Reduce scope of mlx5e_ptp_params, move to its c file. Remove unneeded
variables from mlx5e_ptp_open and state bitmap from PTP channel. In
addition, remove channel index from PTP channel since it is set to a
hard coded value, use define instead.

Following patches in the set add support for RX PTP. Rename PTP prefix
from %s/port_ptp/ptp/g to include RX PTP too.
In addition rename indication (used in statistics context) that PTP-SQ
was opened: %s/port_ptp_opened/tx_ptp_opened/g. This will simplify adding
indication that PTP-RQ was opened.

Unify RQ creation for different RQ types. For each RQ type add a
separate open helper which initializes the RQ specific values and
trigger a call for generic open RQ function. Avoid passing the
mlx5e_channel pointer to the generic open RQ as a container, since the
RQ may reside under a different type of channel.

For interrupt mode INTM=0, TX/RX transfer complete will trigger signal
not only on sbd_perch_[tx|rx]_intr_o (Transmit/Receive Per Channel) but
also on the sbd_intr_o (Common).
As for multi-MSI implementation, setting interrupt mode INTM=1 is more
efficient as each TX intr and RX intr (TI/RI) will be handled by TX/RX ISR
without the need of calling the common MAC ISR.
Updated the TX/RX NORMAL interrupts status checking process as the
NIS status bit is not asserted for any RI/TI events for INTM=1.

stmmac_mac_interrupt() :- MAC (dev->irq), WOL (wol_irq), LPI (lpi_irq)
stmmac_safety_interrupt() :- Safety Feat Correctible Error (sfty_ce_irq)
& Uncorrectible Error (sfty_ue_irq)
stmmac_msi_intr_rx() :- For all RX MSI irq (rx_irq)
stmmac_msi_intr_tx() :- For all TX MSI irq (tx_irq)

In order to discover whether remote station supports frame preemption,
local station sends verify mPacket and expects response mPacket in
return from the remote station.
So, we add the functions to send and handle event when verify mPacket
and response mPacket are exchanged between the networked stations.
The mechanism to handle different FPE states between local and remote
station (link partner) is implemented using workqueue which starts a
task each time there is some sign of verify & response mPacket exchange
as check in FPE IRQ event. The task retries couple of times to try to
spot the states that both stations are ready to enter FPE ON. This allows
different end points to enable FPE at different time and verify-response
mPacket can happen asynchronously. Ultimately, the task will only turn
FPE ON when local station have both exchange response in both directions.
Thanks to Voon Weifeng for implementing the core functions for detecting
FPE events and send mPacket and phylink related change.

The kernel periodically checks the idle time of nexthop buckets to
determine if they are idle and can be re-populated with a new nexthop.
When the resilient nexthop group is offloaded to hardware, the kernel
will not see activity on nexthop buckets unless it is reported from
hardware.
Therefore, periodically (every 1 second) query the hardware for activity
of adjacency entries used as part of a resilient nexthop group and
report it to the nexthop code.
The activity is only queried if resilient nexthop groups are in use. The
delayed work is canceled otherwise.
