The
dge device driver supports the Intel i82597EX PRO/10GbE LR Ethernet adapter, which uses a single mode fiber (1310nm) interface.
The i82597EX supports IPv4/TCP/UDP checksumming in hardware, as well as TCP Segmentation Offloading (TSO). The driver does currently only support the hardware checksumming features. See
ifconfig(8) for information on how to enable the hardware checksum calculations.
The driver also makes use of the
ifconfig(8) link flags
link0 and
link1 to set the PCIX burst size. The burst size is set according to this table:
A larger burst size will increase the transmit capacity of the card dramatically but may have negative effect on other devices in the system.
