Could you add read-only (CTL_RDTUN) sysctl-s for these two, to make it possible to easily check the current values?

1900

Could you reword it to indicate what the valid value would be?

202 ↗(On Diff #34886)

mdoc style is to start a new line after a sentence-ending full stop. So, something like

Specifies the maximum number of ports supported, which must be a power of 2.
The default value is 256

(similarly for line 200.)

Please remember to update .Dd on commit. Thanks!

s/The following/These/

200 ↗(On Diff #34886)

"Specifies the" doesn't add anything and makes the reader search farther in the sentence for what this actually is.

Maximum number of LUNs supported.
Must be a power of 2.  Default 1024.
202 ↗(On Diff #34886)

As above:

Maximum number of ports supported.
Must be a power of 2. Default 256.
