NAME

6       freq_reg_info - get regulatory information for the given frequency
7

SYNOPSIS

9       const struct ieee80211_reg_rule * freq_reg_info(struct wiphy * wiphy,
10                                                       u32 center_freq);
11

ARGUMENTS

13       wiphy
14           the wiphy for which we want to process this rule for
15
16       center_freq
17           Frequency in KHz for which we want regulatory information for
18

DESCRIPTION

20       Use this function to get the regulatory rule for a specific frequency
21       on a given wireless device. If the device has a specific regulatory
22       domain it wants to follow we respect that unless a country IE has been
23       received and processed already.
24

RETURN

26       A valid pointer, or, when an error occurs, for example if no rule can
27       be found, the return value is encoded using ERR_PTR. Use IS_ERR to
28       check and PTR_ERR to obtain the numeric return value. The numeric
29       return value will be -ERANGE if we determine the given center_freq does
30       not even have a regulatory rule for a frequency range in the
31       center_freq's band. See freq_in_rule_band for our current definition of
32       a band -- this is purely subjective and right now it's 802.11 specific.
