ath5k_hw_write_ofdm_timings - set OFDM timings on AR5212

: the &struct ath5k_hw : the currently set channel upon reset

Write the delta slope coefficient (used on pilot tracking ?) for OFDM operation on the AR5212 upon reset. This is a helper for ath5k_hw_reset().

Since delta slope is floating point we split it on its exponent and mantissa and provide these values on hw.

		unsigned int	mode
	)		[inline, static]

ath5k_hw_write_rate_duration - fill rate code to duration table

: the &struct ath5k_hw : one of enum ath5k_driver_mode

Write the rate code to duration table upon hw reset. This is a helper for ath5k_hw_reset(). It seems all this is doing is setting an ACK timeout on the hardware, based on current mode, for each rate. The rates which are capable of short preamble (802.11b rates 2Mbps, 5.5Mbps, and 11Mbps) have different rate code so we write their value twice (one for long preample and one for short).

Note: Band doesn't matter here, if we set the values for OFDM it works on both a and g modes. So all we have to do is set values for all g rates that include all OFDM and CCK rates. If we operate in turbo or xr/half/ quarter rate mode, we need to use another set of bitrates (that's why we need the mode parameter) but we don't handle these proprietary modes yet.
