mlx5 HW can't perform IPsec offload operation simultaneously both on PF
and VFs at the same time. While the previous patches added devlink knobs
to change IPsec capabilities dynamically, there is a need to add a logic
to block such IPsec capabilities for the cases when IPsec is already
configured.

In the commit 366e46242b8e ("net/mlx5e: Make IPsec offload work together
with eswitch and TC"), new API to block IPsec vs. TC creation was introduced.
Internally, that API used devlink lock to avoid races with userspace, but it is
not really needed as dev->priv.eswitch is stable and can't be changed. So remove
dependency on devlink lock and move block encap code back to its original place.

The code is duplicated to perform the copy twice -- to handle buffer
wrap-around. Instead of the duplication, roll this into the loop.
(And add some blank lines around to have the code a bit more readable.)

Some count types are already 'size_t' for a long time. Some were
switched to 'size_t' recently. Unify the rest with those now.
This allows for some min_t()s to become min()s. And make one min()
an explicit min_t() as we are comparing signed 'room' to unsigned
'count'.

The jiffies tests in n_tty_receive_overrun() are simplified ratelimiting
(without locking). We could use struct ratelimit_state and the helpers,
but to me, it occurs to be too complex for this use case.
But the code currently tests both if the time passed (the first
time_after()) and if jiffies wrapped around (the second time_after()).
time_is_before_jiffies() takes care of both, provided overrun_time is
initialized at the allocation time.
So switch to time_is_before_jiffies(), the same what ratelimiting does.

For AM65x SR2.0 it's required to enable IEP1 in raw 64bit mode which is
used by PRU FW to monitor the link and apply w/a for 10M link issue.
Note. No public errata available yet.
Without this w/a the PRU FW will stuck if link state changes under TX
traffic pressure.
Hence, add support for 10M full duplex for AM65x SR2.0:
- add new IEP API to enable IEP, but without PTP support
- add pdata quirk_10m_link_issue to enable 10M link issue w/a.

Add packet timestamping TS and PTP PHC clock support.
For AM65x and AM64x:
- IEP1 is not used
- IEP0 is configured in shadow mode with 1ms cycle and shared between
Linux and FW. It provides time and TS in number cycles, so special
conversation in ns is required.
- IEP0 shared between PRUeth ports.
- IEP0 supports PPS, periodic output.
- IEP0 settime() and enabling PPS required FW interraction.
- RX TS provided with each packet in CPPI5 descriptor.
- TX TS returned through separate ICSSG hw queues for each port. TX TS
readiness is signaled by INTC IRQ. Only one packet at time can be requested
for TX TS.

For transfers below 4K, let's use iATU since using eDMA for such small
transfers is inefficient.
This is mainly because setting up an eDMA transfer and waiting for
completion adds some latency. This latency is negligible for large
transfers but not for the smaller ones.
With using iATU, there is an increase in ~50Mbps throughput on both MHI
UL (Uplink) and DL (Downlink) channels.

For differentiating the iATU and eDMA APIs, the pci_epf_mhi_{read/write}

specific APIs pci_epf_mhi_edma_{read/write} are introduced.

Qualcomm PCIe Endpoint controllers have the in-built Embedded DMA (eDMA)
peripheral for offloading the data transfer between the PCIe bus and

Let's add support for it by enabling the eDMA IRQ in the driver. The

Since the eDMA on Qualcomm platforms only uses a single IRQ for all
channels, use 1 for edma.nr_irqs.
