mode master ?
not really tested:

$ man iwconfig

mode   Set the operating mode of the device, which depends on the  net-
              work  topology. The mode can be Ad-Hoc (network composed 
of only
              one cell and without Access Point), Managed (node connects 
to  a
              network  composed  of  many Access Points, with roaming), 
Master
              (the node is the synchronisation master or  acts  as  an  
Access
              Point),  Repeater (the node forwards packets between other 
wire-
              less  nodes),  Secondary  (the  node  acts  as  a  
backup   mas-
              ter/repeater),  Monitor  (the node acts as a passive 
monitor and
              only receives packets) or Auto.
              Example :
                   iwconfig eth0 mode Managed
                   iwconfig eth0 mode Ad-Hoc

# iwconfig eth2 mode master
