sk_filter(9) [centos man page]

SK_FILTER(9)							 Linux Networking						      SK_FILTER(9)

NAME

       sk_filter - run a packet through a socket filter

SYNOPSIS

       int sk_filter(struct sock * sk, struct sk_buff * skb);

ARGUMENTS

       sk
	   sock associated with sk_buff

       skb
	   buffer to filter

DESCRIPTION

       Run the filter code and then cut skb->data to correct size returned by sk_run_filter. If pkt_len is 0 we toss packet. If skb->len is
       smaller than pkt_len we keep whole skb->data. This is the socket level wrapper to sk_run_filter. It returns 0 if the packet should be
       accepted or -EPERM if the packet should be tossed.

SYNOPSIS

       struct ieee80211_tx_rate_control {
	 struct ieee80211_hw * hw;
	 struct ieee80211_supported_band * sband;
	 struct ieee80211_bss_conf * bss_conf;

MEMBERS

       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
