TX interrupt mitigation reduces the number of interrupts
by addressing several interrupt actions (AR_IMR_TXOK,
AR_IMR_TXDESC) all in one interrupt so when enabling
it discard setting the other interrupts.
Without this TX interrupt mitigation would actually
increase the number of interrupts two-fold. We still
leave TX interrupt mitigation disabled as it is still
being tested.

There is a small race between when the tx queues are stopped
and when netif_carrier_off() is called in ixgbe_down. If the
dev_watchdog() timer fires during this time it is possible for
a false tx timeout to occur.
This patch moves the netif_carrier_off() so that it is called before
the tx queues are stopped preventing the dev_watchdog timer from
detecting false tx timeouts. The race is seen occosionally when
FCoE or DCB settings are being configured or changed.
Testing note, running ifconfig up/down will not reproduce this
issue because dev_open/dev_close call dev_deactivate() and then
dev_activate().

82598/82599 can support EITR == 0, which allows for the
absolutely lowest latency setting in the hardware. This disables
writeback batching and anything else that relies upon a delayed
interrupt. This patch enables the feature of "override" when a
user sets rx-usecs to zero, the driver will respect that setting
over using RSC, and automatically disable RSC. If rx-usecs is
used to set the EITR value to 0, then the driver should disable
LRO (aka RSC) internally until EITR is set to non-zero again.

Calls to twsk_net() are in some cases protected by reference counting
as an alternative to RCU protection. Cases covered by reference counts
include __inet_twsk_kill(), inet_twsk_free(), inet_twdr_do_twkill_work(),
inet_twdr_twcal_tick(), and tcp_timewait_state_process(). RCU is used
by inet_twsk_purge(). Locking is used by established_get_first()
and established_get_next(). Finally, __inet_twsk_hashdance() is an
initialization case.
It appears to be non-trivial to locate the appropriate locks and
reference counts from within twsk_net(), so used rcu_dereference_raw().

Prompted by a previous patch submitted by Matthew Garret <mjg@redhat.com>,
further digging into errata documentation reveals the current enabling or
disabling of ASPM L0s and L1 states for certain parts supported by this
driver are incorrect. 82571 and 82572 should always disable L1. For
standard frames, 82573/82574/82583 can enable L1 but L0s must be disabled,
and for jumbo frames 82573/82574 must disable L1. This allows for some
parts to enable L1 in certain configurations leading to better power
savings.
Also according to the same errata, Early Receive (ERT) should be disabled
on 82573 when using jumbo frames.
