Subject: [PATCH 2/2] net: ethernet: ni65: Fix cast from pointer to integer of different size

"buffer" array is unsigned long so casting of pointer to u32 causes
warning (compile testing on alpha architecture):

    drivers/net/ethernet/amd/ni65.c: In function ‘ni65_stop_start’:
    drivers/net/ethernet/amd/ni65.c:751:16: warning:
        cast from pointer to integer of different size [-Wpointer-to-int-cast]
