Re: cannot find manpage for 3c509 driver - how to specify "fullduplex " as mediaoption in hostname.if for this NIC ?

["A. Farber" <Alexander_(_dot_)_Farber_(_at_)_t-online_(_dot_)_de>]

"man ep" tells:

           media 10baseT mediaopt full-duplex
                Set 10baseT (UTP) operation and force full-duplex mode.

           media 10baseT mediaopt half-duplex
                Set 10baseT (UTP) operation and force half-duplex mode.

but is there a way to see if I have half- or full-duplex, 
I don't see anything "duplex" in the output below?

simplex:alex {47} ifconfig ep0
ep0: flags=8863<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        address: 00:a0:24:6b:a8:b4
        media: Ethernet 10baseT
        inet 192.168.1.36 netmask 0xffffff00 broadcast 192.168.1.255
        inet6 fe80::2a0:24ff:fe6b:a8b4%ep0 prefixlen 64 scopeid 0x2
simplex:alex {48} ifconfig -m ep0

ep0: flags=8863<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        address: 00:a0:24:6b:a8:b4
        media: Ethernet 10baseT
        supported media:
                media 10baseT
                media 10base5
                media 10base2
        inet 192.168.1.36 netmask 0xffffff00 broadcast 192.168.1.255
        inet6 fe80::2a0:24ff:fe6b:a8b4%ep0 prefixlen 64 scopeid 0x2

simplex:alex {49} cat /etc/hostname.ep0 
inet 192.168.1.36 255.255.255.0 NONE 

And can one have half-duplex and full-duplex NIC's
connected to the same switch? Thank you in advance
