Implement set/get functions to configure PFC stall prevention
timeout by tunables api through ethtool.
By default the stall prevention timeout is configured to 8 sec.
Timeout range is: 80-8000 msec.
Enabling stall prevention with the auto timeout will set
the timeout to 100 msec.

spectrum_router and spectrum_mr have several APIs that are used to
manipulate configurations originating from ipmr fib notifications.
Following previous patches all the protocol-specifics that are necessary
for the configuration are hidden within spectrum_mr. This allows us to
clean the API and make sure that other than choosing the mr_table based
on the fib notification family, spectrum_router wouldn't care about the
source of the notification when passing it onward to spectrum_mr.
This would later allow us to leverage the same code for fib
notifications originating from ip6mr.

Current multicast routing logic in driver assumes it's always meant to
deal with IPv4 multicast routes, leaving several placeholders for
later IPv6 support [currently usually WARN()].
This patch changes the driver's internal multicast route struct into
holding a common mr_mfc instead of the IPv4 mfc_cache.
The various placeholders are grouped into 2:
- Functions that require only the common bits; These remain and the
restriction for IPv4-only is lifted.
- Function that require IPv4-specifics - for handling these functions
we add sets of operations that encapsulate the protocol differences

A step toward offloading IPv6 routing, this adds an additional

region] and populates the default rule for IPv6 multicast packets.
