Tigon 3 driver & Netgear GA302T

Tigon 3 driver & Netgear GA302T

[James Morris]

Does the tg3 driver support the Netgear GA302T card (which I think uses 
the Altima AC1000 chip) ?

If it's the Altima then I guess so, otherwise I'd expect the 83820
driver to run it.

It appears to be the Altima, from the Freebsd cvs log comments & 
associated changes for their bge driver.

I'll be getting a couple of the cards on Friday and should find out pretty 
quickly after that.

Confirmed:

eth2: Tigon3 [partno(BAC91000A1) rev 7104 PHY(5411)] (PCI:33MHz:32-bit) 10/100/1000BaseT Ethernet 00:40:f4:35:f1:77
eth2: Link is up at 100 Mbps, full duplex.
eth2: Flow control is off for TX and off for RX.

Unfortunately, it's not successfully transmitting or receiving any 
packets.

Neighbor cache

[Xiaoning He]

Hi All

I have a question related to the Neighbor cache. I am currently trying
to modify the neighbor cache but I can not find where the code in the
IPv6 kernel. 

Could you please let me know in the IPv6 kernel, where the Neighbor
cache is maintained and which file contains them?

Thank you very much.

Neighbor cache behavior

[Xiaoning He]

Hi all

Thank you for answering my previous question about the neighbor cache. I
have a couple of more questions regarding the neighbor cache. Would you
please give me some help? 

My understanding about the behavior of neighbor cache is that when a AR
receives a packet for a destination, it will 

Check NC
If match, send the packet
If not
	Multicast NS
	Wait for NA
	Send the packet

Is this the correct behavior?

If so, I have looked into the Linux kernel, however, I don't know where
in the Linux kernel the code will check the Neighbor. I tried to search
the function ndisc_send_ns() because I think that's the function who
will handle the sending the NS is there is no entry in the NC. However,
it doesn't help. 

Could anyone provide me with some hints?

Also, I think I really need to know the Linux Kernel so that I don't
need always ask this kind of question. Is there any good book and
tutorial available which can give me a overall picture about how to
program the networking program for both user-land and kernel in the
Linux?

Thank you so much for your help.

skb->dst->output() is the entry to resolve neighbor when sending
packets.

keep reading source codes.:-)

Look for "struct neighbour" and "struct neigh_table" in neighbour.h and
it's usage. Functions are  neigh_lookup(), neigh_create(), neigh_destroy(),
etc.
