n/a means parameter not supported by the current platform or kernel
Parameter types:
S = Static: cannot be changed
D = Dynamic: can be freely changed
B = Bosboot: can only be changed using bosboot and reboot
R = Reboot: can only be changed during reboot
C = Connect: changes are only effective for future socket connections
M = Mount: changes are only effective for future mountings
I = Incremental: can only be incremented
d = deprecated: deprecated and cannot be changed
Value conventions:
K = Kilo: 2^10 G = Giga: 2^30 P = Peta: 2^50
