|
|
|
|
The
|
|
|
|
|
.Nm
|
2007-10-19 08:57:48 +04:00
|
|
|
driver supports Ethernet interfaces based on the Micrel 8842/8841
|
|
|
|
|
PCI Ethernet chips. The 8842 has 2 Ethernet ports which behave as
|
|
|
|
|
a managed switch to bridge each other. It works like a T-shape
|
|
|
|
|
connector of Ethernet data flow in which an Ethernet controller
|
|
|
|
|
sits at the leg of the T. Frames can flow between the two ports
|
|
|
|
|
while traffic destined for the 8842 reaches the EMAC. The 8841 is
|
|
|
|
|
a plain 10/100 Ethernet.
|
|
|
|
|
The
|
|
|
|
|
.Nm
|
|
|
|
|
driver distinguishs and handles them according to the HW model.

.Sh BUGS
|
2007-10-19 09:11:07 +04:00
|
|
|
__STRICT_ALIGNMENT case is not written. 8842 media selection
|
2007-10-19 08:57:48 +04:00
|
|
|
keeps "auto" and indicates "up 100baseTX-FX flow" when either of
|
|
|
|
|
two ports is found link-up. There is no functional provision to
|
|
|
|
|
see and control the media selection of them this moment. Advanced
|
|
|
|
|
features like flow volume bound, VLAN tag insertion/removal, QoS
|
|
|
|
|
DiffServ are not implemented and remain uncontrollable by the
|
2006-07-01 01:25:59 +04:00
|
|
|
.Nm
|
|
|
|
|
driver.

|
|
|
UDP4CSUM is not very useful since the HW has an implementation
|
|
|
|
|
error for the case when a large UDP datagram is fragmented into
|
|
|
|
|
MTU sized frames.
