The ice workqueue doesn't seem to rely on any CPU locality and should
therefore be able to run on any CPU. In practice this is already
happening through the unbound ice_service_timer that may fire anywhere
and queue the workqueue accordingly to any CPU.

Add the following ring flag:
- IGB_RING_FLAG_TX_DISABLED (when xsk pool is being setup)
Add a xdp_buff array for use with XSK receive batch API, and a pointer
to xsk_pool in igb_adapter.
Add enable/disable functions for TX and RX rings.

Remove static qualifiers on the following functions to be able to call
from XSK specific file that is added in the later patches:
- igb_xdp_tx_queue_mapping()
- igb_xdp_ring_update_tail()
- igb_clean_tx_ring()
- igb_clean_rx_ring()
- igb_xdp_xmit_back()
- igb_process_skb_f
From: Sriram Yagnaraman
Add support for AF_XDP zero-copy transmit path.
A new TX buffer type IGB_TYPE_XSK is introduced to indicate that the Tx
frame was allocated from the xsk buff pool, so igb_clean_tx_ring() and
igb_clean_tx_irq() can clean the buffers correctly based on type.
igb_xmit_zc()
From: Sriram Yagnaraman
Add support for AF_XDP zero-copy receive path.
When AF_XDP zero-copy is enabled, the rx buffers are allocated from the
xsk buff pool using igb_alloc_rx_buffers_zc().
Use xsk_pool_get_rx_frame_size() to set SRRCTL rx buf size when zero-copy
is enabled.

This is version v7 of the AF_XDP zero-copy support for igb. Since Sriram's

real hardware, Intel i210 [1].

- Rebase to v6.12
- Collect tags

Introduce igb_xdp_is_enabled() to check if an XDP program is assigned to
the device. Use that wherever xdp_prog is read and evaluated.
