hw

The hardware the algorithm is invoked for.

sband

The band this frame is being transmitted on.

bss_conf

the current BSS configuration

skb

the skb that will be transmitted, the control information in it needs to be filled in

reported_rate

The rate control algorithm can fill this in to indicate which rate should be reported to userspace as the current rate and used for rate calculations in the mesh network.

rts

whether RTS will be used for this frame because it is longer than the RTS threshold

short_preamble

whether mac80211 will request short-preamble transmission if the selected rate supports it

max_rate_idx

user-requested maximum (legacy) rate (deprecated; this will be removed once drivers get updated to use rate_idx_mask)

rate_idx_mask

user-requested (legacy) rate mask

rate_idx_mcs_mask

user-requested MCS rate mask (NULL if not in use)

bss

whether this frame is sent out in AP or IBSS mode
