Hello,
I was trying to connect a FreeBSD box with an integrated realtek network card
to a hub but the re driver is unable to set the card in half-duplex:
# ifconfig re0 inet 10.20.30.40 netmask 255.255.255.0 mtu 1492 media 10baseT/UTP mediaopt half-duplex up
ifconfig: SIOCSIFMEDIA (mediaopt): Device not configured
#
# ifconfig re0 inet 10.20.30.40 netmask 255.255.255.0 mtu 1492 media 10baseT/UTP mediaopt full-duplex up
#
however, the man page for this driver states that both modes are supported:
[....]
The re driver supports the following media options:
full-duplex Force full duplex operation.
half-duplex Force half duplex operation.
[....]
because this I have a lot of collisions in the hub port.
I think either the re driver is unable to manage half-duplex on this chip or
simply the man page is wrong.
Regards.
