chxge - Chelsio Ethernet network interface controllers
Ethernet driver is a multi-threaded, loadable, clonable,
STREAMS hardware driver supporting the connectionless Data Link Provider
, over Chelsio NIC controllers. Multiple (and mixed)
NIC controllers installed within the system are supported by the
driver. The chxge
driver provides basic support for the NIC hardware.
Functions include chip initialization, frame transmit and receive, and
error recovery and reporting.
APPLICATION PROGRAMMING INTERFACE
The cloning, character-special device /dev/chxge
is used to access NIC
devices installed within the system.
CHXGE AND DLPI
driver is dependent on /kernel/misc/gld
, a loadable kernel
module that provides the chxge
driver with the DLPI and STREAMS
functionality required of a LAN driver. See gld(4D)
for more details on
the primitives supported by the driver.
The values returned by the driver in the DL_INFO_ACK primitive in
response to the DL_INFO_REQ are:
o Default Maximum SDU is 1500 (ETHERMTU).
o dlsap address length is 8.
o MAC type is DL_ETHER.
o The sap length value is -2, meaning the physical address
component is followed immediately by a 2-byte sap component
within the DLSAP address.
o Broadcast address value is Ethernet/IEEE broadcast address
