Hello :)
Last week I've been testing:
- speed selection and autonegotiation on RTL8169
- other variant of chip: RTL8168
I've also added switch to 'nic' utility which allows to get autonegotiation
back after selecting speed/duplex mode manually and merged recent mainline
changes onto my branch.
Here's example output from my version of 'nic' utility:
/ # nic
[Index]: [Service Name]
0: devices/\hw\pci0\01:06.0\port0
MAC address: 48:02:2a:07:58:4c
Vendor name: Realtek
Model name: RTL8169
Link state: down
1: devices/\hw\pci0\02:00.0\port0
MAC address: 90:2b:34:5d:c8:96
Vendor name: Realtek
Model name: RTL8168
Link state: up
Speed: 100Mbps full-duplex
You can eg. select 10Mbps half-duplex using 'nic 1 speed 10' and 'nic 1
duplex half' and then go back to autonegotiated speed using 'nic 1 auto'.
On RTL8169, link drops for a second when changing speed or duplex mode.
There's also option to set MAC address, but it isn't working on any NIC. I
found that's probably caused by IPC deadlock or something like that (when
calling nic_set_addr, implementing functions calls nic_report_address which
probably causes system to hang).
Now I really need to do some more heavy testing, especially using TCP and
large transfers which is still tough due to my issues when using TCP client
apps (nterm) on HelenOS.
