In D3 suspend flow in 9260 gen2 HW, the NIC receives two PERST signals.
The first PERST is expected and indicates the device on coming resume flow.
The second PERST causes FW restart FW restart.
In order to avoid this issue, the FW set the persistence bit on.
Once this bit is set, the FW ignores reset attempts.
The problem is when the FW gets assert during D3 and then the persistence
bit is set and causes the FW to ignore reset.
To handle this issue, the FW opens the preg bit which allows access
to the persistence bit, so that the driver clear the persistence bit
and reset the NIC.
The flow is as follows:
the driver checks if the persistence bit is set.
If the bit is set, the driver checks if he can clear the bit.
If the driver can not clear the bit then there is no point to continue
configuring the NIC since it will fail.
The fix was added is in start HW flow instead of the resume flow since in
general, if the persistence bit is set, the driver can not start the FW.
So it is good to check it when we start configuring the NIC.
The driver does not need to close the preg bit since the FW close it
during the start flow.

All the queue management code runs under mvm->mutex, so there are
only very few cases of accessing the data structures without it:
* TX path, which doesn't take any locks anyway
* iwl_mvm_wake_sw_queue() and iwl_mvm_stop_sw_queue() where we
just (atomically) read a bitmap, so the lock isn't needed.
Therefore, we can remove the spinlock. This enables some cleanup

Instead of direct SKB list pointer accesses.
The loops in this function had to be rewritten to accommodate this
more easily.
The first loop iterates now over the target list in the outer loop,
and triggers an mmc data operation when the per-operation limits are
hit.
Then after the loops, if we have any residue, we trigger the last
and final operation.
For the page aligned workaround, where we have to copy the read data
back into the original list of SKBs, we use a two-tiered loop. The
outer loop stays the same and iterates over pktlist, and then we have
an inner loop which uses skb_peek_next(). The break logic has been
simplified because we know that the aggregate length of the SKBs in
the source and destination lists are the same.
This change also ends up fixing a bug, having to do with the
maintainance of the seg_sz variable and how it drove the outermost
loop. It begins as:
seg_sz = target_list->qlen;
ie. the number of packets in the target_list queue. The loop
structure was then:
while (seq_sz) {
...
while (not at end of target_list) {
...
sg_cnt++
...
}
...
seg_sz -= sg_cnt;
The assumption built into that last statement is that sg_cnt counts
how many packets from target_list have been fully processed by the
inner loop. But this not true.
If we hit one of the limits, such as the max segment size or the max
request size, we will break and copy a partial packet then contine
back up to the top of the outermost loop.
With the new loops we don't have this problem as we don't guard the
loop exit with a packet count, but instead use the progression of the
pkt_next SKB through the list to the end. The general structure is:
sg_cnt = 0;
skb_queue_walk(target_list, pkt_next) {
pkt_offset = 0;
...
sg_cnt++;
...
while (pkt_offset < pkt_next->len) {
pkt_offset += sg_data_size;
if (queued up max per request)
mmc_submit_one();
}
}
if (sg_cnt)
mmc_submit_one();
The variables that maintain where we are in the MMC command state such
as req_sz, sg_cnt, and sgl are reset when we emit one of these full
sized requests.

The kernel functions to prepare verifier and translate for offloaded
program retrieve "offload" from "prog", and "netdev" from "offload".
Then both "prog" and "netdev" are passed to the callbacks.

from the offload object attached to prog - if they need it at all. There
is currently no need to pass the netdev as an argument to those

For passing device functions for offloaded eBPF programs, there used to
be no place where to store the pointer without making the non-offloaded
programs pay a memory price.
As a consequence, three functions were called with ndo_bpf() through
specific commands. Now that we have struct bpf_offload_dev, and since
none of those operations rely on RTNL, we can turn these three commands
into hooks inside the struct bpf_prog_offload_ops, and pass them as part
of bpf_offload_dev_create().
This commit effectively passes a pointer to the struct to
bpf_offload_dev_create(). We temporarily have two struct
bpf_prog_offload_ops instances, one under offdev->ops and one under
offload->dev_ops. The next patches will make the transition towards the
former, so that offload->dev_ops can be removed, and callbacks relying
on ndo_bpf() added to offdev->ops as well.
While at it, rename "nfp_bpf_analyzer_ops" as "nfp_bpf_dev_ops" (and
similarly for netdevsim).

after receiving the IMP reset interrupt.
2. The driver needs to notify the hardware to reload the IMP firmware.
3. The IMP firmware reloading makes the reset time of hardware longer,
so it is necessary to extend the driver's waiting time to wait for
the hardware reset to complete.
4. In hclge_check_event_cause, IMP reset event should have higher
priority than other events.

2. The PF/VF driver needs to down the netdev within 100 ms and then wait
