XTE_MAX_JUMBO_FRAME_SIZE is over 9000 bytes and the default value for 'rx_bd_num' is RX_BD_NUM_DEFAULT (i.e. 1024) So this loop allocates more than 9 Mo of memory. Previous memory allocations in this function already use GFP_KERNEL, so use __netdev_alloc_skb_ip_align() and an explicit GFP_KERNEL instead of a implicit GFP_ATOMIC. This gives more opportunities of successful allocation.
