Subject: [dpdk-dev] [RFC][PATCH 2/3] examples/vhost: Add vswitch command line options
Date: Sat, 27 Aug 2016 21:56:25 +0530 [thread overview]
Message-ID: <1472315186-28090-3-git-send-email-pankaj.chauhan@nxp.com> (raw)
In-Reply-To: <1472315186-28090-1-git-send-email-pankaj.chauhan@nxp.com>
Add command line options for selecting switch implementation
and maximum ports for the vswitch.following are two new command
line options:
--switch <switch_name> [char string, Selects the switch imlementation]
--max-ports<port_count> [int, selects maximum number of ports to support]
For example:
$ ./vhost-switch -c 3 -n 2 --socket-mem 1024 --huge-dir /hugetlbfs -- -p
0x1 --dev-basename sock1 --switch "vmdq" --max-ports 3
