8 years agonet/mlx5: handle Rx CQE compression
Nélio Laranjeiro [Fri, 24 Jun 2016 13:17:54 +0000 (15:17 +0200)]
net/mlx5: handle Rx CQE compression

Mini (compressed) completion queue entries (CQEs) are returned by the
NIC when PCI back pressure is detected, in which case the first CQE64
contains common packet information followed by a number of CQE8
providing the rest, followed by a matching number of empty CQE64
entries to be used by software for decompression.

Before decompression:

      0           1          2           6         7         8
  +-------+  +---------+ +-------+   +-------+ +-------+ +-------+
  | CQE64 |  |  CQE64  | | CQE64 |   | CQE64 | | CQE64 | | CQE64 |
  |-------|  |---------| |-------|   |-------| |-------| |-------|
  | ..... |  | cqe8[0] | |       | . |       | |       | | ..... |
  | ..... |  | cqe8[1] | |       | . |       | |       | | ..... |

  +-------+  +---------+ +-------+   +-------+ +-------+ +-------+

After decompression:

      0          1     ...     8
  +-------+  +-------+     +-------+
  | CQE64 |  | CQE64 |     | CQE64 |
  |-------|  |-------|     |-------|

  | ..... |  | ..... |  .  | ..... |
  | ..... |  | ..... |     | ..... |
  +-------+  +-------+     +-------+

This patch does not perform the entire decompression step as it would be
really expensive, instead the first CQE64 is consumed and an internal
context is maintained to interpret the following CQE8 entries directly.

Intermediate empty CQE64 entries are handed back to HW without further
processing.

net/enic: support scattered Rx

For performance reasons, this patch uses 2 VIC RQs per RQ presented to
DPDK.

The VIC requires that each descriptor be marked as either a start of
packet (SOP) descriptor or a non-SOP descriptor.  A one RQ solution
requires skipping descriptors when receiving small packets and results
in bad performance when receiving many small packets.

The 2 RQ solution makes use of the VIC feature that allows a receive
on primary queue to 'spill over' into another queue if the receive is
too large to fit in the buffer assigned to the descriptor on the
primary queue.  This means that there is no skipping of descriptors

net/bonding: inherit maximum Rx packet length

Instead of a hard-coded maximum receive length, allow the bonded interface
to inherit this limit from the slave interfaces.  This allows
an application that uses jumbo frames to pass realistic values to
rte_eth_dev_configure without causing an error.

Before the bonding interface is configured, allow slaves with any
max_rx_pktlen to be added and remember the lowest of these values as
a candidate value.  During dev_configure, set the bond device's
max_rx_pktlen to the candidate value.  After this point only slaves
with a max_rx_pktlen greater or equal to that of the bonding device
can be added.

If all slaves are removed, the bond device's pktlen is cleared.
