The ieee80211_encap
() function
encapsulates an outbound data frame contained within the mbuf chain
m from the interface ic. The
argument ni is a reference to the destination
node.
If the function is successful, the mbuf chain is updated with the
802.11 frame header prepended, and a pointer to the head of the chain is
returned. If an error occurs, NULL
is returned.
The ieee80211_add_rates
() utility function
is used to add the rate set element *rs to the frame
frm. A pointer to the location in the buffer after the
addition of the rate set is returned. It is typically used when constructing
management frames from within the software 802.11 stack.
The ieee80211_add_xrates
() utility
function is used to add the extended rate set element
*rs to the frame frm. A pointer
to the location in the buffer after the addition of the rate set is
returned. It is typically used when constructing management frames from
within the software 802.11 stack in 802.11g mode.
The ieee80211_send_mgmt
() function
transmits a management frame on the interface ic to
the destination node ni of type
type.
The argument arg specifies either a sequence number for authentication operations, a status code for [re]association operations, or a reason for deauthentication and deassociation operations.
Nodes other than ic_bss have their reference count incremented to reflect their use for an indeterminate amount of time. This reference is freed when the function returns.
The function returns 0 if successful; if temporary buffer space is
not available, the function returns ENOMEM
.
ieee80211
series of functions first appeared in
NetBSD 1.5, and were later ported to
FreeBSD 4.6.
