- The number of queues in a group must be a power of two.
- Queue indices must be consecutive, for instance the [0 1 2 3] set is
  allowed, however [3 2 1 0], [0 2 1 3] and [0 0 1 1 2 3 3 3] are not.
- The first queue of a group must be aligned to a multiple of the context
  size, e.g. if queues [0 1 2 3 4] are defined globally, allowed group
  combinations are [0 1] and [2 3]; groups [1 2] and [3 4] are not

net/mlx4: refactor flow item validation code

Since flow rule validation and creation have been refactored into a common
two-pass function, having separate callback functions to validate and
convert individual items seems redundant.

The purpose of these item validation functions is to reject partial masks
as those are not supported by hardware, before handing over the item to a
separate function that performs basic sanity checks.

The current approach and related code have the following issues:

- Lack of flow handle context in validation code requires kludges such as
  the special treatment reserved to spec-less Ethernet pattern items.
- Lack of useful error reporting; users need as much help as possible to
  understand what they did wrong, particularly when they hit hardware
  limitations that aren't mentioned by the flow API. Preventing them from
  going berserk after getting a generic "item not supported" message for no
  apparent reason is mandatory.
- Generic checks should be performed by the caller, not by item-specific
  validation functions.
- Mask checks either missing or too lax in some cases (Ethernet, VLAN).

This commit addresses all the above by combining validation and conversion
callbacks as "merge" callbacks that take an additional error context
parameter. Also:

- Support for source MAC address matching is removed as it has no effect.
- Providing an empty mask no longer bypasses the Ethernet specification
  check that causes a rule to become promiscuous-like.
- VLAN VIDs must be matched exactly, as matching all VLAN traffic while
  excluding non-VLAN traffic is not supported.

account the state of the device (whether it is started), trigger functions

to be 16 bytes long, regardless the length of the nonce,

Same happens with the AAD. It needs to be placed 18 bytes

to be multiple of 16 bytes long and all memory reserved

Lastly, nonce is not needed to be placed in the first 16 bytes

It works by first benchmarking crypto operation alloc-build-free

Results are shown as cycle counts per alloc/build/free, PMD enqueue
and PMD dequeue.

One new test mode is added: "pmd-cyclecount"
  (called with --ptest=pmd-cyclecount)

New command-line argument is also added:
  --pmd-cyclecount-delay-ms: this is a pmd-cyclecount-specific parameter
      that controls the delay between enqueue and dequeue. This is

6 years agocrypto/qat: enable Tx tail writes coalescing

crypto/qat: enable Tx tail writes coalescing

Don't write CSR tail until we processed enough TX descriptors.

To avoid crypto operations sitting in the TX ring indefinitely,
the "force write" threshold is used:
 - on TX, no tail write coalescing will occur if number of inflights
   is below force write threshold
 - on RX, check if we have a number of crypto ops enqueued that is
   below force write threshold that are not yet submitted to
   processing.
