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
.
