The mechanism used to initiate work events from the interrupt
handler has a classic read/modify/write race between the interrupt
handler that sets the condition, and the worker task that reads and
clears the condition. Close these races by using atomic
bit fields.

struct net_device has its own struct net_device_stats member, so use
this one instead of a private copy in the atl1c_adapter struct.

Add AR8151 v2.0 Gigabit 1000 support
Change jumbo frame size to 6K
Update L0s/L1 rountine
when link speed is 100M or 1G, set L1 link timer to 4 for l1d_2 and l2c_b2
set L1 link timer to 7 for l2c_b, set L1 link timer to 0xF for others.
Update atl1c_suspend routine
just refactory the function, add atl1c_phy_power_saving routine,
when Wake On Lan enable, this func will be called to save power,
it will reautoneg PHY to 10/100M speed depend on the link
partners link capability.
Update atl1c_configure_des_ring
do not use l2c_b default SRAM configuration.

AR8151 is a Gigabit Ethernet device. AR8152 devices are
Fast Ethernet devices, there are two revisions, a 1.0
and a 2.0 revision.
This has been tested against these devices:
Driver Model-name vendor:device Type
atl1c AR8131 1969:1063 Gigabit Ethernet
atl1c AR8132 1969:1062 Fast Ethernet
atl1c AR8151(v1.0) 1969:1073 Gigabit Ethernet
atl1c AR8152(v1.1) 1969:2060 Fast Ethernet
This device has no hardware available yet so it goes untested,
but it should work:
atl1c AR8152(v2.0) 1969:2062 Fast Ethernet

use common_task instead of reset_task and link_chg_task, so it fix "call cancel_work_sync
from the work itself".

change atl1c_buffer struct, use "u16 flags" instead of "u16 state"
to store more infomation for atl1c_buffer, and restructure clean
atl1c_buffer procedure, add common api atl1c_clean_buffer.
