Interrupt Handler of Ethernet Device

[Rami Rosen]

Hi,
we have in :
 http://lxr.free-electrons.com/source/drivers/net/ethernet/intel/e100.c

struct nic {
        /* Begin: frequently used values: keep adjacent for cache effect */
        u32 msg_enable                          ____cacheline_aligned;
        struct net_device *netdev;
         struct pci_dev *pdev;
     ...
     ...

And indeed  nic->netdev represents an Ethernet interface, which
is the struct net_device (see: include/linux/netdevice.h)

Regards,
Rami Rosen
