Correct drop handling for XDP_TX on TX failure, were recently added in
commit 95357907ae73 ("mlx4: fix XDP_TX is acting like XDP_PASS on TX
ring full").
The change missed an opportunity for recycling the RX page, instead of
going through the page allocator, like the regular XDP_DROP action does.
This patch cease the opportunity, by going through the XDP_DROP case.

The VF link state can be changed via the 'ip link set' cmd.
Currently, the new link state does not take effect immediately.
The fix is for the PF to send a link change async event to the
designated VF after a VF link state change. This async event will
trigger the VF to update the link status.

After generating the random MAC address for VF, call the firmware to
approve it. This step serves 2 purposes. Some hypervisor (e.g. ESX)
wants to approve the MAC address. 2nd, the call will setup the
proper forwarding database in the internal switch.
We need to unlock the hwrm_cmd_lock mutex before calling bnxt_approve_mac().
We can do that because we are at the end of the function and all the
previous firmware response data has been copied.

The existing code is inconsistent in reporting and accepting the combined
channel count. bnxt_get_channels() reports maximum combined as the
maximum rx count. bnxt_set_channels() accepts combined count that
cannot be bigger than max rx or max tx.
For example, if max rx = 2 and max tx = 1, we report max supported
combined to be 2. But if the user tries to set combined to 2, it will
fail because 2 is bigger than max tx which is 1.
Fix the code to be consistent. Max allowed combined = max(max_rx, max_tx).
We will accept a combined channel count <= max(max_rx, max_tx).

The codes add ethtool functions to set RX flows for HW LRO. Because the
HW LRO hardware can only recognize the destination IP of TCP/IP RX flows,
the ethtool command to add HW LRO flow is as below:
ethtool -N [devname] flow-type tcp4 dst-ip [ip_addr] loc [0~1]
Otherwise, cause the hardware can set total four destination IPs, each
GMAC (GMAC1/GMAC2) can set two IPs separately at most.

The codes add the large receive offload (LRO) functions by hardware as below:
1) PDMA has total four RX rings that one is the normal ring, and others can
be configured as LRO rings.
2) Only TCP/IP RX flows can be offloaded. The hardware can set four IP
addresses at most, if the destination IP of the RX flow matches one of
them, it has the chance to be offloaded.
3) There three RX flows can be offloaded at most, and one flow is mapped to
one RX ring.
4) If there are more than three candidate RX flows, the hardware can
choose three of them by throughput comparison results.

The XDP_TX action can fail transmitting the frame in case the TX ring
is full or port is down. In case of TX failure it should drop the
frame, and not as now call 'break' which is the same as XDP_PASS.

Instead of reallocating and mapping pages for RX data-path,
recycle already used pages in a per ring cache.
Performance tests:
The following results were measured on a freshly booted system,
giving optimal baseline performance, as high-order pages are yet to
be fragmented and depleted.
We ran pktgen single-stream benchmarks, with iptables-raw-drop:
Single stride, 64 bytes:
* 4,739,057 - baseline
* 4,749,550 - order0 no cache
* 4,786,899 - order0 with cache
1% gain
Larger packets, no page cross, 1024 bytes:
* 3,982,361 - baseline
* 3,845,682 - order0 no cache
* 4,127,852 - order0 with cache
3.7% gain
Larger packets, every 3rd packet crosses a page, 1500 bytes:
* 3,731,189 - baseline
* 3,579,414 - order0 no cache
* 3,931,708 - order0 with cache
5.4% gain

To improve the memory consumption scheme, we omit the flow that
demands and splits high-order pages in Striding RQ, and stay
with a single Striding RQ flow that uses order-0 pages.
Moving to fragmented memory allows the use of larger MPWQEs,
which reduces the number of UMR posts and filler CQEs.
Moving to a single flow allows several optimizations that improve
performance, especially in production servers where we would
anyway fallback to order-0 allocations:
- inline functions that were called via function pointers.
- improve the UMR post process.
This patch alone is expected to give a slight performance reduction.
However, the new memory scheme gives the possibility to use a page-cache
of a fair size, that doesn't inflate the memory footprint, which will
dramatically fix the reduction and even give a performance gain.
Performance tests:
The following results were measured on a freshly booted system,
giving optimal baseline performance, as high-order pages are yet to
be fragmented and depleted.

struct mtk_eth has already contained struct regmap ethsys pointer
to the address range of the internal circuit reset, so we reuse it
to reset more internal blocks on ethernet hardware such as packet
processing engine (PPE) and frame engine (FE) instead of rstc which
deals with FE only.

1) original driver only resets DMA used by descriptor rings
which can't guarantee it can recover all various kinds of fatal
errors, so the patch tries to reset the underlying hardware
resource from scratch on Mediatek SoC required for ethernet
running, including power, pin mux control, clock and internal
circuits on the ethernet in order to restore into the initial
state which the rebooted machine gives.
2) add state variable inside structure mtk_eth to help distinguish
mtk_hw_init is called between the initialization during boot time
or re-initialization during the reset process.
3) add ge_mode variable inside structure mtk_mac for restoring
the interface mode of the current setup for the target MAC.
4) remove __init attribute from mtk_hw_init definition

the existing mtk_hw_init includes hardware and software
initialization inside so that it is slightly hard to reuse
them for the process of the reset recovery, so some splitting
is made here for keeping hardware initializing relevant thing
and the else such as IRQ registration and MDIO initialization
what are all about to the interface of core driver moved to the
other proper place because they have no needs to register IRQ and
re-initialize structure again during the reset process.
