man_VBoxManage-bandwidthctl.xml@ 106001

Last change on this file since 106001 was 106001, checked in by vboxsync, 3 months ago

doc/manual/man_VBoxManage-*: Updated a variety of the VBoxManage help
files to improve readability, corrected some typos, and made various
other corrections.

src/VBox/*: Updated some comments and log messages for a variety of
source files to correct the spelling of 'suppress'. A few APIC files
and USB files use 'supress' in variable names or manifest constants but
those were not changed.

100	The <command>VBoxManage bandwidthctl</command> command enables you

106	Note that a network bandwidth limit applies only to the outbound
107	traffic from the VM. The inbound traffic is unlimited.
