uart_dev_ns8250 now relies on compatible property instead of additional
'busy-detect' cell. All drivers with compatible = "snps,dw-apb-uart" have
busy detection turned on. DTS files of devices affected by the change
were modified and 'busy-detect' property was removed.

Strict compatibility requirement is a root of problems when simplebus'
node has two compatibility strings (i.e. on Armada38x). Removing this
requirement should not interfere with other platforms.
fdt_is_compatible_strict() and fdt_find_compatible() calls were changed
in fdt_common.c and mv_common.c.

to actually wait until the TX FIFOs of UARTs have be drained before
returning. This is done by bringing the equivalent of the TS_BUSY flag
found in the previous implementation back in an ABI-preserving way.
Reported and tested by: Patrick Powell
Most likely, drivers for USB-serial-adapters likewise incorporating
TX FIFOs as well as other terminal devices that buffer output in some
form should also provide implementations of tsw_busy.

- Add optimizing LRO wrapper which pre-sorts all incoming packets
according to the hash type and flowid. This prevents exhaustion of
the LRO entries due to too many connections at the same time.
Testing using a larger number of higher bandwidth TCP connections
showed that the incoming ACK packet aggregation rate increased from
~1.3:1 to almost 3:1. Another test showed that for a number of TCP
connections greater than 16 per hardware receive ring, where 8 TCP
connections was the LRO active entry limit, there was a significant
improvement in throughput due to being able to fully aggregate more
than 8 TCP stream. For very few very high bandwidth TCP streams, the
optimizing LRO wrapper will add CPU usage instead of reducing CPU
usage. This is expected. Network drivers which want to use the
optimizing LRO wrapper needs to call "tcp_lro_queue_mbuf()" instead
of "tcp_lro_rx()" and "tcp_lro_flush_all()" instead of
"tcp_lro_flush()". Further the LRO control structure must be
initialized using "tcp_lro_init_args()" passing a non-zero number
into the "lro_mbufs" argument.
- Make LRO statistics 64-bit. Previously 32-bit integers were used for
statistics which can be prone to wrap-around. Fix this while at it
and update all SYSCTL's which expose LRO statistics.
- Ensure all data is freed when destroying a LRO control structures,
especially leftover LRO entries.
- Reduce number of memory allocations needed when setting up a LRO
control structure by precomputing the total amount of memory needed.
- Add own memory allocation counter for LRO.
- Bump the FreeBSD version to force recompilation of all KLDs due to
change of the LRO control structure size.

The dynamic config on Medford is stored using two partitions in flash, and at
any time one is the 'current' partition, used to provide the active config,
and the other 'backup' partition is used for writes. This means that there
are two potential partitions that can be used to service reads, and which is
required can depend on, for example, whether the read is to get the current
contents or to verify a write.
When the partition write lock is held, the default behaviour is to read from
the backup partition, which was wrong for most reads in the common code which
require the current partition. This change allows the current partition to be
read whilst the write lock is held.
There is one read in Manftest which needs the backup partition.
ef10_nvram_partn_read_mode() is created to avoid changing
ef10_nvram_partn_read() which shares a prototype with the equivalent Falcon
and Siena methods.
MC_CMD_NVRAM_READ_IN_V2 adds an extra field, but firmware which doesn't support
it just ignores it.

we want to use it.
The rate table was being initialised in low->high, but the link quality
table was being initialised high->low. So, when we did a lookup, we
would get the indexes wrong.
This started by a patch from dragonflybsd which reversed how the ni->in_ridx[]
array is being used; I'd rather it all be consistent. So, this is consistent.

Previously the polarity was for TTL levels, which are the reverse of RS-232.
Also add handling of the UART_PPS_INVERT_PULSE option bit in the sysctl
value, the same as was recently added to uart(4), so that people using TTL
level connections can request a logical inverting of the signal.
Use the named constants from the new dev/uart/uart_ppstypes.h for the pps

Fix efx_vpd_hunk_next() which has -- since its inception -- failed to
correctly iterate over the tags and keywords contained in the VPD data.
Only the first tag or keyword would be returned and the next call with
*contp == 1 would walk to the end of the data and finish.
This was spotted when fixing up errors spotted by Prefast code analysis
(which neglected to set all of the out parameters in all successful cases)
Also fix efx_vpd_verify() on Siena and EF10 which (as a side effect of
correctly iterating over all the tags and keywords) was failing as it
detected that both the static VPD and dynamic VPD storage contained an
RV keyword in the VPD-R tag. This is intentional as the static VPD and
dynamic VPD are stored separately (firmware merges their contents and
computes a new RV keyword checksum for the data readable from the VPD
capability in PCIe configuration space).
