Since commit e1ff9e82e2ea ("net: mptcp: improve fallback to TCP"),
when an MPTCP socket falls back to TCP, it can hit the TCP receive
fast-path, and delay or stop triggering the event notification.

Normally, if a reset fails due to failover or other communication error
there is another reset (eg: FAILOVER) in the queue and we would process
that reset. But if we are unable to communicate with PHYP or VIOS after
H_FREE_CRQ, there would be no other resets in the queue and the adapter
would be in an undefined state even though it was in the OPEN state
earlier. While starting the reset we set the carrier to off state so
we won't even get the timeout resets.
If the last queued reset fails, retry it as a hard reset (after the
usual 60 second settling time).

ptp: support virtual clocks and timestamping
Current PTP driver exposes one PTP device to user which binds network
interface/interfaces to provide timestamping. Actually we have a way
utilizing timecounter/cyclecounter to virtualize any number of PTP
clocks based on a same free running physical clock for using.
The purpose of having multiple PTP virtual clocks is for user space
to directly/easily use them for multiple domains synchronization.
user
space: ^ ^
| SO_TIMESTAMPING new flag: | Packets with
| SOF_TIMESTAMPING_BIND_PHC | TX/RX HW timestamps
v v
+--------------------------------------------+
sock: | sock (new member sk_bind_phc) |

v v
+--------------+--------------+--------------+
vclock: | ptp1 | ptp2 | ptpN |
+--------------+--------------+--------------+
pclock: | ptp0 free running |
+--------------------------------------------+
The block diagram may explain how it works. Besides the PTP virtual
clocks, the packet HW timestamp converting to the bound PHC is also
done in sock driver. For user space, PTP virtual clocks can be
created via sysfs, and extended SO_TIMESTAMPING API (new flag
SOF_TIMESTAMPING_BIND_PHC) can be used to bind one PTP virtual clock
for timestamping.
The test tool timestamping.c (together with linuxptp phc_ctl tool) can
be used to verify:

- Guranteed physical clock free running when using virtual
clocks.
