The fix in commit 028e045da93b7c1c26417e80e4b4e388b86a713d was incorrect as
it can cause the right edge of the window to shrink when we announce
a zero window due to receive buffer being full as its done before the check
for seeing if the window is being shrunk because of the selected window.
Further the window was calculated purely on available space but in cases where
we are getting full sized segments it makes more sense to use the actual bytes
being held. This CL changes to use the lower of the total available space vs
the available space in the maximal window we could advertise minus the actual
payload bytes being held.
This change also cleans up the code so that the window selection logic is
not duplicated between getSendParams() and windowCrossedACKThresholdLocked.

RACK detects packet reordering by checking if the sender received ACK for
the packet which has the sequence number less than the already acknowledged
packets.

Add parser and formatting for golang benchmarks for docker benchmarks.
Change adds a library for printing and parsing Test parameters and metrics.
Benchmarks use the library to print parameters in the Benchmark title
(e.g. the name field in b.Run()), and to report CustomMetrics. Parser
uses the library to parse printed data from benchmark output and
put it into BigQuery structs.

- sysinfo(2) does not actually require a fine-grained breakdown of memory
usage. Accordingly, instead of calling pgalloc.MemoryFile.UpdateUsage() to
update the sentry's fine-grained memory accounting snapshot, just use
pgalloc.MemoryFile.TotalUsage() (which is a single fstat(), and therefore far
cheaper).
- Use the number of threads in the root PID namespace (i.e. globally) rather
than in the task's PID namespace for consistency with Linux (which just reads
global variable nr_threads), and add a new method to kernel.PIDNamespace to
allow this to be read directly from an underlying map rather than requiring
the allocation and population of an intermediate slice.

When a completed entry exists for a neighbor, there is no need to block
while reachability is (re)confirmed. The stack should continue to use
the neighbor's link address while NUD is performed.

When a response needs to be sent to an incoming packet, the stack should
consult its neighbour table to determine the remote address's link
address.
When an entry does not exist in the stack's neighbor table, the stack
should queue the packet while link resolution completes. See comments.

When the neighbor table already has link address for a neighbor but is
trying to confirm reachability, it may send unicast probes to the
neighbor.

the correct value needed is 0xbbff440c0400 but the const
defined is 0x000000000000ffc0 due to the operator error
in _MT_EL1_INIT, both kernel and user space memory
attribute should be Normal memory not DEVICE_nGnRE

It was originally set to 30s for IPv6 (same as IPv4) but this is not
what RFC 8200 prescibes. Linux also defaults to 60s [1].
