Serial / Ethernet switch about elks HOT 9 OPEN

I implemented the switch and can see that ktcp successfully opens and initializes the ne2k driver. Also I checked that ktcp queries the ne2k driver with select.

How to proceed? Shall I send you my changes as commits?

Well... good question. As you took the leadership on the KTCP part, I think the best would be to commit your changes related to KTCP + Ethernet in a dedicated branch in your repository, so that one can follow your progress, and can pull from that branch to get your code and test it. I would be the first puller, for sure !

Ok, I will make a ne2k branch in my repository and commit the changes to that.

Including your driver/net directory and qemu script.

I just pushed my changes to the ktcp code directory plus the rc.sysinit file to a new ne2k branch in my repo. https://github.com/georgp24/elks/commits/ne2k

Please check why this code does not receive any data. For test it will print out the length of received packets. This will show if anything is received at all. See the deveth.c file.

I made the branch after committing the modified kill command and the ported miniterm program. These are not needed for networking.

from elks.

I pulled your branch ne2k as is, and did the test as described in #18.
I can see that ktcp receives the ARP packets:

login: root
# deveth_process() called!
64 bytes read

from elks.

Looks good! Then I have to try to get the same result.

How can ktcp read the mac address of the ne2k card? It needs this for the ARP-Reply.

from elks.

For the moment, take the same MAC as in the driver:

static byte_t mac_addr [6] = {0x52, 0x54, 0x00, 0x12, 0x34, 0x56};  // QEMU default

I will implement the needed ioctl() later. This is tracked by #24.

from elks.

I got it to work as well. However, it takes 45 seconds until the packets arrive at ktcp. I did not expect that and did not wait that long before.

from elks.

Issue #24 has been closed, so from now you can use ioctl() on /dev/eth to get the MAC address.
