Mattias Nissler 2676c94d4e rt2x00: Rework rt73 antenna selection
This patch changes rt73 antenna selection to what I believe is the correct way.
It also fixes a small selection bug that switched the antennas by accident.

Mattias Nissler acaa410d06 rt2x00: Rework rt61 antenna selection.
This patch changes rt61 antenna selection again. It helps at least with the
rt61 pci card in my box, I hope I haven't broken behaviour on other RF chips.
RF 2529 antenna setup is incomplete, we need to at code for diversity when we
figure out how it is done properly.

Ivo van Doorn e4cd2ff89f rt2x00: Split rt61/rt73 antenna selection into RX and TX antenna
Based on investigation of the legacy drivers, I have made the
following assumptions of the antenna setup:
 - R77 is the TX antenna configuration
 - RF2529 fetches default antenna selection from NIC eeprom word

With these assumptions we can change the antenna configuration
to correctly read both antenna setup values and correctly
configure the antenna. And we can now also configure the antenna
for RF2529 without a double antenna.

Ivo van Doorn 69f81a2cac [PATCH] rt2x00: Implement SW diversity
When mac80211 indicates that the default antenna setup
should be used _and_ that this default setup is SW_DIVERSITY.

This requires sampling and storing the RSSI per antenna
and check once every 2 seconds to determine if the RSSI
has changed significantly. Once this is the case we should sample
the other antenna for a short period and evaluate if
we need to swap antenna or not.

Although ANTENNA_SW_DIVERSITY should never be send

But instead of defaulting to ANTENNA_HW_DIVERSITY we
should default to ANTENNA_B instead.

Ivo van Doorn addc81bd42 [PATCH] rt2x00: Correctly translate mac80211 antenna setup to rt2x00
mac80211 has 3 values for the antenna setup:
 0 - default
 1 - use antenna 1
 2 - use antenna 2

This means that rt2x00 should store the default value
from the EEPROM somwhere and use that when mac80211 indicates
that the antenna setup is 0.
This also implies that rt2x00 should no longer write the
hw->config.antenna_sel_* values based on the EEPROM input.

This also adds the basis in rt2x00lib for correct software
diversity handling. By default rt2x00lib will now configure
antenna B instead of hardware diversity.

Matt Carlson ef167e2703 [TG3]: Fix supporting flowctrl code
This patch does three things.  It modifies tg3_setup_flow_control() to
use the administrator requested flow control settings if
autonegotiation is turned off.  It slightly modifies the
tg3_setup_fiber_mii_phy() function to account for this new use case.
And finally, it does the same for tg3_setup_copper_phy().

The copper modifications are more than a small multi-line change.  The
new code makes an attempt to avoid a link renegotiation if the link is
active at half duplex and the only difference between the current
advertised settings and requested advertised settings is the
flow control advertisements.

If the driver reports a specific scan capability, the driver must

so, in which case it must return an error.

This version switches to Dave Kilroy's suggestion of claiming unused
