Subject: [PATCH 0/9] atl1: add napi to Atheros L1 NIC

Added NAPI interface to the driver of Atheros L1 NIC.
RX speed reported by iperf in TCP mode (with and without -N
switch) improved by ~7 Mbps. In UDP mode the speed up is
improved by ~4 Mbps.
Also hard RX/TX rings processing with memory allocation in
interrupt handlers is not very good idea. So, fixed this.

Note: thouse patches must be applied after patch, that fix
kernel panic in this driver.
Its subject is: "atl1: fix kernel panic in case of DMA errors"

Tony Zelenoff (9):
  atl1: handle rx in separate condition
  atl1: make driver napi compatible
  atl1: add napi process of tx interrupts
  atl1: use defined functions to disable irq
  atl1: make function to set imr of card
  atl1: add value to check ability of reenabling IRQs
  atl1: enable errors and link ints when rx/tx scheduled
  atl1: do not process interrupts in cycle in handler
  atl1: do not drop rx/tx interrupts before they are scheduled
