    7373== 2) Addressable registers and buffers ==
    7474
    75 In a virtualized environment each channel segment will be mapped in the address space of a different virtual machine.
    76 Each channel takes a segment of 32 Kbytes in the address space, to simplify the address decoding, but only 20K bytes are used.
     75The addressable registers can be split in two classes: ''global'' registers, and ''channel'' registers.
    7776
    78  * The first 4 Kbytes contain the RX_0 container data
    79  * The next  4 Kbytes contain the RX_1 container data
    80  * The next  4 Kbytes contain the TX_0 container data
    81  * The next  4 Kbytes contain the TX_1 container data
    82  * The next  4 Kbytes contain the channel addressable registers:

     79These registers are used for global NIC configuration or status, and are not linked to a specific channel:
