10: qe \- DEC DEQNA Q-bus 10 Mb/s Ethernet interface
11: .SH SYNOPSIS
12: .B "device qe0 at uba? csr 174440 vector qeintr"
13: .SH DESCRIPTION
14: The
15: .B qe
16: interface provides access to a 10 Mb/s Ethernet network through
17: the DEC DEQNA Q-bus controller.
18: .PP
19: Each of the host's network addresses
20: is specified at boot time with an SIOCSIFADDR
21: ioctl. The
22: .B qe
23: interface employs the address resolution protocol described in
24: arp(4P)
25: to map dynamically between Internet and Ethernet addresses on the local
26: network.
27: .PP
28: The interface normally tries to use a ``trailer'' encapsulation
29: to minimize copying data on input and output.
30: The use of trailers is negotiated with ARP.
31: This negotiation may be disabled, on a per-interface basis,
32: by setting the IFF_NOTRAILERS
33: flag with an SIOCSIFFLAGS ioctl.
34: .SH DIAGNOSTICS
35: .SH SEE ALSO
36: inet(4F), intro(4N), arp(4P)
