(1) Add an IOCTL to tell the Lucent based cards how often to
do an access point scan. These results are returned by
calling another IOCTL to get the most recent scan data.
This function works with prism2 cards as well, but the
data is returned in a different format, or perhaps it is
data only for the closest access point.
(2) For prism2 cards, add the ability to put it into LAN monitor
mode, where (via BPF) all packets can be received. This
mode works best with "wiconfig wi0 -p 3 -f ?" to put the
card into pseudo-IBSS mode (to keep it from channel-hopping
and scanning for access points) and to set the frequency of
the AP you wish to monitor.
The returned data has a partial wi_frame header (down to the
wi_dat_len field) followed by the raw data of the packet.
I have and will put up on http://www.flame.org/NetBSD/wireless/
some simple utilities which do some perhaps interesting things,
like scan for access points, capture packets, etc.
(eca_init_rx_soft()) just sets up software state, and the other of
which (eca_init_rx_hard()) actually puts the interface into receive
mode and sets up the FIQ handler etc. Arrange that when we transmit a
frame, eca_init_rx_soft() has already been called, so we only need to
call eca_init_rx_hard() from the Tx downgrade handler.
The point of this is that I should be able to incorporate the
functionality of eca_init_rx_hard() into the Tx FIQ handler so that we
can switch from Tx to Rx with little enough delay that we don't drop
the first few bytes of the incoming frame.
are only wired if this flag is present (i.e. they are not wired by default now)
loaned pages are unloaned via new uvm_unloan(), uvm_unloananon() and
uvm_unloanpage() are no longer exported
adjust uvm_unloanpage() to unwire the pages if UVM_LOAN_WIRED is specified
mark uvm_loanuobj() and uvm_loanzero() static also in function implementation
kern/sys_pipe.c: uvm_unloanpage() --> uvm_unloan()
