This patch addresses an issue where we did not restart auto-negotiation on
serdes links when the link partner was disabled and re-enabled. It includes
reworking the serdes link detect mechanism to be a state machine for
82571 and 82572 parts only.

RXSEQ interrupts were used to force link state interrogation of serdes
links, as the Si was not guaranteed to report LSC interrupts when the
link changed state. On some bladeservers this resulted in false link up
reports if no link partner was connected. The RXSEQ treatment is
not necessary, as the link can be monitored from the watchdog timer, and
the false link indications cease.

82571 and 82572 Errata #13 documents that the Si feature DMA Dynamic
Clock Gating should be disabled, and identifies the workaround of
disabling the feature by EEPROM setting. EEPROM versions that do not
include the recommended workaround have been found in the field, and so
some customers remain at risk. Because the feature DMA Dynamic clock
Gating can be disabled by directly setting the appropriate bit in the
E1000_CTRL_EXT register, this patch overrides the EEPROM setting, and
force-disables the feature.

Monitor mode is able to TX by using injected frames. We should
not allow injected frames to be sent unless allowed by regulatory
rules. Since AP mode uses a monitor interfaces to transmit
management frames we have to take care to not break AP mode as
well while resolving this. We can deal with this by allowing compliant
APs solutions to inform mac80211 if their monitor interface is
intended to be used for an AP by setting a cfg80211 flag for the
monitor interface. hostapd, for example, currently does its own
checks to ensure AP mode is not used on channels which require radar
detection. Once such solutions are available it can can add this
flag for monitor interfaces.

Giving the signal in dB isn't much more useful to userspace
than giving the signal in unspecified units. This removes
some radiotap information for zd1211 (the only driver using
this flag), but it helps a lot for getting cfg80211-based
scanning which won't support dB, and zd1211 being dB is a
little fishy anyway.
