| u32 ath5k_hw_get_rx_filter | ( | struct ath5k_hw * | ah | ) |
ath5k_hw_get_rx_filter - Get current rx filter
: The &struct ath5k_hw
Returns the RX filter by reading rx filter and phy error filter registers. RX filter is used to set the allowed frame types that PCU will accept and pass to the driver. For a list of frame types check out reg.h.

ath5k_hw_set_ack_bitrate - set bitrate for ACKs
: The &struct ath5k_hw : Flag to determine if we want to use high transmition rate for ACKs or not
If high flag is set, we tell hw to use a set of control rates based on the current transmition rate (check out control_rates array inside reset.c). If not hw just uses the lowest rate available for the current modulation scheme being used (1Mbit for CCK and 6Mbits for OFDM).

| int ath5k_hw_set_bssid_mask | ( | struct ath5k_hw * | ah, |

| ) |
ath5k_hw_set_bssid_mask - filter out bssids we listen
: the &struct ath5k_hw : the bssid_mask, a u8 array of size ETH_ALEN
BSSID masking is a method used by AR5212 and newer hardware to inform PCU which bits of the interface's MAC address should be looked at when trying to decide which packets to ACK. In station mode and AP mode with a single BSS every bit matters since we lock to only one BSS. In AP mode with multiple BSSes (virtual interfaces) not every bit matters because hw must accept frames for all BSSes and so we tweak some bits of our mac address in order to have multiple BSSes.
NOTE: This is a simple filter and does *not* filter out all relevant frames. Some frames that are not for us might get ACKed from us by PCU because they just match the mask.
When handling multiple BSSes you can get the BSSID mask by computing the set of ~ ( MAC XOR BSSID ) for all bssids we handle.
When you do this you are essentially computing the common bits of all your BSSes. Later it is assumed the harware will "and" (&) the BSSID mask with the MAC address to obtain the relevant bits and compare the result with (frame's BSSID & mask) to see if they match.
