NAME

       cfg80211_testmode_alloc_reply_skb - allocate testmode reply

SYNOPSIS

       struct sk_buff * cfg80211_testmode_alloc_reply_skb(struct wiphy * wiphy, int approxlen);

ARGUMENTS

       wiphy
	   the wiphy

       approxlen
	   an upper bound of the length of the data that will be put into the skb

DESCRIPTION

       This function allocates and pre-fills an skb for a reply to the testmode command. Since it is intended for a reply, calling it outside of
       the testmode_cmd operation is invalid.

       The returned skb is pre-filled with the wiphy index and set up in a way that any data that is put into the skb (with skb_put, nla_put or
       similar) will end up being within the NL80211_ATTR_TESTDATA attribute, so all that needs to be done with the skb is adding data for the
       corresponding userspace tool which can then read that data out of the testdata attribute. You must not modify the skb in any other way.

       When done, call cfg80211_testmode_reply with the skb and return its error code as the result of the testmode_cmd operation.

RETURN

       An allocated and pre-filled skb.  NULL if any errors happen.

NAME

       regulatory_hint - driver hint to the wireless core a regulatory domain

SYNOPSIS

       int regulatory_hint(struct wiphy * wiphy, const char * alpha2);

ARGUMENTS

       wiphy
	   the wireless device giving the hint (used only for reporting conflicts)

       alpha2
	   the ISO/IEC 3166 alpha2 the driver claims its regulatory domain should be in. If rd is set this should be NULL. Note that if you set
	   this to NULL you should still set rd->alpha2 to some accepted alpha2.

DESCRIPTION

       Wireless drivers can use this function to hint to the wireless core what it believes should be the current regulatory domain by giving it
       an ISO/IEC 3166 alpha2 country code it knows its regulatory domain should be in or by providing a completely build regulatory domain. If
       the driver provides an ISO/IEC 3166 alpha2 userspace will be queried for a regulatory domain structure for the respective country.

       The wiphy must have been registered to cfg80211 prior to this call. For cfg80211 drivers this means you must first use wiphy_register, for
       mac80211 drivers you must first use ieee80211_register_hw.

       Drivers should check the return value, its possible you can get an -ENOMEM.

RETURN

       0 on success. -ENOMEM.
