aee4a03fee net/mlx4: enhance Rx packet type offloads
This patch enhances the Rx packet type offload to also report the L4
protocol information in the hw ptype filled by the PMD for each received
packet.

b68d92b45c net/mlx4: fix HW memory optimizations careless
Volatilize all Rx/Tx HW negotiation memories to be sure no compiler
optimization prevents either load or store commands.

62e96ffb93 net/mlx4: fix no Rx interrupts
This commit addresses the issue of Rx interrupts support with
the new Rx datapath introduced in DPDK version 17.11.
In order to generate an Rx interrupt an event queue is armed with the
consumer index of the Rx completion queue. Since version 17.11 this
index is handled by the PMD so it is now the responsibility of the
PMD to write this value when enabling Rx interrupts.

096134582c net/mlx4: introducing consumer index mask
This commit defines MLX4_CQ_DB_CI_MASK which is used when updating
the consumer index of the completion queue instead of the hardcoded
0xffffff used until now.

9f57340a80 net/mlx4: restore Rx offloads
This patch adds hardware offloading support for IPV4, UDP and TCP checksum
verification, including inner/outer checksums on supported tunnel types.

It also restores packet type recognition support.

c3c977bbec net/mlx4: add Tx bypassing Verbs
Modify PMD to send single-buffer packets directly to the device
bypassing the Verbs Tx post and poll routines.

Tx gather support: add support for transmitting packets spanning
over multiple buffers.

Take into consideration the amount of entries a packet occupies
in the TxQ when setting the report-completion flag of the chip.
