Merge branch 'dpaa_eth-add-xdp-support'
Camelia Groza says:
====================
dpaa_eth: add XDP support
Enable XDP support for the QorIQ DPAA1 platforms.
Implement all the current actions (DROP, ABORTED, PASS, TX, REDIRECT). No
Tx batching is added at this time.
Additional XDP_PACKET_HEADROOM bytes are reserved in each frame's headroom.
After transmit, a reference to the xdp_frame is saved in the buffer for
clean-up on confirmation in a newly created structure for software
annotations. DPAA_TX_PRIV_DATA_SIZE bytes are reserved in the buffer for
storing this structure and the XDP program is restricted from accessing
them.
The driver shares the egress frame queues used for XDP with the network
stack. The DPAA driver is a LLTX driver so no explicit locking is required
on transmission.
