SKB_FIND_TEXT(9) Linux Networking SKB_FIND_TEXT(9)NAME
skb_find_text - Find a text pattern in skb data
SYNOPSIS
unsigned int skb_find_text(struct sk_buff * skb, unsigned int from, unsigned int to, struct ts_config * config, struct ts_state * state);
ARGUMENTS
skb
the buffer to look in
from
search offset
to
search limit
config
textsearch configuration
state
uninitialized textsearch state variable
DESCRIPTION
Finds a pattern in the skb data according to the specified textsearch configuration. Use textsearch_next to retrieve subsequent occurrences
of the pattern. Returns the offset to the first occurrence or UINT_MAX if no match was found.

STRUCT IEEE80211_TX_(9) Rate control interface STRUCT IEEE80211_TX_(9)NAME
struct_ieee80211_tx_rate_control - rate control information for/from RC algo
SYNOPSIS
struct ieee80211_tx_rate_control {
struct ieee80211_hw * hw;
struct ieee80211_supported_band * sband;
struct ieee80211_bss_conf * bss_conf;

bool rts;
bool short_preamble;

u8 * rate_idx_mcs_mask;
bool bss;
};
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
