Re: Kernel 2.6.12-rc6-mm1 & Chelsio driver

Hi Lukas,

It looks like you have a T110 card (10Gb TOE) by the device ID 0006.
The Chelsio driver which is in the 2.6 mm tree only supports the NIC model cards (N110 & N210).

We currently don't have the TOE API in the Linux kernel so the TOE functionality does not exist, therefore you can only use the Chelsio modified 2.6.6 kernel for TOE.

You will need to download the driver from Chelsio's website for the T110. Please send me an email if you don't have a login.

Thanks,

As a quick hack, one could cross fingers and add a
CH_DEVICE(6, 0, CH_BRD_N110_1F)

or, if it does not work:

CH_DEVICE(6, 1, CH_BRD_N210_1F)


I added:

enum {
        CH_BRD_T110_1F,
        CH_BRD_N110_1F,
        CH_BRD_N210_1F,
        CH_BRD_T210_1F,
};

struct pci_device_id t1_pci_tbl[] = {
        CH_DEVICE(6, 0, CH_BRD_T110_1F),
        CH_DEVICE(6, 1, CH_BRD_T110_1F),
        CH_DEVICE(7, 0, CH_BRD_N110_1F),
        CH_DEVICE(10, 1, CH_BRD_N210_1F),
        { 0, }
};

according to 2.6.6 driver. However, it seems to be highly unstable. Using iperf it gets broken. Card receives packets but it does not transmit after some iperf tests.

Using tcpdump I see things like this:
tcpdump -ni eth0
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth0, link-type EN10MB (Ethernet), capture size 96 bytes

If it does not work at all, someone will have to dissect the whole
thing. Please fill an entry at bugzilla.kernel.org, add it your lspci info
and make it link the 2.6.6 driver from Chelsio's website.


Should I still add an bugzilla entry? Unfortunately, 2.6.6. driver from website
is accessible only through password.
