On emulation systems, the EMAC's internal PHY ("SGMII") is not present, but is not needed for network functionality. So just display a warning message and ignore the SGMII.

On ACPI systems, the driver depends on firmware pre-initializing the EMAC because we don't have access to the clocks, and the EMAC has specific clock programming requirements. Therefore, we don't want to reset the EMAC while we are completing the initialization.

We were using t4_get_mps_bg_map() for both t4_get_port_stats() to determine which MPS Buffer Groups to report statistics on for a given Port, and also for t4_sge_alloc_rxq() to provide a TP Ingress Channel Congestion Map. For T4/T5 these are actually the same values (because they are ~somewhat~ related), but for T6 they should return different values (T6 has Port 0 associated with MPS Buffer Group 0 (with MPS Buffer Group 1 silently cascading off) and Port 1 is associated with MPS Buffer Group 2 (with 3 cascading off)).

Current driver tries to allocate msix vectors as the number of the negotiated io queues. (with another msix vector for management). If pci_alloc_irq_vectors() fails, the driver aborts the probe and the ENA network device is never brought up. With this patch, the driver's logic will reduce the number of IO queues to the number of allocated msix vectors (minus one for management) instead of failing probe().

ENA driver post Rx buffers through the Rx submission queue for the ENA device to fill them with receive packets. Each Rx buffer is marked with req_id in the Rx descriptor. Newer ENA devices could consume the posted Rx buffer in out of order, and as result the corresponding Rx completion queue will have Rx completion descriptors with non contiguous req_id(s) In this change the driver holds two rings. The first ring (called free_rx_ids) is a mapping ring. It holds all the unused request ids. The values in this ring are from 0 to ring_size -1. When the driver wants to allocate a new Rx buffer it uses the head of free_rx_ids and uses it's value as the index for rx_buffer_info ring. The req_id is also written to the Rx descriptor Upon Rx completion, The driver took the req_id from the completion descriptor and uses it as index in rx_buffer_info. The req_id is then return to the free_rx_ids ring. This patch also adds statistics to inform when the driver receive out of range or unused req_id. Note: free_rx_ids is only accessible from the napi handler, so no locking is required Signed-off-by: NNetanel Belgazal <netanel@amazon.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

DRV_MODE means that user space wants the program to be run in the driver. Do not try to offload. Only offload if no mode flags have been specified. Remember what the mode is when the program is installed and refuse new setup requests if there is already a program loaded in a different mode. This should leave it open for us to implement simultaneous loading of two programs - one in the drv path and another to the NIC later.

In preparation of XDP offload flags move the driver setup into a function. Otherwise the number of conditions in one function would make it slightly hard to follow.
