    v18 v19  
    6969 * '''is_isr''' : boolean (RX transfer if non zero)
    7070 * '''buffer''' is the user buffer virtual base address.
     71It supports concurrent kernel access to the chbuf, because It takes the lock protecting exclusive access to the chbuf pointer (index field).
    7172It is blocking if the kernel chbuf is empty (for an RX transfer) or full (for a TX transfer). The bloking situation
    7273is bounded by a timeout defined by the GIET_NIC_TIMEOUT parameter defined in the ''giet_config.h'' file.
