Cover letter [PATCH v3 0/4] New RAW_PACKET QP type

The following patches add a new QP type named RAW_PACKET.

This type of QP is used in Ethernet environment and intended for creation of a whole packet, including L2 headers, from userspace. QP of thie type does not generate header in hardware but sending gathered payloads to the wire.
This QP type must be used only by privileged software.

Differences from V2

This series doesn't contain patch for protocol distinction. RAW_PACKET QP added to qp_state_table while preforming QP init. --
