Random fixes mostly related to HT performance.
v1 -> v2:
- drop patch "rt2800: make ba_size depend on ampdu_factor"
- fix changelog for patch "rt2800: do not overwrite WPDMA_GLO_CFG_WP_DMA_BURST_SIZE"
Stanislaw Gruszka (9):
rt2800: correctly report MCS TX parameters
rt2800usb: do not wipe out USB_DMA_CFG settings
rt2800: OFDM rates are mandatory
rt2800: do not overwrite WPDMA_GLO_CFG_WP_DMA_BURST_SIZE
rt2800: correct AUTO_RSP_CFG
rt2800: correct TX_SW_CFG1 for 5592
rt2800: use RTS/CTS protection instead of CTS-to-self
rt2800: tune *_PROT_CFG parameters
rt2800: disable CCK rates on HT

We should only set IEEE80211_HT_MCS_TX_RX_DIF when TX and RX MCS sets
are not equal, i.e. when number of tx streams is different than
number of RX streams.

We should not reset USB_DMA_CFG on rt2800usb_init_registers() as this
function is called indirectly from rt2800_enable_radio(). If we
do so, we wipe out USB_DMA_CFG settings from rt2800usb_enable_radio().

We already initlized WPDMA_GLO_CFG_WP_DMA_BURST_SIZE to 3 on
rt2800_init_registers() for USB devices. For PCI devices we will use
HW default setting, which is 2, so patch does not change behaviour
on PCI devices.

Initialize AUTO_RSP_CFG register to similar value as vendor driver does.
Do not set BAC_ACK_POLICY based on short preamble setting, those are
unrelated.

Change default to RTS/CTS protection. This has a cost of transmitting
one more control frame (RTS) however protect us from traffic from
hidden node.
On station mode will use CTS-to-self if AP will configure that
for the network.

Use RTS/CTS protection for TXOP on all rates modes as default and
disable CCK rates (this cause performance problems).
