net: ena: Use tx_ring instead of xdp_ring for XDP channel TX
When an XDP program is loaded the existing channels in the driver split
into two halves:
- The first half of the channels contain RX and TX rings, these queues
are used for receiving traffic and sending packets originating from
kernel.
- The second half of the channels contain only a TX ring. These queues
are used for sending packets that were redirected using XDP_TX
or XDP_REDIRECT.
Referring to the queues in the second half of the channels as "xdp_ring"
can be confusing and may give the impression that ENA has the capability
to generate an additional special queue.
This patch ensures that the xdp_ring field is exclusively used to
describe the XDP TX queue that a specific RX queue needs to utilize when
forwarding packets with XDP TX and XDP REDIRECT, preserving the
integrity of the xdp_ring field in ena_ring.
