Now that software UFO is supported, UFO can be enabled on master
devices like bridge, bond even though the attached device doesn't
support this feature in hardware.
This allows UFO to be used between KVM host and guest even when a
physical interface attached to the bridge doesn't support UFO.

UDP_HTABLE_SIZE was initialy defined to 128, which is a bit small for
several setups.
4000 active UDP sockets -> 32 sockets per chain in average. An
incoming frame has to lookup all sockets to find best match, so long
chains hurt latency.
Instead of a fixed size hash table that cant be perfect for every
needs, let UDP stack choose its table size at boot time like tcp/ip
route, using alloc_large_system_hash() helper
Add an optional boot parameter, uhash_entries=x so that an admin can
force a size between 256 and 65536 if needed, like thash_entries and
rhash_entries.
dmesg logs two new lines :
[ 0.647039] UDP hash table entries: 512 (order: 0, 4096 bytes)
[ 0.647099] UDP Lite hash table entries: 512 (order: 0, 4096 bytes)
Maximal size on 64bit arches would be 65536 slots, ie 1 MBytes for non
debugging spinlocks.

Then, it is unconditionally set to new_active, without being used in between.
The first assignment, having no side effect, is useless.

I'm only seeing this on x86_64 systems, not on 32-bit with same

This removes a redundancy in the CCID half-connection (hc) naming scheme:
* instead of 'hctx->tx_...', write 'hc->tx_...';
* instead of 'hcrx->rx_...', write 'hc->rx_...';
which works because the 'type' of the half-connection is encoded in the
'rx_' / 'tx_' prefixes.

This patch starts a less problematic naming convention for CCID structs.
The old naming convention used 'hc{tx,rx}->ccid?hc{tx,rx}->...' as
recurring prefixes, which made the code
* hard to write (not easy to fit into 80 characters);
* hard to read (most of the space is occupied by prefixes).
The new naming scheme:
* struct entries for the TX socket are prefixed by 'tx_';
* and those for the RX socket are prefixed by 'rx_'.
The identifiers then remain distinguishable when grep-ing through the tree:
(a) RX/TX sockets are distinguished by the naming scheme,
(b) individual CCIDs are distinguished by filename (ccid{2,3,4}.{c,h}).
This first patch implements the scheme for CCID-2.

Both 1000 & 6000 series NICs contain on-chip OTP memory that
replaces the off-chip EEPROM memory. The nature of OTP means
there is a limited number of times a particular board can go through the
factory flow and be (re)calibrated. As a consequence there will be some boards
that contain EEPROM memory because OTP blocks were full.
In the signature validation routine, iwlwifi needs to make sure
"select bit" and "EEPROM/OTP signature" agree on the type of
NVM to be used to configure the system.

The iwlwifi drivers have LED blinking requirements that
mac80211 cannot fulfill due to the use of just a single
LED instead of different ones for TX, RX, radio etc.
Instead, the single LED blinks according to transfers
and is solid on the rest of the time. As such, having
LED class devices registered that mac80211 triggers are
connected to is pointless as we don't use the triggers
anyway.
Remove all the useless code and add hooks into the
driver itself. At the same time, make the LED code
abstracted so the core code that determines blink rate
etc. can be shared between 3945 and agn in iwlcore.
At the same time, the fact that we removed the use of
the mac80211 LED triggers means we can also remove the
IWLWIFI_LEDS Kconfig symbol since the LED support is
now self-contained.
