Hello,
I installed 5.4-RELEASE on one of my machines and have the problem
that my 3c905B-TX NIC seems to accept packets only when in promiscuous
mode. (I first noticed, that everything works when tcpdump is running
and then just used `ifconfig xl0 promisc' to get the NIC working)
Sending packets seems to work, because if I try to ping another
machine and run tcpdump on the ping-target, I see the ARP requests as
well as the ARP replies but the replies don't seem to get
accepted/recognized by the ping-source -- until I put the NIC on the
ping-source into promiscuous mode.
Once the 5.4-machine knows the ping-target's MAC address (after having
been in promiscuous mode), I see the echo requests and replies on the
ping-target but the replies also don't get accepted/recognized by the
ping source.
When I use another NIC (RealTek 8139 10/100BaseTX) on the 5.4-machine,
everything works fine. Also, the 3c905B-TX NIC worked fine under
4.11-STABLE.
As everything works fine when I use another NIC, I thought that there
might be a problem with the xl driver and I tried to use the earliest
if_xl.c and if_xlreg.h from the RELENG_5 branch but that didn't help.
Then, I tried to use the driver files that were used in the
4.11-STABLE version under which the NIC worked well, but that turned
out not to be such a trivial task.
I would be glad if someone could give me a hint on how I can solve
this problem?
Dirk
