Subject: fabrics: add option to override drivers queue depth also for connect-all command
X-Git-Tag: v1.3~2
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=748798c2549fbc3d751c17f81dce64d037f8cbc9;p=users%2Fhch%2Fnvme-cli.git
fabrics: add option to override drivers queue depth also for connect-all command
Currently it is not possible to override the fabrics drivers default
queue depth with the nvme userspace utility's 'connect-all' command,
but only when using the 'connect' command.
Add an option to override the drivers default queue depth for NVMe
over fabrics with the 'connect-all' command as we did previouslt with the
'connect' command.
