Subject: [Intel-wired-lan] [PATCH iwl-next v5 08/13] idpf: prepare structures to
support XDP

From: Michal Kubiak <redacted>

Extend basic structures of the driver (e.g. 'idpf_vport', 'idpf_*_queue',
'idpf_vport_user_config_data') by adding members necessary to support XDP.
Add extra XDP Tx queues needed to support XDP_TX and XDP_REDIRECT
actions without interfering with regular Tx traffic.
Also add functions dedicated to support XDP initialization for Rx and Tx
queues and call those functions from the existing algorithms of queues
configuration.
