net: ena: Always register RX queue info The RX queue info contains information about the RX queue which might be relevant to the kernel. To avoid configuring this queue for different scenarios, this patch moves the RX queue configuration to ena_up()/ena_down() function and makes it configured every interface state toggle.

net: ena: Don't check if XDP program is loaded in ena_xdp_execute() This check is already done in ena_clean_rx_irq() which indirectly calls it. This function is called in napi context and the driver doesn't allow to change the XDP program without performing destruction and reinitialization of napi context (part of ena_down/ena_up sequence).

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.

net: ena: Pass ena_adapter instead of net_device to ena_xmit_common() This change will enable the ability to use ena_xmit_common() in functions that don't have a net_device pointer. While it can be retrieved by dereferencing ena_adapter (adapter->netdev), there's no reason to do it in fast path code where this pointer is only needed for debug prints.

net: ena: Move XDP code to its new files XDP system has a very large footprint in the driver's overall code. makes the whole driver's code much harder to read. Moving XDP code to dedicated files. This patch doesn't make any changes to the code itself and only cut-pastes the code into ena_xdp.c and ena_xdp.h files so the change is purely cosmetic.
