As far as other ethernet drivers, using vmalloc seems fairly common:
e1000/e1000_main.c: txdr->buffer_info = vmalloc(size);
e1000/e1000_main.c: rxdr->buffer_info = vmalloc(size);
bnx2.c: bp->rx_buf_ring = vmalloc(sizeof(struct sw_bd) * RX_DESC_CNT *
[bnx2x does the same thing but hides it in a macro]
ixgbe/ixgbe_main.c: txdr->tx_buffer_info = vmalloc(size);
ixgbe/ixgbe_main.c: rxdr->rx_buffer_info = vmalloc(size);
e1000e/netdev.c: tx_ring->buffer_info = vmalloc(size);
e1000e/netdev.c: rx_ring->buffer_info = vmalloc(size);
netxen/netxen_nic_main.c: cmd_buf_arr = (struct netxen_cmd_buffer
*)vmalloc(TX_RINGSIZE);
Sounds like we can do this as well.
Or.
