NAME
qe - DEC DEQNA Q-bus 10 Mb/s Ethernet interface
SYNOPSIS
/sys/conf/SYSTEM:
NQE _q_e__c_o_n_t_r_o_l_l_e_r_s # DEQNA
DESCRIPTION
The qe interface provides access to a 10 Mb/s Ethernet net-
work through the DEC DEQNA Q-bus controller.
Each of the host's network addresses is specified at boot
time with an SIOCSIFADDR ioctl. The qe interface employs
the address resolution protocol described in arp(4P) to map
dynamically between Internet and Ethernet addresses on the
local network.
The interface normally tries to use a ``trailer'' encapsula-
tion to minimize copying data on input and output. The use
of trailers is negotiated with ARP. This negotiation may be
disabled, on a per-interface basis, by setting the
IFF_NOTRAILERS flag with an SIOCSIFFLAGS ioctl.
