devs-em.so

Syntax:

io-sock -d em [option[,option ...]]

mount -T io-sock [-o option[,option ...]] em

Runs on:

QNX Neutrino

Options:

Use commas, not spaces, to separate the options.

prefix=prefix: Specifies the instance of io-sock that mounts this driver. You specify the prefix that creates an alternative stack when you start io-sock. Used only when you load a driver with mount after starting io-sock.
qnxdev=device: When Plug & Play is disabled, specifies the device instance to use. Use devinfo -v to determine the location value to use (e.g., qnxdev=pci0:0:25:0).

Description:

The devs-em.so driver is ported from FreeBSD to provide support for Intel PRO/1000 Gigabit Ethernet adapters. Its interface names are in the form em# or igb#, where # is an integer of one or more digits.

For information on starting io-sock with a driver or loading a driver later using mount, see “Starting io-sock and Driver Management.” Unlike the FreeBSD version, you cannot load devs-em.so using a configuration file or by using loader.config.
