Problem with Ethernet controller 82579LM driver on X86 target
We have two Ethernet ports on our X86 target – 82574L and 82579LM. But the o/p of the ifconfig command shows only one
Ethernet port wm0 (82574L). We tried following commands as suggested in one of the posts in the forum, to kill and
restart the io-pkt process.
slay io-pkt-v4-hc
io-pkt-v4-hc -de1000
Still we could see only one Ethernet port wm0 as earlier.
Then we have used the network driver devnp-e1000 from the ‘Generic x86 BIOS_APIC BSP’. We have used the same commands
as mentioned above. Now the ifconfig shows both the Ethernet ports wm0 and wm1. But the problem is we are not able to
use both the ports simultaneously.
We did the following:
1] Connected two host PCs to target (PC1 on wm0 and PC2 on wm1)
2] Boot target and configure the IP address of both the Ethernet ports
3] At first, communication between PC1 and wm0 was tested by pinging each other
4] Communication was successful
5] Then, communication between PC2 and wm1 was tested by pinging each other
6] No response from the both the ends
7] Target was restarted and IP addresses of both the ports were configured
9] This time, communication between PC2 and wm1 was tested first by pinging each other
10] Communication was successful
11] Then, communication between PC1 and wm0 was tested by pinging each other
12] No response from the both the ends
How to make both the ports work at the same time?
