This is missing syntax notes. One might think that to enable it they need to say "enable", but in fact it's "on", and "off" for disabled. There should be an "{on | off}" somewhere in there. Also, line length. Also, the paragraph is imho a bit long-winded.

I'll fix the typo in the argument name, but about them being independent while that is true I used or, since they can't be configured using the same command whereas your proposed syntax gives the feeling that you can configure both in the same rdma system set command. > >> .ti -8 >> .B rdma system help >> >> .SH "DESCRIPTION" >> -.SS rdma system set - set RDMA subsystem network namespace mode >> +.SS rdma system set - set RDMA subsystem network namespace mode or privileged qkey mode >> >> -.SS rdma system show - display RDMA subsystem network namespace mode >> +.SS rdma system show - display RDMA subsystem network namespace mode and privileged qkey state > Maybe make it just something like "configure RDMA system settings" or > whatever the umbrella term is?

Will fix all line lengths, thanks for noting.
