    [PATCH] S2io: Multi buffer mode support · da6971d8
    Ananda Raju authored
    Hi,
    This patch  provides dynamic two buffer-mode and 3 buffer-mode options.
    Previously 2 buffer-mode was compilation option. Now with this patch applied
    one can load driver in 2 buffer-mode with module-load parameter
    
    ie.
    #insmod s2io.ko rx_ring_mode=2
    
    This patch also provides 3 buffer-mode which provides header separation
    functionality. In 3 buffer-mode skb->data will have L2/L3/L4 headers and
    "skb_shinfo(skb)->frag_list->data" will have have L4 payload.
    one can load driver in 3 buffer-mode with same above module-load parameter
    
    ie.
    #insmod s2io.ko rx_ring_mode=3
    
    Please review the patch.
