See 40.Xr mii 4 . 41.Sh DESCRIPTION 42The 43.Nm 44driver provides support for the Xircom CreditCard family of PCMCIA 45Ethernet adapters. Supported cards include: 46.Pp 47.Bl -item -compact -offset indent 48.It 49Xircom CreditCard Ethernet II 50.It 51Xircom CreditCard 10/100 Ethernet 52.\" .It Xircom CreditCard Ethernet + Modem 53.\" .It Xircom CreditCard 10/100 Ethernet + Modem 54.It 55Xircom RealPort 10/100 Ethernet + Modem (Ethernet function only) 56.It 57Intel EtherExpress Pro/100 58.It 59Compaq Netelligent 10/100 60.El 61.Pp 62Cards which should work, but have not been confirmed include: 63.Pp 64.Bl -item -compact -offset indent 65.It 66Xircom RealPort Ethernet 67.It 68Xircom RealPort 10/100 Ethernet 69.El 70.Pp 71Some Xircom Ethernet products are supported by the 72.Xr tlp 4 73driver. 74.Sh MEDIA SELECTION 75Media selection is done using 76.Xr ifconfig 8 77using the standard 78.Xr ifmedia 4 79mechanism. Refer to those manual pages for more information. 80.Sh SEE ALSO 81.Xr ifmedia 4 , 82.Xr mii 4 , 83.Xr netintro 4 , 84.Xr pcmcia 4 , 85.Xr tlp 4 , 86.Xr xirc 4 , 87.Xr ifconfig 8 88.Sh HISTORY 89The 90.Nm 91device driver appeared in 92.Nx 1.5 . 93.Sh BUGS 94The driver suffers from poor performance. Even with the 10/100 cards, 95do not expect more than ~450KB/s. Some 10/100 cards may not autonegotiate 96reliably and require manual media selection. 97.Pp 98The Xircom multifunction cards which contain both Ethernet and modem 99interfaces are known to have problems. This is due to the card not 100reporting itself correctly as a multifunction card. 101
