shared by all the functions, driver does nothing when the space is
exhausted. This patch preallocates the space of unicast mac vlan
table for each function by software. Each function can only use its
private space and available shared space, avoiding single function
exhausts too much space, and other functions are unable to add

is the condition for matching, includes tuples of L2/L3/L4 header.
Action is the behaviour when a packet matches with the input key, such

The input key is stored in the tcam blocks, Each bit of input key can

port speed configuration, checks the link status and traffic status per
second, and updates the blink status of link led, traffic led and speed
led.

Now, the firmware takes responsibility to handle the led, the dirver just
needs to deal with locate command.

So the codes for link led, traffic led and speed led are useless now. This

When setting MTU, actually what we do is configuring the max frame size
for the hardware. ETH_HLEN、ETH_FCS_LEN and VLAN_HLEN must need to be
considered. And the frame size which is less than the default value
should not be set to the hardware. Because in the hardware, the the max
frame size not only controls the RX packet size, but also controls the
TX packet size. the RX packets whose size are greater than the setting
value will be dropped.

This patch fixes the bug setting a error max frame size to hardware.
