/*
|

|
|
* To save space in the binary when multiple-driver images are
|
||
|
|
* compiled, uninitialised data areas can be shared between drivers.
|
||
|
|
* This will typically be used to share statically-allocated receive
|
||
|
|
* and transmit buffers between drivers.
|
||
|
|
*
|
||
|
|
* Use as e.g.
|
||
|
|
*
|
||
|
|
* struct {
|
||
|
|
* char rx_buf[NUM_RX_BUF][RX_BUF_SIZE];
|
||
|
|
* char tx_buf[TX_BUF_SIZE];
|
||
|
|
* } my_static_data __shared;
