I found something interesting with the latests bnx2 drivers, RX buffers can be way bigger.

Driver 1.6.9:

    Ring parameters for eth0:
    Pre-set maximums:

    RX:             1020
    RX Mini:        0
    RX Jumbo:       0
    TX:             255

Driver 1.7.4:

    Pre-set maximums:

    RX:             1020
    RX Mini:        0
    RX Jumbo:       4080
    TX:             255

Driver 1.8.1c

    Pre-set maximums:

    RX:             4080
    RX Mini:        0
    RX Jumbo:       16320
    TX:             255
