the outermost
VLAN instead of both the VLANs in the mbuf in a QinQ scenario.
To handle such cases, we could re-interpret setting of just
PKT_RX_QINQ_STRIPPED to indicate that only the outermost VLAN has
been stripped and saved in mbuf->vlan_tci_outer.
Only When both PKT_RX_QINQ_STRIPPED and PKT_RX_VLAN_STRIPPED are set, the 2
VLANs have been stripped by the hardware and their TCI are saved in
mbuf->vlan_tci (inner) and mbuf->vlan_tci_outer (outer).

When the HW finishes to consume a burst of the guest Rx descriptors,
it creates a CQE in the CQ.

The mlx5 driver configured the kernel driver to send notification to
the guest callfd in the same time of the armed CQE event.
It means that the guest was notified only for each first CQE in a

available descriptors, the guest was not notified again for the rest

net/mlx4: fix premature disabling of interrupt

RXQ interrupts under Linux are based on the epoll mechanism. An
expected order of operations is as follows:
1. Call rte_eth_dev_rx_intr_enable(), to arm the CQ for receiving events
on data input.
2. Block on rte_epoll_wait() with an array of file descriptors
representing the CQ events. Upon data arrival the kernel will signal an
input event on the corresponding CQ fd.
3. Call rte_eth_dev_rx_intr_disable() after the event was received and
continue in polling mode. The mlx4 implementation of
rte_eth_dev_rx_intr_disable() is to get the CQ event and ack it.

In practice applications may wake up from rte_epoll_wait() due to
timeout with no event to ack but still call
rte_eth_dev_rx_intr_disable() unconditionally.  In such cases the call
should return EAGAIN (since the file descriptors are non-blocked), as
opposed to EINVAL which indicates a real failure.  In case of EAGAIN the
PMD should not warn on "unable to disable interrupt on rx queue".

net/iavf: disable simple XOR RSS hash function

Function simple_xor for AVF RSS is not required currently, thus we
just return rte_flow error when the command line has item simple_xor.

net/mlx5: optimize stack memory in probe

The device configuration struct is not small enough to be used as
function argument by value.

Call spawn function with device configuration by reference.

17 months agonet/mlx5: fix unnecessary init in mark conversion
Michael Baum [Tue, 21 Jul 2020 12:04:37 +0000 (12:04 +0000)]
net/mlx5: fix unnecessary init in mark conversion

The flow_dv_convert_action_mark function defines an array of
field_modify_info structures and initializes the first entity.

In the first entity id field, it initializes to 0, even though its type
is an enum that has no value of 0.
In fact, the function does not use this id field before assigning the
appropriate register id into it, so the initialization is unnecessary.
Moreover, this initialization is int into enum, and it would be better
not to create a type conflict for no reason.

Wait for the first entity initialization until the appropriate register
id is already known.
