net: ena: Add support to changing tx_push_buf_len
The ENA driver allows for two distinct values for the number of bytes of the packet's payload that can be written directly to the device.
For a value of 224 the driver turns on Large LLQ Header mode in which the first 224 of the packet's payload are written to the LLQ.

net: ena: add device distinct log prefix to files
ENA logs are adjusted to display the full ENA representation to distinct each ENA device in case of multiple interfaces. Using netdev_err/warn and dev_info functions for logging provides uniform printing with clear distinction of the device and interface.
This patch changes all printing in ena_com files to use netev_* logging functions except for messages of info level. Log functions of that level would be printed with dev_info because of the early stage they are called in when net_device struct isn't yet registered.
To allow using netdev_* functions in all ena_com functions, a pointer to the net_device was added to ena_com_dev struct.
The patch also adds some log messages to make driver debugging easier.

net: ena: support new LLQ acceleration mode
New devices add a new hardware acceleration engine, which adds some restrictions to the driver. Metadata descriptor must be present for each packet and the maximum burst size between two doorbells is now limited to a number advertised by the device.
This patch adds: 1. A handshake protocol between the driver and the device, so the device will enable the accelerated queues only when both sides support it.
2. The driver support for the new acceleration engine: 2.1. Send metadata descriptor for each Tx packet. 2.2. Limit the number of packets sent between doorbells.(*)
(*) A previous driver implementation of this feature was comitted in commit 05d62ca218f8 ("net: ena: add handling of llq max tx burst size") however the design of the interface between the driver and device changed since then. This change is reflected in this commit.

net: ena: add handling of llq max tx burst size
There is a maximum TX burst size that the ENA device can handle. It is exposed by the device to the driver and the driver needs to comply with it to avoid bugs.
In this commit we: 1. Add ena_com_is_doorbell_needed(), which calculates the number of llq entries that will be used to hold a packet, and will return true if they exceed the number of allowed entries in a burst. If the function returns true, a doorbell needs to be invoked to send this packet in the next burst.
2. Follow the available entries in the current burst: - Every doorbell a new burst begins - With each write of an llq entry, the available entries in the current burst are decreased by 1.

net: ena: fix incorrect usage of memory barriers
Added memory barriers where they were missing to support multiple architectures, and removed redundant ones.
As part of removing the redundant memory barriers and improving performance, we moved to more relaxed versions of memory barriers, as well as to the more relaxed version of writel - writel_relaxed, while maintaining correctness.

net: ena: Eliminate duplicate barriers on weakly-ordered archs
Code includes barrier() followed by writel(). writel() already has a barrier on some architectures like arm64.
This ends up CPU observing two barriers back to back before executing the register write.
Create a new wrapper function with relaxed write operator. Use the new wrapper when a write is following a barrier().
Since code already has an explicit barrier call, changing writel() to writel_relaxed() and adding mmiowb() for ordering protection.

A mechanism for detection of stuck Rx/Tx rings due to missed or misrouted interrupts. Check if there are unhandled completion descriptors before the first MSI-X interrupt arrived. The check is per queue and per interrupt vector. Once such condition is detected, driver and device reset is scheduled.
